交通流仿真是研究交通问题的有效工具．本文采用复合概率、模糊逻辑等方法建立了描述交通流中不确定性因素、车辆的到达、在路段上行驶以及通过路口的微观仿真模型，并利用面向对象的方法设计实现了一种基于上述模型的通用城市道路交通流微观仿真系统，比较真实地再现了车辆在道路网络的行驶过程．
Traffic flow simulation is an effective tool to study traffic problems. In this paper, we use the method of compound probability and fuzzy logic to establish a micro-simulation model that describes the uncertainty of traffic flow, the arrival of vehicles, the driving on the road sections and the crossing, and uses the object-oriented method to design a model based on the above model The universal urban road traffic flow microscopic simulation system, a more realistic representation of the vehicle in the road network driving process.
