This paper determines the coordination system pattern of traffic signal for four intersections in Cheras town at Malaysia. The data required for the study were mainly collected through video filming technique during the peak hour. Besides, the calculation and evaluation were constructed with simulation model software Traffic was used to evaluate the possible coordination of both signalized intersections. The calibration of delay, queues and journey times were practically measured. The results showed that the value of delay, journey time, and stops were reduced the before optimization from (F) LOS after optimization to (C) with performance index (PI). Simulation helps decision makers identify different possible options by analyzing enormous amounts of data. Hence, it can be used effectively to analyze traffic flow patterns and signal light timing at the traffic congestion.

Keywords: Optimization, TRANSYT, intersection, simulation, PI.
