2 TranSync-M is a mobile tool for real-time diagnosis and evaluation of coordinated traffic signal plans About TranSync-M TranSync-Mobile is the first mobile tool for real-time diagnosis and evaluation of coordinated traffic signal timing plans (U.S. Patent pending). It enable users to develop virtual signal controllers on their mobile devices, which run the same timing plans as that running in the field. Together with its advanced features of geo-referencing and dynamic time-space diagram, it allows users to quickly diagnose common signal timing issues such as wrong offset and erroneous controller clock sync, and to identify causes of unintended coordination synchronization failures or loss of coordination. At A Glance Mobile tool that can be installed in iphone and ipad Virtual signal controllers running true signal timing plans in real-time Dynamic time-space diagram Accurate recording and reply of vehicle movements and trajectories Automatic map-matching and georeferencing Easy-to-use user interface Data transfer with TranSync-D, the desktop software for comprehensive signal management and optimization

3 Signal Timing Diagnosis Interface Traffic signals are prone to loss of coordination. The causes are manifold, which include but are not limited to: signal controller clock not synchronized with other signals in the system; wrongly coded signal timing plan such as the offset and phasing sequence, and signal transition after preemption by emergency vehicles. TranSync-M enables users to quickly identify problems by referring to the original signal timing plans stored in the portable mobile tool, thus greatly reduces the workloads of traffic engineers who are responsible for routine operation and maintenance of traffic signals. Relation with TranSync-D TranSync-M can be used as a standalone tool or together with TranSync-Desktop, a windowsbased software product for system management of traffic signals and optimization of coordination plans. While TranSync-M provides traffic engineers with the flexibility of real-time diagnosis and evaluation of signal coordination plans, TranSync-D is a powerful signal management tool with combined functions of optimization and data management. The data are transferrable between TranSync-D and TranSync-M. Taking advantage of the advanced features of a mobile device, TranSync-M allows users to input and edit signal timing data and transportation agency s information directly from the touch screen. For example, a signal timing plan can be easily edited through such operations as sliding, touching, and dragging. Performance Examination Another common problem with traffic signals is the outdated timing plans that do not keep up with the change of traffic flow patterns. It s suggested the signal timing plans be examined and retimed regularly. When newly updated signal timing plans are implemented into the field, traffic engineers need to put enormous efforts to collect measurement data such as delay and queue length from the field for the before and after analysis. TranSync-M makes this routine task rather easy by requiring only a couple of field runs with the mobile device on board, and before and after studies can then be conducted by simply using the vehicle trajectories collected from the field.

4 Large Database TranSync-M can store and process large amounts of traffic signal timing data in one single mobile device. Virtual Controller Each signal runs in realtime the same signal timing plans as that run in the field controllers. TranSync-M demonstrates in both standard doublering format and graphical illustration the real-time signal timing information on the mobile device.

Signal timing plans can also be transferred directly from TranSync-D.

5 Signal Timing Editor The Signal Timing Editor allows users to manually input and edit signal timing plans and view the signal parameters through the double-ring diagram. Signal timing plans can also be transferred directly from TranSync-D. Map Viewer The map viewer is designed to collect and process the coordinates of the intersections and show their locations on the digital map of the mobile device. It also allows for editing signals directly from the map view window.

Dynamic Time-Space Diagram TranSync-M automatically creates time-space diagrams once signal timing plans are correctly coded into the device.

This way, the information of each signal s local clock, current active phase, and the time remaining in the current phase can be demonstrated in an integrated interface

6 Dynamic Time-Space Diagram TranSync-M automatically creates time-space diagrams once signal timing plans are correctly coded into the device. One of the most advanced features of TranSync-M is the emulation of real-time signal timing status on top of the time-space diagram. This way, the information of each signal s local clock, current active phase, and the time remaining in the current phase can be demonstrated in an integrated interface along with the time-space diagram. Video Recorder Using the built-in camera of a mobile device, TranSync-M allows users to take real-time videos and synchronize the before-and-after video clips into one view afterwards for detailed analysis.

7 Performance Measurement Viewer To facilitate before-and-after analyses, the field recorded traffic conditions are synchronized and integrated with the dynamic time-space diagram and vehicle trajectories and all these information can be viewed in one window.
