PURPOSE OF THE LABORATORY The ITS LABORATORY purpose is to provide an environment for ITS research, training, and education with a principle focus on traffic management and simulation research. This environment also facilitates ITS technology demonstrations, evaluations and comparisons of ITS technologies, and cooperation between researchers and practitioners. research assistants provide many of the skills for demonstrations. Researchers and their graduate student CTS management personnel, professors from various University departments, and the laboratory manager coordinate training and education sessions. BACKGROUND WHICH LED UP TO THE LABORATORY A Minnesota Guidestar task force created the basic requirements for a multi-purpose transportation laboratory in 1992/93 [originally designed as an Intelligent Vehicle-Highway Systems (IVHS) laboratory]. The task force included the CTS research director, Laurie McGinnis, several engineering professors, Mn/DOT traffic operations personnel, and Mn/DOT Office of Research Administration personnel. Development started in March 1994 with the hiring of a laboratory manager. He created a development plan which detailed a requirement set [Attachment A] based on the task force's report. The Guidestar Program provided $300K for design, $1M for build and $165k for operation during the four 1/2 years covered by this report. These funds were supplemented by research project hardware & software contributions, discounted vendor hardware,

23 cooperative installation support, donated training, free equipment space at the Traffic Management Center. SIGNIFICANT DEVELOPMENT MILESTONES Milestones of significance during the design, build, and operation are as follows: 1994 Events 1995 Events 3/94 CTS/ITS Institute hired a development laboratory manager. 8/94 Development plan approved by ITS Institute Steering Committee. 10/94 CTS moved into the new Transportation and Safety Building. 12/94 First laboratory furniture and three Blue Star P-90 computers installed. 3/95 Open house for CTS new facility with si functional researcher positions. 5/95 Networked seven PCs with a Novell server plus two UNIX workstations. 6/95 Installed and operated an AutoscopeM machine vision unit with a rooftop camera aimed at the Washington and Union intersection. 7/95 First operation of a pan-zoom-tilt traffic surveillance camera from the TSB roof top including video link to campus parking lot and parking ramp surveillance system. 9/95 Activated a 40 channel microwave link bringing live traffic video from the TMC for display on a nine monitor video wall eight monitor video rack. 11/95 Activated of a fiber optic video link between the ITS Laboratory and the Human Factors Research Laboratory to demonstrate driving simulator scenarios Events 1/96 Satellite down-link into classroom and laboratory via Campus Cable System. 2/96 Installed a data distribution server at TMC. 4/96 First live traffic data transfer from TMC into Oracle data base structure. 5/96 Our first System Technology Inc.

25 CHAPTER 2 - NETWORK AND DATABASE ARCHITECTURE INTRODUCTION TO FUNCTIONALITY ITS Institute Management decided in 1994 to develop the operational architecture and traffic database using a combination of coordinated research projects and eternal recommendations instead of using consultant companies for design and build. The result has been a network evolving from basic Ethernet communications to an integrated system providing services to research projects. This chapter summarizes the ITS LABORATORY functionality and the activities which have taken place in the definition and development of a traffic flow database. Details are contained in the individual research project reports that implement the various parts of operational system. The data base purpose is to support research into net generation Traffic Operation Centers (TOC) as well as those research projects which intend to use real time data in conjunction with historical data. database also forms a foundation for traffic simulator research project input flow, data flow linking with incident management research and ITS technology demonstrations. The This design combines previous research results, consultant recommendations, current projects needs, and research project work plans [references listed below]. It also includes the discussions from numerous meetings with University Principal Investigators, graduate research assistants working in the laboratory, research fellows, and Mn/DOT personnel. network and a couple of free standing UNIX workstations. The laboratory begin with a Novel NetWare based local area A Gardner-Rowe analysis recommended that we implement an NT based network to facilitate use of the Tele-Communications Protocol/Internet Protocol (TCP/IP) communications. The result is in figure 2.1.

27 DATABASE PLANNING Actions 1) Start with the Mn/DOT implementation of "Archival of Traffic Data Phase I" to meet the basic 5 minute infrastructure core requirements for a traffic data base. 2) Hire a computer science graduate student to install this core in a laboratory computer. Connected it with an Internet 'name pipe' socket data flow from the Data Distribution Server (DDS) at TMC to meet the real-time data input need. 3) Purchase and installed the hardware and operating system configuration needed to support real time access to the database from multiple concurrent projects (see functional description). 4) Coordinate the initiatives of several other research projects to promote cohesion and avoid duplication within and between the following projects. * "Development of Traffic Simulation Laboratory: Phase II" research project with Dr. Panos Michalopoulos as the Principle Investigator (PI) - [Ken Reynhout as Research Fellow], * "Activation of laboratory for ITS Operational testing" research project with Dr. Panos Michalopoulos as the PI. [Ken Reynhout support], * "Data Tool Project" research project with Dr. Jaideep Srivastava as the PI, * "Weaving Capacity" research project with Dr. Eil Kwon as the PI, * "KRONOS" support project with Dr. Eil Kwon as the PI, * "Development of ITS Lab Pilot for Future Traffic Operations Center" research project with Dr. Panos Michalopoulos as the PI (formerly Dr. Stephanedes), * "Mn/DOT database implementation" project with Jim Aswegan as the PI, and * Archival of Traffic Data at IVHS Center, Phase 2: Scaling Up to 30-second Data; with Dr. Shashi Shekhar as PI. 5) Negotiate an update to the laboratory's TMC interface based on findings of the above projects. 6) Develop a net phase information system data acquisition and distribution plan for to include: * Distribution device linkage with the Mn/DOT Orion project data distribution nodes, * Integration of local street sensor data, and * Weather data systems. 13

28 Traffic Database Status -June Plan item 1 The selected base line has an issue in that Mn/DOT reports queries are slow, especially during data load periods. We've concluded that enhancements couldn't be defined until the specific bottlenecks are identified by further research analysis and studies. This analysis is/was in process by Dr. Shashi Shekhar as Phase I of the data Archiving Project. Plan item 2 A computer science graduate student, Davis Jose, was hired for the 1996/97 school year. He installed NT server 3.51, Oracle 7. and the Mn/DOT database structure into an eisting computer in the Laboratory. Mr. Jose received a name pipe client software routine from Mn/DOT (Jim Aswegan), tailored it with C" for NT 3.51 server and Oracle, then integrated it into this laboratory unit. This eisting computer, as we epected, only had capacity for a couple day's freeway data. Our performance measurements showed that 45 seconds was needed to load a 5 minute data set in real time, the actual Internet transmission time is but a fraction of this period. At the request of Dr. Kwon and Mr. Aswegan, Davis also created a C++ software routine to etract data sets from the data base. Issues needing resolution are: 1. the Oracle relational database tool and associated 5 minute structure could bog down when receiving a data stream every 30 seconds, 2. a higher capacity PC is needed, and 3. client (user) access requires knowledge and skills with Software Query Language (SQL). Plan item 3 A new 'data base' PC with 16 gigabytes of hard drive space was ordered then installed in September of 1997 as part of the laboratory LAN conversion from NetWare 4.1 to Win NT 4.0. This addressed issue 2 of Plan item 2. As recommended by reference 3, the Orbi Common Object Request Broker Authority (CORBA) development suite was purchased to use in mapping real time data distribution functions with the TCP/IP communications protocol. This suite has both PC and Sun client licenses. 14

29 Plan item 4 Several meetings have been held. Reference 2 has been re-structured to address the issue of plan item 1 and the third issue of Plan item 2. Two of Dr. Shekhar's graduate students worked with the Mn/DOT database structure in the laboratory. An initial demonstration showed data etraction using a worksheet SQL method via a simulated WEB site. Dr. Michalopoulos' traffic simulation lab project [research fellow Ken Reynhout as principal programmer] used the Orbi software to create the real time distribution function and the PC client for the first simulator input. The former Dr. Stephanedes TRACLAB project (John Hourdakis as research fellow) is epected to look at a UNIX client for CORBA. The distribution capability was demonstrated in January, Several issues still require resolution: 1. Coordination of the Myriad tool project [Dr. Srivastava] to route queries to the archival site or local PC data base or data flow processor. Should this run on the lab's HP or LAN server or another PC? 2. Should the Weaving project [Dr. Kwon] send it's queries to the local PC data base or to the Archival site or to the Myriad tool or should it become a data flow processor client? 3. When should the KRONOS software support project adapt a database client to replace the present manual data input process? 4. When and how do we develop a real time data input from the Lab's Autoscope T Scope server installation? Plan item 5 No update requirements identified to date, Ron Dahl at TMC considers the Data Distribution Server PC performance and capacity to be adequate. An integration of Autoscope T sensor data with loop detector data wthhin the TMC system is in the planning stages. A major issue to be resolved is the data quality or accuracy. Do we implement a filter in the data distribution PC at TMC or in the Data Flow processor in the laboratory, or let each client user implement an individual project filter. We have looked at the "Ball Engineering" client software being used for the highway helper and Trilogy projects. This software operates as a client to the TMC DDS. As with the Oracle DDS interface, this customized interface isn't adequate for a store and forward 15

30 distribution function that we need in the laboratory. This package does include a data filter to detect missing or in-accurate loop data. Our laboratory infrastructure will use the same or a similar data accuracy filter comparable to Ball's before distributing data outside the University. Plan item 6 Considerations for net phase planning are: * The May, 1997 Douglas Consulting feedback is that our internal network wasn't ready for WEB site access. * The Mn/DOT Office of Advanced Transportation Systems has canceled the planned "Large Database on a WEB Site" project therefore an alternate implementation approach will be needed. * Transition to a direct Advanced Tele-communications Mode (ATM) network within the laboratory is not a requirement. * The University's Network and Telecommunications Services has recently (4/98) completed a building to building conversion from token ring to ATM for internet access and communications. * The new hubs associated with this change are giving faster LAN operations. DATABASE DESCRIPTION The Intelligent Transportation Systems LABORATORY requirement is for a robust real-time interactive traffic database as an integral part of its' research support infrastructure. architecture is illustrated in figure 2.2. The database records are to contain periodic traffic data and various sensor data. The periodic data are the 5 minute and 30 second data presently collected from loop detectors by the Minnesota Department of Transportation's Traffic Management Center. The various sensor data are flow measurement data from machine vision and/or transportable sensor type sites as well as hourly weather data from several sites. This The geographic references of the structure have to be coordinated with the Twin Cities freeway network as well as the interconnected major streets of the area. The database query structure has to be diverse enough to etract subsets of data based upon roadway sections with respect to time periods or upon time periods with respect to roadway sections and intersections. The query structure needs direct access to the most recent three-month period of 5 minute data [direct means not having to insert a CD_ROM or disk or tape]. 16

ITS Laboratory Traffic Data Architecture The infrastructure must also support 5 minute data comparisons of any of these most recent three months with history data files [archived records] of earlier months. The infrastructure must support immediate access to two days of complete 30-second data [current and yesterday]. It shall provide immediate "snapshot" access of 30 second data records from incident areas/times for a period of a month. The infrastructure must also support access to "snapshot" history data files (records) of previous months. The first level of detail is shown in figure 2.3. In May 1998 the database team decided to implement a WEB site on the primary NT server, URSA.itslab.umn.edu, for researcher access to the three most recent months of 5-minute data. The CTS Librarian was identified as the WEB Master to provide image continuity with the CTS Information/Outreach sites. The loading of the Traffic Database will take place either monthly or weekly or daily using the mndotftp@gemini.itslab.umn.edu FTP site. A method of increasing storage size of the server is necessary. Also a password scheme will be developed in order to control access to approved researchers. Specific information about the schema for this update is to 17

These ladies have written Master's thesis from this work, contact Dr Shekhar for copies. It was decided to defer an operational implementation of the database system until an Oracle skilled operations manager was hired. 18

35 CHAPTER 3 - REAL TIME VIDEO IMPLEMENTATION INTRODUCTION TO VIDEO This chapter documents the video system design for the Intelligent Transportation Systems Laboratory at the Center for Transportation Studies. The video system consists of 40 microwave channels from the Minnesota Department of Transportation's Traffic Management Center, several local video sources, and a broadband distribution network in the Transportation and Safety Building on the University of Minnesota's Minneapolis campus. The video system purpose is to support ITS research projects, to demonstrate ITS technologies, and to facilitate the CTS training and education mission. The operational status of the system may vary slightly from the design depending upon the specific research project being supported or the repair urgency of a particular hardware problem. TRAFFIC MANAGEMENT CENTER In 1995 the Mn/DOT TMC had 176 surveillance cameras and 32 machine vision cameras on the 235 freeway miles in and around the Minneapolis/St. Paul metropolitan area. By the year 2000, there will be over 200 surveillance cameras. Video signals from the Mn/DOT surveillance cameras are distributed to TMC control room display banks and to traffic management operator stations via a output base band switch. TMC video switch outputs are also distributed to the Highway patrol's 911 center at Water's Edge, to Hennepin Co., Mn/DOT maintenance departments, Paragon TV, the Minneapolis Traffic Engineering Building, local TV stations, and the City of Saint Paul. A critical consideration in sharing video collected and provided by the TMC is to avoid degradation of their video signals, therefore direct "T" connections to the video switch are restricted. Instead, the University's shared installations connect co-aial cables to the video output of displays in the control room or to the amplified input to the Autoscope units in the basement T electronics room. These video signals are connected to University provided modulators, which in turn feed radio frequency (RF) co-aial cables. The cables connect to a microwave subsystem, which transmits the video channels 2.3 miles to the top of Moos Tower on the University campus. From Moos Tower, the signal set is linked with a Radio Frequency repeater to the video electronics 21

36 room of the ITS LABORATORY. included as Attachment C to this document. Schematics of the University equipment installation at TMC are The principal research, education, and training objective of real-time video from the TMC is incident detection research using machine vision equipment strategically placed along the corridor. A logical etension of the automated detection is the verification and subsequent advisory messages to other drivers and response teams, i.e. the management of the incident. This simple objective guided the video connection selection as detailed herein. The microwave license is for 70 channels, therefore this TMC to University system could be epanded in the future to provide additional channels to the laboratory or to have the receiver at the top of Moos Tower become a relay to other sites. Table 3.3 lists the all 40 video channels presently transmitted via microwave, note that the laboratory channel # frequencies were carefully chosen to avoid the area's commercial TV channel frequencies. Machine Vision Incident Detection The TMC has thirteen machine vision fiber optic video connections from a 3.5 mile section. One is the multipleed selection from the si Autoscope T units [22 cameras] presently located in a cabinet adjacent to the Highway 100 intersection west of Minneapolis. The other twelve are the video inputs from non-multipleed cameras along between Wirth Parkway and Penn Avenue. Four of these are connected to an AutoscopeM unit in the TMC telemetry room. This video is used to eperiment with incident detection and ramp metering strategies based on machine vision detection. It is also used to correlate detection algorithms with the digitized loop detector data which is linked to the laboratory from TMC over an Internet path. Details of this Machine Vision Laboratory (MVL) connections and operations are in the March 1997 research report, "1-394 Laboratory Activation" authored by Ken Reynhout and Dr. Panos Michalopoulos. Internet operations are described in the laboratory's database design document. Table 3.1 presents an overview of the camera locations and their connections. TMC surveillance cameras #905 through #917 cover from its Highway 169 intersection to the 1-94 junction. This includes the 3.5 mile AutoscopeM camera installation area. These surveillance camera outputs are displayed on the North Station, monitors #17 through #28 as a 16-second stage of their eight salvo sequence. 22

While watching the desktop monitor, the operator will pan, zoom, or tilt the selected camera to verify the incident. Then the operator follows TMC standard procedures for recording and taking action. Since verification of incidents and avoidance of false alarms is paramount to an incident management system, the video from the North & South operator stations, the KBEM announcer station, the Trilogy/Genesis data capture station, and the information officer stations are also sent to the laboratory. Table 3.2 lists these along with their channel numbers. Updates to this portion of the video design are recommended in Chapter 6. Channels 22 and 24 were assigned to this 'action station' section in anticipation of action station emulation with automatic camera selection in the ITS Laboratory. 23

A previous Civil Engineering & TMC cooperative research project for ramp meter optimization tried some algorithms on the freeway section in the Highway 62 and I35W commons area. The ability to observe this area during future cooperative tests and trials was the incentive for us to select South Station monitors 41 through 46 which display cameras #613 through #620 as part of a 13 second salvo sequence. This covers Interstate I35W from 8 6 t St. to 5 0th St. including the commons area with Highway 62 cross-town freeway. Arterial Street Integration A third research thrust at the University deals with arterial street connections to the freeway system. This research would be conducted in cooperation with the Cities of Minneapolis and Saint Paul, therefore it is anticipated that concurrent observation of the same video screens could be beneficial. Monitors #B63 and #B61 input to the transmission system provide a common visual reference screen with each of these cities. 24

40 UNIVERSITY VIDEO The ITS LABORATORY has complemented the microwave link with other video sources for research and demonstrations [table 3.4.] These operate entirely on coaial cable within the TSB, therefore duplication of local television station frequencies and channel numbers is not a concern. The Mod # refers to the modulator number coupling the video source to the RF system. We've also installed wiring from room 214A to several points in the laboratory walls for future connections to computer video board outputs. A fiber optic connection to the Transitway machine vision installation is partially completed, awaiting a research, evaluation, or operational project need to install the communications electronics. Chapter 6 provides recommendations to activate this future capability. Channel # Source Mod Notes Table 3.4.

41 ITS Technology Demonstrations The ITS LABORATORY is visited by one or more groups per month as transportation professionals from other states and countries come to observe the Minnesota Guidestar Program successes. Live video from the freeways instead of video taped scenarios enhances the research presentations to these tour groups. Being able to replicate the North and South station display salvo sequencing lets the visitors observe the freeway system traffic flow with glimpses from over 130 cameras as well as the camera zooming actions of the traffic managers. While the TMC Traffic Managers verify incidents or scan the freeway system, laboratory personnel can virtually look over their shoulders from the laboratory, Table 3.2 listed these observation points. VIDEO DISTRIBUTION SYSTEM The laboratory video design in the University's Transportation and Safety Building has an RF distribution system and a suite of displays for research, training, and demonstration purposes. A broadband system is analogous to a cable television system. A modulator converts the National Television Standard Code (NTSC) video signal to an RF signal. A demodulator converts an RF signal to an NTSC video signal. The tuner of a TV or Video Cassette Recorder (VCR) provides the same electrical function as a demodulator. Primary Laboratory -TSB Room 214 Figure 3.1 is a schematic of the VCR and associated projection equipment of the laboratory. There are two overhead projectors in the laboratory, each with three inputs. On each projector input Video 1 is connected directly to a VCR in the area. Input Video 2 is connected to an individual demodulator. The Red Green Blue (RGB) input is connected to a PC's Video High-Sync (VHS) output. The VCRs attached to the VI inputs also have their outputs fed to a modulator feeding the RF system so that a tape could be played at one location and viewed on any other system TV monitor. We've also connected the Super VHS video modules of a Silicon Graphics machine to this area's VCR to facilitate multi-media demonstrations. A researcher is working on a comparable Sun workstation connection to do eperiments with mouse controlled pan, tilt, and zoom techniques. 27

A few individual VCRs are used as RF tuners to feed signals to Autoscope units. This design lets researchers work with either live from the roof top camera or from the cameras via the TMC as well as recorded video. The video wall and video rack details are discussed in a subsequent section of this chapter. Demodulator #47 and modulator #62 are interconnected for research 28

43 purposes, i.e. to show that a computer using an RS-232 control sequence is capable of automatically controlling both video inputs and outputs. Video Distribution Outside the Primary Laboratory The video distribution system etends to several on campus destinations, figure 3.2. This figure also shows a couple of bi-directional connections and the rooftop AutoscopeTM camera. The HFRL connection lets the ITS Laboratory observe a portion of their wrap around driving simulator scenes. This connection also lets the HFRL observe a TMC video channel or other source as selected by demodulator #45. The bi-directional connection with the Parking and Transportation Services lets the laboratory distribute TMC video into their system or lets the laboratory connect to their system. These observe the on campus parking lots, garages, and ramps. The laboratory has a Burle video control console at LOC05 that lets us select any one of their 400+ cameras for viewing. We also have special permission to demonstrate pan, tilt, and zoom capabilities of the surveillance cameras located on the upper comers of the TSB above Washington Ave. (#677 & #678). One of these is 10 feet away from our roof top Autoscope camera thus providing both detection and surveillance of the Washington Ave. and Union St. intersection. The campus surveillance camera numbers are: * 0-14 Trunk feeds * ' Ave. Ramp * Weisman Garage * East River Road * Oak Street Ramp * th Street Ramp * Washington Avenue Ramp * West Bank facilities * 900- yyy Church Street Garage 29

45 The Campus Cable system is setup with several channels from various centers on campus. Our demodulator #46 and modulator #2 provide the laboratory with a unique capability. This linked conversion allows us to subscribe to occasional satellite down link distributed transportation seminars. When active, we can show the down link in the classroom #219 [25 person capacity]; the east conference room #229 [12 person capacity]; four staff offices [210, 213, 215, & 216], two overhead projectors; the video wall; and several of the research positions in the main laboratory. The channels available via the laboratory's channel 2 are listed in table 3.5. We also added a VCR/Monitor with earphones to the library area to facilitate researcher review of the transportation video tapes available in that CTS area. Table 3.5.

The display system consists of the video wall, the video rack, projectors and individual Video Wall The ITS LABORATORY implemented a video wall in two stages. Stage 1 implemented the base and the nine gray units as shown in figure 3.3. Stage two added seven additional units. Note that the numbering sequence is as would be viewed from the front of the unit. The installation measures 8.5 feet high, 10 feet wide at the base, and 2.5 feet deep. The individual monitors are 27" diagonal color displays. The base cabinet was built by the University's mill-work shop. The Video Wall electronics are preset for si configuration sets using inputs from the Laboratory's broadband RF system. The result of the si programmed shows gives the display combinations shown in figure

University owned modulators are connected to the video out port of these twelve monitors. The modulator outputs are combined with the AutoscopeTM channel modulators and connected to the microwave input electronics. Individual monitors in the laboratory, offices, and conference rooms 34

49 can be tuned with a remote or with the front controls. The individual displays in the video wall are tuned with demodulators #1 through #16 via the Option 20 software eecuted from LOC05, LOC06, or the lab manager's office depending upon the RS232 switch settings. The Traffic Management Center's video distribution system overlays each switch output with a two lines of information as described in Table 3.7. Table 3.7. TMC On-Screen Information The Parking and Transportation Services switcher overlays camera # and locations in a similar fashion. Note that this information doesn't show up on the Autoscope TM channels because those signal sources don't go through a base band video switch. A location message also doesn't show up on some of the traffic management screens that are direct computer outputs. Video Rack The video rack has eight demodulators connected to eight monitors. The left-si are usually programmed to replicate part of the TMC South Station display bank. The salvo display cameras are listed in Table 3.8. The other two monitors in this rack are usually show intersection cameras at and Penn Ave. [demodulator #24] and at Washington and Union [demodulator #28]. Demodulator #28's output is also amplified and fed to input port #2 of each of the Autoscope Units in the laboratory so that trainee's can work with the same live video. This also reduces the number of individual VCRs or demodulators needed for the system. The laboratory has the capability to observe the majority of the traffic around the Twin Cities because of the TMC salvo operating system. 35

For area 1 [figure 3.7], we've incorporated a wireless microphone to support an instructor's voice when teaching. The FM radio system located in the electronics' room is usually tuned to station MHz for two reasons. During normal working hours there is soft background music. During rush hours, the people using the lab or visiting hear the traffic reports every 10 minutes from the TMC. This system is also fed to the adjacent skyway so that casual observers can hear as well as see what is happening in the laboratory. Also, if a video tape is being played on the video wall, it's audio is played through the wall mounted speakers as well as in the skyway. The Wireless Receiver, Audio Multiple, and Frequency Modulation (FM) Radio System are all located in the Electronics Room, #214A. We've also installed the "pink noise" electronics for the entire floor in this room. 36

53 CHAPTER 4 - ITS LABORATORY LAYOUT INTRODUCTION TO PHYSICAL This chapter describes the physical aspects of the Intelligent Transportation Systems laboratory, a part of the Center for Transportation Studies at the University of Minnesota. It includes the Ethernet, telephone, Integrated Services Digital Network (ISDN), and modem connection locations as well as the power distribution design. The laboratory is located on the second floor of the Transportation and Safety Building at 511 Washington Avenue South East on the East Bank campus. FLOOR PLAN DESIGNS The original floor plan build started in November 1994 with si of the nine research positions available at an open house on 3/5/95. The workstations (WS) are labeled WS1 through WS9 in Figure 4.1. The University's mill works shop built the furniture using the laboratory manager's designs which were roughly based upon the Mn/DOT Traffic Management Center traffic operator desks. The top third [in fig. 4.1] of the laboratory features a video wall, VR1, designed to emulate a Traffic Operations Center. The lower left third of the laboratory with three PC workstation positions and a video rack, VR2, was designed to support machine vision research. The lower right had three workstations for traffic flow simulation and report printing. We installed a 90 Mega-Hertz (MHz) Pentium processor with 32 Mega-Bytes (MB) of Random Access Memory (RAM) and a 500K Hard Drive (HD) at seven locations [1994 state of the science.] These were networked with a 90 MHz NetWare 4.1 server with 64MB RAM and a 1 Giga-byte Hard Drive located in the manager's office. PJ1 and PJ2 symbols in the left and right center of the drawing are the locations of overhead projectors aimed at two pull-down screens along the south wall of the room. These provide large screen demonstration displays in these two areas. Project needs added an SGI computer at WSO, an HP computer at WSa, and a 486DX PC at WSb. Professors and their research assistants worked on several research projects within this initial "3 theater" plan through the summer of

54 Figure 4.1. Original Laboratory Floor Plan (1995 & 1996) After almost two years of researcher use, a couple of workshops in 1996, and a heavy influ of visitors during the summer and fall of 1996; it became very obvious to the laboratory manager that the initial design wasn't optimum to serve the multiple purposes of the laboratory. In the fall of '96, a revised floor plan [figure 4.2] was developed with the following redesign objectives: * to accommodate individual project separation and co-mingling needs, * to better utilize the physical space available with improved video sight lines, * to improve the working comfort level of the research assistants in the laboratory, * to provide a research infrastructure facilitating future Traffic Operations Center research initiatives, * to support growth of the Penn State - University of Minnesota Alliance (PSUMA) program, and * to support the emerging FHWA Professional Capacity Building initiatives. This initiative to revise the floor plan was approved by the ITS Institute's Steering Committee at their November 5, 1996 meeting. The major change was to orient the South 2/3' of the laboratory more like a classroom with an instructors position at location 6 [labeled LOC06] at the lower left of figure 4.2. Basic student positions are LOC03 and LOC07 through LOC14. Civil 40

55 Engineering Class 5300 began using this facility to conduct hands-on Highway Capacity Software class. Thirteen of these fifteen locations in the laboratory have 46 square feet of individual researcher space [LOC02 and LOC06 have just 25 sq. ft.]. This re-design keeps the American's with Disabilities Act (ADA) pre-requisite 3' 8" aisle down the middle, in front of the video wall, and into the electronics room. We installed re-movable partitions along the center aisle to provide researchers with a little privacy. Figure 4.2. Revised Laboratory Floor Plan (1997) Several events occurred in the summer of 1997 causing us to move toward additional revisions resulting in the figure 4.3 layout: * A University network audit recommended locking up our network server, thus we created an administrator position in the electronics room [top right.] * Maintenance access to the video rack rear [figure 4.3 lower left] was difficult so we shifted LOC06 net to the south windows and moved the parts cabinet. * Researchers complained about the noise of printers and copiers at LOCOO therefore we rotated a credenza and installed a noise absorbing partition. * The West Conference room was re-allocated as office space for the new ITS Institute Program's director therefore we moved our PSUMA driving simulator to LOC16. 41

56 S Visitor's offices 205 & 207 were allocated to the Regional Growth Project thus we installed a partition by the printers to create some visiting researcher privacy at LOC15. Figure 4.3. Floor Plan with LOCOO & LOC15 Changes (1998) POWER DISTRIBUTION AND CONTROL We designed the power distribution to minimize noise coupling between equipment by providing an independent circuit breaker for each position. The method uses a central grounding point, characterized by orange power jacks. This indicates that the third wire safety ground is isolated from the normal ground. Circuit breakers are in the electronics' room or the Janitor's closet [room 217.] The outlets in the electronics' room, the manager's office, the communications closet [room 206], and LOC01 through LOC05 are connected to the buildings Uninterrupted Power Supply (UPS) supplemented with a 25 Kilowatt emergency generator. We've labeled each outlet with the controlling panel and circuit breaker. Each workstation is equipped with a surge suppressor power strip. All power wiring within the laboratory is routed in chases along baseboards 42

57 or under the workstations. The chases have a middle metal barrier to separate power and signal cables. The dotted lines in figure 4.4 illustrate chase locations. 2 Video Wall Switches Chases on floor 3 Area Light Switches Screen Control for PJ1 & PJ2 Figure 4.4. Power Installation Routing There are no hang down wires nor up through the floor wiring installations. We also made sure that there would be no wiring etended across the aisles or chair movement areas. The building architect's wiring design had the overhead lights for the entire room and the hallway leading to it on one circuit controlled by two way switches by the entry doors. In order to conduct demonstrations in each laboratory area, we designed to allow separate lighting control in each third of the laboratory area. The power control switches for the pull down screens for PJ1 and PJ2 were located adjacent to the light switches for the areas. For the video wall, we designed to have the base cabinet wired directly back to the circuit breakers then put two on/off switches in back. Each controls half of the video wall. The tuner electronics in the base are left on all the time so that we don't have to re-select (re-tune) on a daily basis. The last design detail was a ceiling mounted outlet for a large digital clock in the center of the south wall. 43

58 NETWORK & TELEPHONE CONNECTION LOCATIONS Telephone, Ether jack, and modem connections are located around the periphery of the laboratory. The approimate physical locations are indicated by Ref. # 1 through # 8 in figure 4.5, clockwise around the room beginning behind the printer area. These wall jacks are wired with type 5 cables to the Telecommunications Department wire racks in room 206. Type 5 wiring etends from the wall jacks to individual workstation locations using chases or cable ways under or within the furniture, shared with the power distribution which was illustrated in figure 4.4. The connections at references #6 and #7 were added during laboratory updates. 44

59 r7 #5 #8 #4 #3 #2 #1 Figure 4.5. Communication Connection Locations Table 4.1 provides a list of the telephone or modem connections within the laboratory. We used the NT server-workstation labeling to document the NT connections as illustrated in figure 2.6. Note that the Uni based computers at Locations 4, 5, and 6 don't show up on this NT screen. Table 4.2 provides a matri of these locations with the Telecommunications Wall Grid reference numbers and assigned IP addresses. To track the Internet Protocol numbers within the laboratory, we've also labeled each computer with the associated computer name and IP address. Table 4.1.

We painted the chases from the ceiling to baseboard to match the walls thereby maintaining the showcase image of the laboratory. It should be noted that the router and hubs for University sub-net are located in TSB room #206. The Frame-Cloud Relay port of the router is used by the University. Police Department for communications with the Minneapolis Police Department. There is a spare "high speed" port on this router should the laboratory ever need a special connection directly to another location. The sub net is wholly used by the ITS laboratory thus local communications do not compete with the rest of the building. In 1996 we installed an ISDN line into room 206, call # , in preparation for communications with the 1-94 Smart Work Zone project and/or teleconferencing. The line was wired for selective use at two lab locations, the classroom, and the East Conference Room. The line was disconnected in 1998 when needs did not materialize. 48

65 CHAPTER 5 - ITS LABORATORY OPERATIONS INTRODUCTION TO OPERATIONS This chapter documents the laboratory operations policies and support duties. It includes the network and computer use policy, copier/printer policy, facility access policy with the alarm procedure, the network administrator duties, the security services duties, the laboratory manager's administrative duties, and the laboratory users list as of June Note that most of these sections are written for bulletin board posting or new user information discussions. NETWORK AND COMPUTER USE POLICY The NT domain is itslab.umn.edu, the primary server is URSA.itslab.umn.edu, a dual processor Pentium 200 PC. The UNIX Network File Sharing is controlled by gemini.itslab.umn.edu, a Silicon Graphics Indigo 2 computer. Emergency Smoke, Fire, Injury, and threatening situations should immediately be reported to the University Police on the first floor, phone Problem Reporting The Computer Science (CSci) Systems staff is responsible for the local area network, basic NT operation support, and our three UNIX machines; Gemini, Castor, & Pollu. If a user has a problem with your password or file sharing or file restoration from backup, he/she is to call their help Ecluding official University holidays the help line hours are 7 a.m. to 10 p.m. on Mon. = > Thurs., 7 a.m. to 8 p.m. on Fridays, and 10 a.m. to 6 p.m. on Saturdays and Sundays. If harder problems arise that can't be solved over the phone, the user sends an message to operator@cs.umn.edu with a copy to the laboratory manager itsmail@tc.umn.edu. Include the computer name found on the keyboard, the IP address, and the physical location in the laboratory from figure 5.1 as part of the problem description being reported. Hardware problem 51

66 resolutions are the lab manager's responsibility in coordination with the PI overseeing graduate student work at individual workstations! Center for Transportation Studies Ave. SE #200 Minneapolis, MN IT S LA ATO511 Washington ITS LABO ATO Y Figure 5.1. Laboratory Locations for Problem Reporting Basic Network Functions The basic NT functions provided are network access control, Office 97, virus protection, periodic backup, Internet tools, file sharing control, utility support software, and printing. The CSci Systems staff maintains these software packages with periodic updates and service packages using automated scripts in the wee hours of the morning. * All users log on to the domain, possible from any NT workstation within the laboratory. The individual display setup follows as a roaming profile, ecept for special *.bmp pictures that may have been configured on individual machines. NOVA will automatically take over should 52

67 URSA have a hardware problem. In this case, the profiles will automatically move and we can transfer data from the backup tapes. * Office 97 is installed onto each NT workstation thereby giving individual users the best performance. This gives the individual researchers WORD, EXCEL, ACCESS, PowerPoint, and Outlook. * Dynamic Virus Protection in the background on each NT machine, users should notify the lab manager and CSci operator immediately if they suspect a virus problem or hacker attack. Additionally, each machine is scheduled to do a hard drive scan in the early hours of the morning using the same virus protection software. * URSA and NOVA get a full backup once a week on Wednesdays and a partial backup the other si nights of the week. Individual NT workstations get a full backup once a week. These occur every Wednesday morning between 1:00 and 4:00 a.m. The UNIX machines also get a full backup once a week. This PC backup approach uses a four tape rotation with the most recent tape kept at the laboratory manager's home. * Our WEB browser choice is Netscape Communicator primarily because the Microsoft Internet Eplorer provided with NT 4.0 has some potential security problems. This Communicator can be configured to handle individual , see Lab manager to setup your user profile. Other browsers will be dis-allowed if individual PC hard drive space becomes an issue. * File sharing or not sharing is controlled on the server for you as a user & project participant to decide. Each user has a home folder H:\userid dedicated for personal use files. If you have data or information which you intend to share, there are three controlled folders under soft02 Q:\All Users, Q:\Staff-Researchers\, and Q:\Staff\. * Common support software is on URSA, Soft02 Q:\. The Util folder contains \Winzip, \TELNET, \FTP, \Gopher. Users should to create a "shortcut" to these from individual profile screens - ask for help if you haven't created shortcuts before. * Printers must be setup in individual profiles, contact the help desk if you can't print to both printers. * Staff office computers have a NetWare client installed to facilitate connection to the Cts_server's G:\ drive for data sharing. This connection also provides F:\ drive for CTS personal data storage. CJ Melco, CTS User Service Specialist, is responsible for these accounts and passwords. 53

68 Application Software Compilers, simulators, development tools, Autoscope t software, database software, etc. will be installed onto individual machines as needed. These installations should be coordinated by the project Principal Investigator with a CSci Administrator and the laboratory manager. Eamples are: * Highway Capacity Software is installed onto each PC to support Dr. Davis' CE5210 class. * AutoCAD R13 is installed on LUNA to support student drawing classes. * The Borland Compiler is installed onto two machines to support KRONOS maintenance. * Microsoft Visual C + + is installed onto most other PCs for project compiling. * ORBIX is installed into Polaris, primary use, and MARS, backup use, to support real time data flow software development. * Gensym is installed into the Pollu [Sun] and Polaris [PC] to support incident detection research. * MODSIM is installed into two machines to support controller research. Appendi E lists the PC software installation primary directories. Procedures for Users * Logoff when leaving workstation for the day, turn off power on the monitor only (an eception is allowed if you must set up an overnight batch processing job.) * Use the screen saver password feature if just going to class or lunch or upstairs but not if leaving for the night or weekend. * Try to (save) keep all of your creations in your H:\userid folder or sub-folders instead of on individual machines, that way you will be able to do work from another machine if your primary fails. This also provides for backup from tape in the event that you inadvertently erase a file or if individual PCs fail. * Set your preferences and options in Office97 - Word, Ecel, PowerPoint, Access, and Outlook to do automatic saves every 10 minutes or 15 minutes to avoid significant data loss that result from unepected machine or system crashes. * If you don't plan to work over any weekend or holiday, please feel free to shut down the processor in addition to the monitor at your primary workstation (ecept for servers). * Researchers should update their password on a quarterly basis. 54

69 * If you will be leaving the University or no longer working in/at the laboratory, coordinate file transition with your mentor or project Principal Investigator, we'll archive project files at the quarter end following your departure. NETWORK ADMINISTRATOR DUTIES The systems staff of the Department of Computer Science provides day-to-day support services to the Intelligent Transportation Systems laboratory for network, workstation, and PC base line operations as described in this section. This Agreement continues the network and PC operations support which started in July, It continues the UNIX workstation support which began formally in March, informally in May, CSci staff and the ITS laboratory manager established the base line network and PC system interconnect. This agreement specifically ecludes any Center for Transportation Studies' PCs which use the CTS_Server access as their primary networking interface. This agreement ecludes the laboratory's video network and associated equipment ecept for the few video capture boards and their 'driver' software. following sections provide a description of the base line services and revision guidelines. The Administrative Services Operation of the laboratory is most efficient when processes are in place to manage user changes and technology changes. Account management - Maintain accounts for administrator, staff, researcher, and student access levels. no guest level. Users will be added or deleted at the request of the laboratory manager. There is Data and network security - Ensure that proper procedures are in place that require the use of passwords that meet acceptable University security standards. Implement appropriate safeguards to prevent unauthorized use of systems. Monitor systems for break-ins. Close individual accounts and force password changes when compromises occur. Monitor and implement CERT and other advisories that identify security problems in vendor supplied software. 55

70 General support - Staff a help line which provides phone, , and in-person support from 7:00 = > 22:00 Monday through Thursday, 7:00 = > 20:00 Friday, and 10:00 to 18:00 Saturday and Sunday; ecluding official University holidays. This help line will respond to questions, problems, and requests from ITS LABORATORY users in a timely manner, i.e. user id additions within 24 hours and configuration changes or installations within three working days. LAN Operations - Maintain the local area network in the ITS LABORATORY and its connection(s) to the University's backbone network. Develop and test backup procedures and policies for system and user software. Maintain off-site storage of backup media for UNIX machines. Consult with the CTS Information Systems Team and/or Intelligent Transportation Systems team on future laboratory hardware needs. Basic Software - Install, update, and configure basic software packages and system software. Establish proper procedures that will detect and/or prevent any virus from infecting software. Routine updates will be done quarterly, however security patches and other time critical updates will be done immediately. Ensure that only authorized people can make changes to system and user software. Maintain software for electronic mail and user-net news. Also, ensure that major changes to system software are authorized by the laboratory manager. Plan for long-term laboratory software needs with the lab manager. * Database -Assist the ITS Team in their traffic database system implementation planning and subsequent operations support. COPIER/PRINTER POLICY The laboratory provides a copier, a black and white printer and a color printer to support the adjacent staff offices and research assistants using the laboratory. These units are not for production of multiple copies of large documents and reports. If a lab user needs such production copying, he/she should make arrangements with the PI responsible for the project. Likewise if the lab user needs special paper, envelopes, or foils for presentations, he/she should obtain them from his/her project PI. Spare toner cartridges, ink cartridges, and paper are in the cabinets supporting the units. Report printer hardware problems to the laboratory manager, report copier problems to the CTS front desk personnel, asking them to call in a problem. CTS/ITS LABORATORY ACCESS POLICY This section replicates the facility access policy and associated procedures for the Center for Transportation Studies. This facility consists of the offices, meeting rooms, laboratory, lavatories, 56

71 and library on the second floor of the Transportation and Safety Building at the University of Minnesota's Minneapolis campus. Access control is for the safety and protection of personnel and equipment. The primary access control mechanisms are the magnetic card readers at access doors and authorized magnetic swipe cards. The preferred swipe card is the individual's University ID card. In special cases, a white-pass card may be issued by CTS or the UMPD located on the first floor of TSB. The laboratory operating hours were determined after reviewing the open hours of many other on campus facilities [table 5.1]. They've been updated several times based upon user requests. Access Doors There are five pass card controlled access doors to the facility [zero uncontrolled doors]; * two for researcher/public access in the middle of the TSB 2 nd floor near the elevator, * two for staff access at ends of the TSB Skyway from the parking ramp 3 rd level, and * one for special access from the west emergency eit stairway by the classroom. These doors always allow eiting. Use of keys to open Skyway staff access doors is discouraged, janitors and police do not have keys. If a staff person unlocks any access door for class or meeting attendee convenience, that staff person is responsible for re-locking the door(s) at the meeting/session end. The ITS LABORATORY alarm system is electronically independent of the pass card door system and keys. Open Office Hours The CTS office hours are from 8:00 a.m. to 4:30 p.m. weekdays. There are no scheduled weekend or holiday hours. An electronic system unlocks the east researcher/public access doors in the center vestibule of the building at 8:00 a.m. and west door at 9:00 a.m. This same system locks both of these doors on work days at 4:30 p.m. [east] and 5:00 p.m. [west]. The alarm system on the west researcher/public access door requires disarming by the first arriving staff person or authorized researcher. 57

72 Non-Office Hours There are five pass card access privilege categories outside of open office hours: * CTS staff cards open all doors at all times. * Student support staff cards open all doors from 6:30 a.m. to 6:30 p.m. on work days only. * ITS Researcher pass cards open the west researcher/public access door and the special access stairway door only. Times are 4:00 a.m. to 11:00 p.m. work days and 8:00 am to 11:00 p.m. weekends and holidays. * CTS Researcher: Pass cards open the east researcher/public access door only. Times are 6:30 a.m. to 10:00 p.m. work days and 8:00 a.m. to 8:00 p.m. weekends and holidays. * Special: Janitors have 3 to 11 p.m. work day access through all doors. Security Services has 11 to 11:59 p.m. laboratory access via the west researcher/public access door only. Third Floor Lunchroom The lunchroom on the third floor is accessible to CTS staff during off hours without passing through the laboratory. Staff can enter the west vestibule between the laboratory and classroom from the skyway staff door then pass through the special access door into the west staircase, then return via the same route. This obviates the need for all staff having to disarm/rearm the alarm system just to use the third-floor vending machines and associated facilities. Alarm System In The Laboratory The ITS LABORATORY has implemented a door status and motion detector alarm system to provide equipment protection during non-occupied times. When armed, this system will notify the police dispatcher on the first floor of TSB within a minute of intrusion or motion being detected. A small indicator on the alarm panel(s) lights RED when the system is armed. A tone is also emitted at the control panel when a door is opened. Authorized individuals use a personal code to arm and disarm the system. * Arming: Any person with a valid code can arm the system when the panel display indicates 'system ready'. * Disarming: Any person with a valid code can disarm the system within a few seconds after entering thereby stopping the notification call. 58

73 Responsibilities: * Every Night; University Security Services arms the system every night between 11:00 and 11:59 p.m. after checking to see that the laboratory is empty. * Workdays; The first staff person or ITS Researcher to arrive on a work day is responsible for disarming the system. * Weekends and holidays; If a staff person or ITS Researcher disarms the system upon entering, he/she should re-arm the system upon leaving. * Code control; The ITS LABORATORY manager will issue personal codes to individuals who need laboratory access on weekends, holidays, or early morning. If a staff person or ITS Researcher inadvertently trips the mechanism, he/she should call the police to eplain the problem. The alarm mechanism must also be reset in this case. This reset is done by entering a valid code twice. Alarm System in The Classroom There is a detector system for the classroom, however it is not active at this time. 59

76 SECURITY SERVICES DUTIES Effective Thursday, February 1, 1996, the UMPD Security Monitor Program started providing nightly security checks of the Center for Transportation Studies. These security checks continue indefinitely until canceled by either CTS or UMPD. checks are as follows: These details for these security * The check will take place Monday through Friday, between 2300 and 2359 hours. Checks will be made on both regular business days and University holidays. The check will be completed as close to 2300 hours as possible. * One random check will be made of the area during the weekend. * The Security Monitor will check that two skyway doors and the two vestibule doors are secured. If any of these doors is found unlocked, the Security Monitor will notify the on-duty Supervisor. The on-duty Supervisor will contact the laboratory manager at home. If they are unable to contact him/her, the Supervisor will call the office administrator. If she is not available, they will contact either the CTS director or deputy director. A Security Monitor will be assigned to watch the doors until the contacted person arrives to secure the door. * The Security Monitor will check to see if the laboratory alarm indicator light is on. If it is on, they will note it on their report. This completes the CTS area security check. * If the alarm indicator light is not on, the Security Monitor will enter and patrol room 204 & 214. They will check the Identification (ID) of anyone found in this space and check names on their shift report. Authorized personnel may have guests with them. Guests must be with their authorized host. The Security Monitor will immediately call for a Police Officer if any non-guest refuses to or is unable to show ID. * If no one is working in the laboratory [room 214] the Security Monitor will arm the alarm system. * If authorized personnel will continue to work in the lab, the Security Monitor will remind them to arm the alarm when they leave. * Once each quarter, the Security Service manager will contact the laboratory manager if a new security code for the alarm system is needed. * The Center for Transportation Studies will be billed for five hours of service each week, one hour for each weekday. Charges will be billed to account number The billing contact is Cindy Holton ( ). * Questions or changes regarding this security service should be directed to John Pack ( ). 62

77 LAB MANAGER ADMINISTRATIVE DUTIES The laboratory manager has many operational responsibilities and duties to assure a quality environment for research and education.

82 FY1999 Software Planning In order to keep the ITS Laboratory at the leading edge of software technology, the support systems should be maintained and upgraded on an annual basis. The recommendations for FY1999 and the estimated costs are: Item Cost Compiler Updates --$1,500 FHWA Software package for Transportation -,$ 600** Gensym support renewal - $3,500* GIS Package Procurement (UNIX & NT) -$1,300** ISDN Software for Work Zone, TMC, & Mpls Interface -$2,500** Orbi support license renewal from IONA Technologies -$ 500** SGI license for HFRL driving simulator link to ITS lab -$1,900** Upgrade basic support software from Office 97 to Office 98; -$ 600* Upgrade NT network servers and workstations from NT4.0 to NT5.0; -$1,700* Upgrade relational database tool from Oracle 7.3 to Oracle 8.0; -$2,500** Upgrade UNIX Operating Software per University site licenses; -$ 900* TOTAL $1, * , ** , Compilers are project specific Geographic Information Systems The most common Geographic Information System (GIS) in use at Mn/DOT is the ARC/View software package. The University has a site license that can be subscribed to via the local contact. This should be obtained and installed into one of the UNIX machines and one or two of the NT machines so that various projects can have a common linking tool for their map related work. TRAFFIC MANAGEMENT CENTER INTERFACE Updates are needed to effectively demonstrate and implement the results of Dr. Michalopoulos' research projects. 68

83 > Two research assistants are working on integration of machine vision sensor data with loop detector data in the laboratory. In order to integrate with the entire suite of sensors, several things are needed: * Scope server equipment upgrade at TMC, i.e. from the NT to an NT4 Pentium computer - the lab could transfer a unit such as JUPITER. * An IP address and connection for this upgraded PC at the TMC so that it can be shared on the itslab domain. > The incident detection research has shown the capability of automatically selecting a camera source. This research would be significantly enhanced if it had two selectable video channel connections to the TMC video switch and either an RS-232 control path or an Internet control path. The laboratory has allocated two modulators in the TMC basement for this function. The highway patrol, local TV stations, City of Minneapolis, City of St. Paul, and Mn/DOT maintenance department already have this capability MACHINE VISION SYSTEM UPGRADE The Machine Vision Laboratory portions of the ITS Laboratory could use repair and selected technology upgrades as described hereunder. The ITS MVL consists of equipment installations along an freeway segment, Mn/DOT's TMC, the Minneapolis Franklin & Lyndale intersection, the University Transitway, and the University of Minnesota's Center for Transportation Studies. The MVL objective is to have a versatile traffic flow data acquisition and analysis capability to support: * developing, testing, and validating traffic flow models, * regional planning initiatives, * freeway and High Occupancy Vehicle lane comparison and safety studies, and * local congestion studies. The general MVL status is "Not Operational" although some functions and capabilities can be demonstrated at the TMC or University or City of Minneapolis Traffic Engineering Center. This section's purpose is to plan a transition from demonstration sites to an effective research support system. In order to become fully operational as an effective research tool, we need: * an effective equipment maintenance budget/plan, * replacement of some old equipment, 69

84 * a refined detector documentation and setup process, * a cohesive data collection method, and * a physical and communications infrastructure for evaluation of other nonintrusive sensor devices and associated systems. Some background information for those readers unfamiliar with previous MVL projects: Lessons Learned * The MVL configuration was documented in the March 1997 final report "Activation of the Laboratory for ITS Operational Testing (Phase I)". A Phase II report dealing with data processing is being written. m Simple intersection, ramp, and freeway mainline demonstrations are available in the ITS Laboratory. The laboratory video system infrastructure supports the MVL, reference chapter 3. m The Franklin & Lyndale intersection equipment has been integrated with the City of Minneapolis signal control system but is available for controlled and coordinated eperiments. * The University Transitway Safety project has just installed a bus/bicycle detection system and a fiber optic line that provides a partial infrastructure base for future coordinated eperiments and research. This section identifies the lessons learned by the ITS lab manager trying to operate/utilize the various pieces of the intended Machine Vision Laboratory over the last two years. Equipment and associated software can not be maintained nor operated effectively by untrained students nor by under funded, untrained, unmotivated technicians. The original MVL intention was to do all area research setup and processing at the Traffic Management Center. The advent of real time video feeds to the ITS Laboratory in 1995 raised the possibility of doing setup and processing there. In theory this is possible, in practice it isn't. Econolite, Odetics, ISS, and Peek machine vision equipment require a high quality video signal for detector setup and subsequent image processing. Video signals lose quality when they go through multiple stages of conversion and transmission, therefore the best location for machine vision processing units is at or near the camera site, avoiding multiple signal conversion stages and paths. 70

85 Lack of minimum documentation has frustrated users trying to create project plans, or to setup specific tests and eperiments, i.e.. * How high are the cameras so that new detectors can be calibrated? * What are the coverage areas of each camera? * Does the coverage of the camera set facilitate counting all vehicles entering and eiting the freeway segment or should some cameras be re-pointed or re-located? * What detector image files have been created for immediate use, where are they? * Who controls and where are detector files managed? The use PC remote control tools are ok for occasional manual file transfers or status checks but not for real-time data transfers. Fied installations such as or Franklin Lyndale may require supplemental inputs from transportable sensor systems to fully analyze flow into or out of the area. For eample, how does the Franklin Lyndale signal timing affect the northbound traffic flow turning East onto Recommendations Status update: Provide funding to have Electronic Systems Services (ESS) and Image Sensing Systems (ISS) work together to identify current system failure points and recommend repair or replacement. since 1996]. Scope server update: Attachment 1 lists the last camera status at the communication points [not checked * Install a PC as a Scope Server in the shelter - Use a laboratory Pentium PC with an eight port Digi-board. This would facilitate concurrent direct data collection from the si units and forwarding to the TMC processor * Update the TMC scope server to a Pentium to do real time processing and data forwarding to the University laboratory - Use a P-90 PC from the ITS laboratory with a four port Digi-board. 71

86 * Researcher Application Software: Create operational software for the Scope Server that will take data from all Autoscope T units concurrently, transmit it to the ITS laboratory. The laboratory software should merge it with a loop detector database for the same area. Create, verify, and document a basic set of traffic count detectors from each camera position. These will become a "default" set for individual research projects to build with. Camera update: Purchase about 6 new cameras to selectively replace some that are either obsolete or have failed and can't be repaired. Purchase several NTSC to Fiber Optic converter transmitters. Purchase several Fiber optic to NTSC converter units to fi problems from 1. AutoscopeM unit updates: * Purchase ID units to replace two in the TMC basement and si in the shelter at 1394 and Highway 100. Two immediately, the other si in a following year. Operation management: * Establish a preventive maintenance schedule to keep the hardware functioning at an acceptable level. This should include an annual funding line item for ESS at Ft. Snelling to support associated ITS research and operational test projects. * Setup periodic user training process for new students and Mn/DOT maintenance personnel or contract with a private sector company for system maintenance. * Setup a software update process * Intersection Research Capability: After the freeway system is upgraded, design and build an electronic interface to the ITS Laboratory from the Franklin and Lyndale intersection to provide real time data and video clips. * Transportable Support System: Tailor/configure an ADDCO work zone to provide real time data and video clips to the ITS Laboratory on a project by project basis. Ground rules 1. Mn/DOT ESS [Ft. Snelling] is responsible for repairing all communication equipment along I- 394 including fiber between sites. 2. Mn/DOT ESS [TMC] is responsible for repairing all fiber optic equipment located at the TMC. 72

87 3. The ITS Laboratory operations manager or his contractor is responsible for maintaining the Supervisor / Scope Server PC and the Autoscope T unit(s) at TMC and in the shed. * Maintenance access to the Autoscope T and transmission equipment in the TMC basement is limited to the hours between 9 a.m. and 3 p.m. - coordinated with Roy Christianson. * Maintenance & Researcher access to the equipment shed at TH 100 and must be coordinated with Tim Bangsund/Tom Grimes at ESS - Ft. Snelling. 4. An ITS Laboratory programmer is responsible for Supervisor [Scope Server] PC setup at the TMC as well as the RS-232 connection to the ITS Laboratory. * Researcher access to the Scope Server position at TMC is limited to weekday hours between 9 a.m. and 3 p.m. - coordinated with Ron Dahl. 5. The video - microwave system maintenance adheres to rules 3 and 4. Costs of Recommendations A complete system update is needed for quality research. Status update: Conduct tests and update the charts in Table 6.2 should about four three hour visits to the 'shed', two three hour visits to the TMC, and about 20 half hour stops at poles. Thirty hours at $50/hr (ISS Technician) + + U = -$3500. Researcher application software: Panos' current 'programmatic' research project has eperimented with a few pieces of code demonstrating data gathering method. I estimate si months of professional programmer time to transition these pieces into an operational system plus two man months of detector setup technician time for a base line traffic count system. $65,000. Camera update: Si $2,500 & four transmitter/receiver 2000 plus 2 hrs per pole installation labor is about $25,

88 Autoscope" unit updates: Two $15,000 to include 4.05 software version plus installation is about $30,000 for the TMC, shed units deferred pending completion of operational software to gather real time data. Scope server update: Allocation of two eisting laboratory P90 computers means that we need re-configuration and installation costs, about 20 is $1000, assuming that license for additional use of ISS software is donated. Add memory and NT4.0 operating system including service package 4.. Operation management: 8% of the above for s 1 ' 6 months management then $1,000/mo for maintenance for 6 months. This is identified because failure to have long term maintenance funded will cause the entire system to again fall into a state of 'not useable' for quality research. Summary of cost estimates Status Update 3, Camera Update 25, Autoscope T unit Updates 30, Scope Server Update 2, Researcher Application Software 65, Operation Management 24, TOTAL $150,
