Urban plane intersection fuzzy control and simulation

Traffic signal control has become one of the most important topics in this era. Considering the current situation of urban traffic signal control, a single intersection two-stage fuzzy control system is proposed in the paper. The first stage consists of the green light phase traffic intensity module and the red light phase traffic intensity module, the second stage is the decision module. The controller can analyse and estimate traffic situation through gathering the sensor data, determine whether the current signal phase should be extended or terminated. The simulation procedure has been developed by matlab, in contrast, under the same condition, an actuated control method is used in intersection, procedure is also been written. Result of comparison shows that the performance of the two-stage fuzzy method is better than the traffic actuated control, two-stage fuzzy method can decrease vehicle average delay effectively.
