摘要
为提高城市道路无信号交叉口车辆的安全通行效率,基于车路协同技术体系提供的数据环境,采集车辆位置信息和运动状态信息,分别提出针对同向车流和异向车流的车速引导方法,搭建无信号交叉口车辆的车速引导模型,在避免交叉口冲突的同时,提高车辆通过交叉口的行车效率。利用VISSIM和Python设计联合仿真进行验证,结果表明,相比于传统无信号控制,提出的车速引导方法能够有效降低车辆的行程时间和停车次数,提高城市道路时空间资源的利用效率。
In order to improve the safety efficiency of vehicles at unsignalized intersections in urban roads,the speed guidance method of vehicles for the same direction of traffic flow and different direction of traffic flow is proposed respectively,and the speed guidance model of vehicles is built to avoid intersection conflicts and improve the driving efficiency of vehicles through collecting location information and motion state information of vehicles with the help of data environment provided by CVIS.Based on VISSIM and Python,the co-simulation is designed to verify the results.The results show that compared with the traditional non-signal control,the proposed speed guidance method can effectively reduce the travel time and stop times of vehicles,and improve the utilization efficiency of urban road space resources.
