基于车路协同的十字路口行车方案仿真研究

Simulation Research of Intersection Traffic Scheme Based on Cooperative Vehicle Infrastructure System

十字路口作为车流交汇处,交通参与者众多常引发一系列交通问题。为降低十字路口处事故发生率和提高紧急车辆在十字路口处的通行效率,基于车路协同技术,提出了面向十字路口的事故预警方案和面向十字路口的紧急车辆通行方案。在基于Veins的双向耦合车联网仿真平台上对上述两种方案进行了仿真验证。实验结果表明,应用事故预警方案可使十字路口处事故发生率降低47.5%;应用十字路口处紧急车辆通行方案可提高紧急车辆通过十字路口效率52%以上。

As the intersection of the traffic flow,the intersection has many traffic participants,which often leads to a series of traffic problems.In order to reduce the accident rate at intersections and improve the traffic efficiency of emergency vehicles at intersections,based on the Internet of vehicles technology,we put forward the early warning scheme for vehicle accidents at intersections and the traffic scheme for emergency vehicles passing through intersections.The above two schemes are simulated and verified on the Veins-based bidirectional coupled vehicle networking simulation platform.The experimental results show that the intersection accident early warning scheme can reduce the intersection accident rate by 47.5%.The efficiency of emergency vehicles passing through intersections can be increased by more than 52% with the scheme of emergency vehicles passing through intersections.
