| 摘 要： | 模拟交通冲突是道路交通微观仿真中的实现难点。该文描述了由于机动车辆对固定冲突点竞争而引起的“死锁”现象,分析了这种现象的产生机理。在评述现有解决方法的基础上,结合交通冲突的方式和固定冲突点的分布情况,给出了死锁模型和典型情况下预防死锁的算法,同时设定时间参数和车流量参数以便进行路口通行能力评价。最后针对有交通信号控制的十字路口进行仿真编程实现,仿真结果表明本算法对于机动车辆在固定冲突点的死锁预防是可行的,仿真效果与实际的车辆走行情况相吻合。

| Abstract: | Traffic conflict simulation is a knot in the microscopic simulation of road traffic.This paper describes the deadlock phenomenon caused by motor vehicles competing to fixed conflict points,and analyzes the mechanism of it.After reviewing the existing solutions and considering traffic conflict mode and the distribution of fixed conflict point,a deadlock model and algorithm under typical conditions are given.The time parameter and traffic flow parameter are also given so that the traffic capacity can be assessed.Then the algorithm is realized under an intersection with traffic signal control.It shows that this algorithm is available and the effect of simulation matches the characters of running of vehicles. |
