Research on multi-agent traffic signal control system based on VANET information

In order to improve the traffic capacity of the intersection on the real road, a multi-agent traffic signal control system based on vehicular ad hoc network(VANET) is proposed in this paper. Real-time and accurate vehicle information obtained by vehicular ad hoc network is used as signal timing data source. By constructing a distributed architecture using multi-agent technology, and by realizing vehicle-road communication using communication module of intersection agent, a more intelligent signal timing strategy is constructed by discrete fuzzy controller. Through the secondary development of Vissim based on Visual Studio, we carried out the traffic simulation and comprehensive evaluation of the signal control effect under different traffic density in the road network. The simulation results are provided to demonstrate the effectiveness of the proposed signal timing strategy.
