摘　　要：基于Petri网理论,提出一种对十字路口交通控制系统建模和性能评估的方法。该方法根据路口间的交通流量,计算在不同红绿灯相位差的情况下,各个路口的平均等待队列长度和平均等待时间,从而得出最优的红绿灯相位差。与通常的Petri网模型相比,该模型减少了分析的复杂性,提高了城市路网的通行能力。This paper proposes a method of modeling and performance analysis of traffic control system based on the theory of Petri net. This method figures out the average length of waiting queue and the average latency time of each intersection to pick out the most superior offset according to the traffic flow and different offsets of the traffic lights at intersections. This model greatly reduces the complexity of analysis, and improves the transportation capability of urban traffic networks compared with accustomed Petri net model.
