| 摘 要： | 通过建立交通意外事件影响下的交通流仿真模型,对拥堵传播及有效的干涉控制措施进行仿真.分析了非稳态交通条件下的车辆行为特性;并对现有主流元胞自动机模型规则进行改进,建立起一种新的元胞自动机交通流模型.该模型能够较好地仿真拥堵传播与消散过程,有效地探索拥堵的消散规律;利用该模型对各种控制措施的堵塞消散效率的研究结果表明,限流限速组合控制策略具有较优的堵塞消散效果.

| Abstract: | Accidents on expressway will disturb the normal state of traffic flow, even cause the traffic jam. To disperse effectively the traffic jam, a proper model is needed to simulate the traffic flow under crowded condition. In this paper, the characteristics of individual vehicles in the jam were studied, firstly. Then the rules of current cellular automaton model (CA model) were improved and a new CA model for the traffic jam was brought forward. With the new model, it is possible to simulate the process of tra... |
