| Abstract | This study builds three simulation models of T intersection, to analyze delay and traffic lane change rate. The arterial road has two left lanes going straight and a rightmost lane for turning right to the secondary road. Model I simulates with traffic signals applied to all directions. Model II has the arterial road with the leftmost lane always-thru traffic. Model III has two left lanes always-thru traffic, with varied channelizing island length. For all models, there is a right turn lane from the secondary road to merge the arterial road. Model I is used as a reference for discrepancy delay to Models II and III. The varied V/c ratios have been set as 0.9, 0.6, and 0.3. Also, ratios of traffic volume in the conflict directions are taken into consideration. From the simulation result, traffic management on the T intersections with always-thru traffic (Models II and III) is suitable for medium to high volume of traffic. For low traffic volume, the efficiency of T intersections is unaffected when compared to Model I. When selecting channelizing island length, traffic lane change rate should be taken into account. Longer channelizing island length can reduce lane change rate as the turning right from the secondary road to merge the traffic of the arterial road. |
