The invention provides a control method applied to signal intersection vehicle speed guidance in a vehicle-road cooperative mixed traffic environment, relates to the technical field of intelligent traffic, and aims to solve the problem that mixed traffic flow cannot effectively guide vehicle speed so as to realize the purpose that vehicles are stopped to pass through signal intersections as little as possible. Firstly, an intelligent intersection control system is established, and road section partition design is carried out; a single vehicle is used as a research unit, and a specific speed guiding red light/green light traffic scene is constructed according to a signal state, vehicle information and the like when a networked vehicle enters a guiding area so as to judge a driving operation behavior to be executed; secondly, a plurality of vehicles are used as research units for formation, and a multi-vehicle speed cooperative guide control process is provided; and finally, calculating the speed of the target guiding vehicle, and providing an optimal safe driving vehicle speed interval for a driver. The signal intersection vehicle speed guiding method in the vehicle-road cooperative mixed driving environment can be suitable for conditions of different traffic flow densities and different network connection vehicle permeability, and the passing efficiency can be effectively improved.
本发明提供一种应用于车路协同混行环境下信号交叉口车速引导的控制方法,涉及智能交通技术领域,针对混行交通流无法有效引导车辆速度,进而实现尽少停车通过信号交叉口。首先建立智能交叉口控制系统,进行路段分区设计;以单车为研究单元,根据网联车辆进入引导区域时信号状态、车辆信息等,构建具体速度引导红灯/绿灯交通场景,来判断应执行的驾驶操作行为;其次,以多车为研究单元进行编队,提出一种多车车速协同引导控制流程;最后,计算目标引导车辆速度,为驾驶员提供最优安全行驶车速区间。所述车路协同混行环境下信号交叉口车速引导方法,可适用于不同车流密度、不同网联车辆渗透率条件,能够有效提高通行效率。
