近年来,车联网和车路协同在我国得到了大力发展,同时如何将车联网及车路协同与传统交通控制及优化相结合是现在面临的主要问题。为了解决现状车联网及车路协同所面临的问题,需根据车辆间、车辆与交叉口控制单元间的通信,构建以最优车速为目标函数,车辆通过信号交叉口的车速引导模型,以减小信号交叉口的平均延误和排队长度,从而使靠近交叉口的车辆更准确的获取前方的信息,提升车联网环境下的信号交叉口整体运行效率。
In recent years, car networking and roadway coordination have been greatly developed in our country. At the same time, how to combine vehicle networking and roadway coordination with traditional traffic control and optimization is the main problem nowadays. In order to solve the problem of vehicle interconnection and vehicle coordination, the vehicle speed guidance model with the optimal vehicle speed as the objective function and the vehicle passing the signalized intersection should be constructed according to the communication among vehicles, vehicles and control units at intersections Average delay and queue length of small signal intersections, so that vehicles near the intersections can obtain more accurate information in front of them and improve the overall operation efficiency of the signalized intersections in a car networking environment.
