摘要
针对道路交叉口处交通流复杂、事故频发,及现有事故预警系统成本较高的问题,设计了一种基于VANETs的交叉口车辆碰撞预警系统。首先,结合交叉口场景搭建了碰撞预警系统的体系架构,设计了系统的工作流程;然后,给出了车辆碰撞的检测方案和不同危险等级的消息发布方案;最后,在分析了不同碰撞预警系统影响因素的基础上,从影响因素和系统有效性两方面,对系统的性能进行了仿真测试。测试结果表明,系统能够较为准确的完成事故检测和预警。
Aiming at the complex traffic flow,frequent accidents and high cost of the existing accident warning system at the intersection scenario,designed a vehicle collision warning system based on VANET.Firstly,built the collision warning system architecture based on the intersection scene,while put up with the workflow of the system.Then,proposed the detection scheme of vehicle collision and the message broadcast scheme of different danger levels.Finally,based on the analysis of the impact factors of collision warning systems,tested the performance of the system by simulation platform Veins.Results show that the system can complete accident detection and warning accurately.
