摘要： Cellular automaton traffic models can include various .factors in traffic systems and the corresponding conutational simulations are rather simple and effecive, The Billam-Middleton model (BML model facilitates the simulation of twodimensional traffic flow problems via the cellular automaton models. In this paper, the BML model is improved by removing its limitation of syncronized change of trafficlights. In the new model, the traffic light at each crossing could arbilrarliy, change its starting time and tempo of variution, and hence thc model more more realitically describe the influence of traffic lights on the performance of traffic systems. Some new effects appearing in the new nodel are also elucidated.
