This study aim to contribute another solution for traffic signal design and optimal signal timing at isolated intersection based on minimizing queue length methods from effective green time and lane-area detectors (E2) from open resource software Sumo. By using real-time simulation model for single intersection in Taiwan associated with finding a suggested effective green time are to minimizing the increase in the number of queuing vehicles, maximizing throughput in one signal cycle and maximum number of vehicles can pass through the intersection without stop. Firstly, this method will find down the suggested effective green time when taking geometry and traffic flow data in the single intersection. Then, building the simulation model for both the single intersection in existing signal timing and suggested signal timing (new cycle length) are to calculate the queuing length in two models. In particular, the suggested effective green time will be detect from linear model. Moreover, the E2 is a tool of Sumo software and explain vast amount of measures such as queuing length, average time loss to compare the different between suggested simulation model and existing simulation model. Finally, this paper will illustrate and conclude the capability of this method and future work.
