| 摘 要： | 针对发生事故的双车道模型,考虑行驶车辆是否在事故车道以及距离事故的远近,分析不同区域的换道特点,建立双车道元胞自动机模型。在开放边界条件下,改变进口车辆的驶入率和事故的持续时间,得到了车流量和平均车速的变化曲线,结果表明,在发生交通事故时应缩短事故处理时间,并将入口车辆进入率降至一定值。

| Abstract: | A two-lane cellular automaton model was established under the traffic accident. Considering whether the vehicle is in the accident lane and the distance from the accident, different characteristics of lane change were analyzed. In the open boundary conditions, traffic flow, density and average speed were analyzed by changing the entry rate of the imported vehicles and duration of the accident. The results show that the accident processing time should be shortened and the entry rate of vehicle should be reduced to a certain value in the case of traffic accidents. |
