Abstract

AbstractA kind of the traffic signal two-stage fuzzy control system for the single intersection was designed on the basis of analyzing the urban traffic signal control research status. The fuzzy controller determined the traffic intensity of each phase according to each lane traffic flow and the queue length, and then decided whether to extend or terminate the current signal phase. With the average vehicle delays as evaluation index to measure the control performance of the control system, the simulation of the intersection of four phases was realized using Matlab. The simulation results shown that the two-stage fuzzy control system could effectively reduce the average vehicle delay, and it was superior to the traditional timing control system and induction control system.KeywordsSingle intersectionTraffic signal controlFuzzy controllerSimulation
