Distributed and coordinated traffic signal control approach based on multi-agent system

After constructing a BDI model of traffic signal control agent, this paper proposes a distributed multi-agent-based coordinated traffic signal control method. Through exchanging messages and cooperating between signal control agents in adjacent intersections, does the control agent's best to let the vehicle fleet from adjacent junction pass the local intersection without stop while guarantees the utility efficiency of the time of green light in the local junction at relatively high level. After programming a microscopic simulation program of traffic control, this paper simulates several different signal control methods in a traffic network consists of eight junctions. The result of simulating illustrates that the effect of the new signal control approach is obviously better than the traditional fixed-time control approach and actuated control approach.
