摘要
由于无法对交叉口车辆左转的各种控制策略进行实地测评,在提出了交叉口车辆左转运动轨迹模型的基础上,建模了两种主要的车辆左转避撞行为。采用C#语言设计开发了交叉口微观交通仿真系统,实现了车辆在交叉口左转避撞行为的动态模拟和分析。结果表明不同交通需求状况下合理设置左转避撞行为可以有效降低车辆平均延误时间、车辆启停次数等指标适合于不同交通控制策略的模拟和评价。
The various control strategies of left-turn vehicle in intersection couldn' t be evaluated on field, this paper proposed the model of left-turn vehicle trajectory in intersection, then modeled respectively two main types of left-turn vehicle collision a- voidance behavior. It developed an intersection microscopic traffic simulation system by using C# language to simulate and ana- lyzed the collision avoidance behavior. The results show that a reasonable set of collision avoidance behavior in different traffic demands can effectively reduce the average delay time, start-stop times and other indicators of vehicle. The system is suitable for the simulation and evaluation of different traffic control strategies.
