Abstract

This paper proposes a two-stage fuzzy logic controller for signal timing of an isolated intersection. In the first stage, the main phase is determined in advance, and then the controller determines the secondary phase according to the traffic flow and the queue length. In addition, the membership function is designed to adapt to the changing traffic flow. In the second stage, traffic emergency degree is calculated in real time to adjust the green time. In this case, the traffic arrival rate can be indirectly considered. Finally, the average vehicle delay is used to compare the effectiveness of each signal timing scheme. The simulation result shows that the two-stage fuzzy controller proposed in this paper can achieve good control effect.
