| 摘 要： | 通过对城市交通事故影响下交通流的分析,结合元胞自动机的原理并进行了相关改进,构建了交通事故影响下车辆的跟驰模型以及变道绕行模型.此外,利用MATLAB编写仿真程序,并由仿真结果分析了在交通事故影响下车流速度的传播特点,发现障碍物对整体交通流的影响要远远超过实际上的物理范围,且影响的消散也非线性.

| Abstract: | Through the analysis of the influence of traffic accidents on traffic flow in the city,using the theory of cellular automata and improvement,vehicle-following model and lane-changing model are constructed.In addition,the MATLAB simulation program is used to analyze the feature of the influence of traffic accidents.It is that the influence to the total traffic flow by obstacle is far more than the physical range,and the dissipating is nonlinear. |
