Evaluation of U-turn Manuvers on suburban signalized intersection's Perfomances under suburban's traffic condition
Author(s):
Abstract:
The study of the characteristics of traffic flows at intersections is one of the effective measures necessary to improve the streets levels of services and properly understand the drivers traffic performance. SubUrban signalized intersections are among the spots with heavy traffic and flow. Therefore, optimization of traffic flow in such spots is an inevitable action.
One of the most important rotational movements in intersection is U-turn maneuvers. The aim of the present study is to analyze the effect of U-turn maneuvers on suburban Signalized intersections performance. For this purpose, a network which located near Tehran was modeled and simulated with Synchro. Softwares parameters were calibrated to the extent possible under the circumstances of Tehran. The results show that if U-turn maneuver eliminated from suburabn signalized intersection, intersections Measure of effectiveness such as queue length, V/C ratio and delays will be reduced, also intersections level of service will be improved. Simulation results on the second suburabn signalized intersection also confirmed the accuracy of the work.
