Abstract: Traditional traffic signal control methods lacked the flexibility on phase and phase sequence，and their traffic efficiency and control of real-time was poor.To solve these problems，a self-organizing control method for urban traffic signal based on the pass-priority rules was proposed.In the self-organizing control system for urban traffic signal，the average delay time，the average speed and the parking rate were taken as evaluation indices，and the pass-priority rules (including pass-priority，intersections relation and phase combination) were taken as fundamental basis of the real-time control on phase and phase sequence.Therefore，a microscopic city traffic model based on cellular automata (CA) was established，which efficiently realized the self-organizing control of traffic signal.The traffic control simulation of 16 intersections under the same condition shows that：comprising with traditional fixed-time control and inductive control methods，the self-organizing control method for urban traffic signal based on the pass- priority rules has higher traffic efficiency and better real-time control effect.The proposed method based on the pass-priority rules is a theoretical exploration to the self-organizing control for urban traffic signal，and it has a guidance meaning to the engineering of the new generation of intelligent traffic control equipment and system.
