1 Flagger Control for esurfacing or Moving Operation 5 DEVICE MINIMUM WOK AEA SET 1 SET SET 3 SET 4 ACTIVE INACTIVE ACTIVE INACTIVE SIGN SETS 1 AND 3 AE ACTIVE AND (I.E., SIGNS FACE ONCOMING TAFFIC). SIGN SETS AND 4 AE INACTIVE (I.E., SIGNS DO NOT FACE EITHE DIECTION OF TAFFIC) WHEN THE ESUFACING OPEATION IS LOCATED BETWEEN SIGN SETS 1 AND 3. SIGN SPACING FO ADVANCE SIGN SEIES () (3) WHEN SIGN SETS AND 4 AE ACTIVE, SIGN SETS 1 AND 3 BECOME INACTIVE AND AE ADVANCED TO BECOME SETS AND 4 WITH SIGN LEGENDS TUNED AWAY FOM BOTH DIECTIONS OF TAFFIC. WHEN THE ESUFACING OPEATION ADVANCES TO BETWEEN SIGN SETS AND 4, SIGN SETS AND 4 BECOME ACTIVE (I.E., NEW SIGN SETS 1 AND 3) AND SIGN SETS 1 AND 3 ADVANCED IN THE DIECTION OF THE OPEATION (I.E., NEW SIGN SETS AND 4).

CHANNELIZING DEVICES LOCATED DOWNSTEAM OF THE ONE-LANE, TWO-WAY TAPE AE OPTIONAL. THESE DEVICES SHOULD BE ELIMINATED WHEN THEI USE WILL EDUCE THE USABLE LANE WIDTH, INCLUDING ANY ACCEPTABLE SHOULDES, TO LESS THAN 10 O WILL SIGNIFICANTLY AFFECT THE ESUFACING OPEATION.
