Abstract: We use the fuzzy neural networks to solve the real time region traffic distributed control problem.The region traffic is regarded as a large scale system and the subsystems are the intersections in the region.Each intersection has its own traffic controller which manages the green phase and the phase length dynamically according to its own and its neighbor's traffic situations.The simulation shows this method has better performances in the cases of time-varying traffic patterns and heavy traffic conditions than the vehicle actuated method.
