| 摘 要： | 采用细胞自动机方法研究了在单向道路上行驶的2辆不同性能(加速度能力、最大速度等)车辆的运动状态和相互关系,以及性能参数对行驶状态的影响.讨论了在设置路口和信号灯的情况下,不同信号灯控制策略(信号灯的时间周期及绿信比)对车辆运动状态的影响.细胞自动机方法通过JAVA编程进行数值模拟,得到车辆行驶时间-位置之间的关系,结果与预期相同.该模型退化为匀速运动状态情形时,所得结果与近期文献的结果相一致,也证明了文中所用方法的可靠性和合理性.

| Abstract: | According to the theory of the Cellular Automata(CA),this paper has proposed a vehicular movement model.Based on numerical simulation via JAVA program,the time-position relation of vehicular movement states has been obtained.The interactions of two vehicles with different performances(acceleration ability and maximum allowable velocity),as well as the influence of the performance parameters on the movement states are studied.The crossroads and traffic signals are also considered in this model,and the effect... |
