Abstract: The objective of this study was to construct the supporting model for the evaluation of trafficcontrol devices at highway work zone. The National Highways No. 305 (Rangsit – Nakornnayok)was selected as an area for a case study. This study was concentrated on the effect from the trafficcontrol devices when varying the locations of traffic sign and shortening taper length. The trafficcontrol devices for this study were classified into five types as follows: 1.) an equivalent standard to the Manual on Uniform Traffic Control Devices (MUTCD), 2.) the modified MUTCD standard byvarying the location of traffic control sign No.1 (“WORK ZONE AHEAD” Sign), 3.) the modifiedMUTCD standard by varying the location of traffic control sign No.2 (“300 METERS RIGHTLANE CLOSED” Sign), 4.) the modified MUTCD standard by varying the location of trafficcontrol sign No.3 (LANE REDUCTION Sign) and 5.) the modified MUTCD standard with adjusttaper length from 90 meters to 50 meters. Each type of traffic control devices was installed athighway work zone. Traffic data including traffic volumes, average speed in both lanes weredetected. The effectiveness of each type of control devices was compared using two different ways:1) average speed of vehicle at each location in each lane, 2) speed profile pattern of vehicle in eachlane. It was found that the modified MUTCD standard by varying the location of traffic control signand shortening the taper did not effect to the speed changing pattern, but it effected the speed ofvehicle at each location in the work zone. In addition, it was observed that the traffic control signno. 3 was the most important to notify the drivers. Moreover, it was found that the speed of vehiclein closing lane in the work zone varied due to the location of traffic sign no.3. The speed increasedwhen the traffic control no.3 was moved closer to the construction area. The result can be used as aguideline for developing traffic control at highway work zone in Thailand.
