Anti-congestion fuzzy algorithm for traffic control of a class of traffic networks

A two-layer fuzzy control algorithm is proposed for traffic control of a class of traffic networks. The concerned network is supposed to have a compact central area with large traffic flow and high possibility of congestion, and a relatively large, loose outer area. The proposed anti-congestion fuzzy algorithm (ACFA) pursues two goals simultaneously, that is, to minimize the average vehicle delay and to prevent traffic congestion from happening. The simulation included in the end shows the performance of the proposed approach is better than that of Green Link Determining (GLIDE) in case of large traffic volume.
