The invention discloses a traffic line guiding and signal optimizing system based on vehicle-road cooperation. The system comprises a vehicle-mounted display terminal, an intersection gathering terminal and a line guiding and optimizing system background; the vehicle-mounted display terminal communicates with the intersection gathering terminal through wireless networking; and vehicle informationuploaded by the intersection gathering terminal has two optimization modes in total, is displayed through a part of a map of the vehicle-mounted display terminal, and intersection signal timing is optimized, so that vehicles can reach preset destinations within the expected time or under the condition that consumed time is short; the timing optimization is divided into three sets of optimization schemes: dynamic green wave, overflow control and full-dimensional optimization. Original monitoring equipment such as a forward radar and a video vehicle detector at an intersection is replaced by real-time data uploaded by the vehicle-mounted terminal, the conditions of road vehicles are accurately known in real time; the system is matched with an optimization algorithm and a line guiding function, so that the problems of congestion of a main road, fewer vehicles at surrounding road sections and waste of road resources are solved.
本发明公开了一种基于车路协同的交通线路引导和信号优化系统,包括车载显示端、路口汇聚端、线路引导和优化系统后台,所述车载显示端利用无线组网与路口汇聚端进行通讯,所述路口汇聚端上传的车辆信息共有两种优化方式,通过车载显示端下部分地图来进行显示,并通过优化路口信号配时让这些车辆可以在预计时间内或者耗时不长的情况下到达预定目的地;配时优化分为三套优化方案分别为:动态绿波、溢出控制和全维度优化。通过车载端上传的实时数据,替代了路口原有的监测设备如正向雷达、视频车辆检测器,实时精准的了解道路车辆状况,系统配合优化算法和线路引导功能,解决了主路拥堵,周围路段车辆较少,浪费道路资源的问题。
