The invention discloses a signalized intersection vehicle speed guiding method based on an Internet of Vehicles environment, and belongs to the technical field of intelligent traffic. The invention aims to solve the problems that an existing signal intersection vehicle speed guiding method is limited in application scene and insufficient in attention to a traffic recovery scene under abnormal disturbance. Comprising the steps of determining a vehicle speed guide scene of a current vehicle according to a position relationship between the current vehicle and a signalized intersection, the speed of the current vehicle and the number of front queuing vehicles; according to the vehicle arrival scene, the guiding strategy is that the vehicles as many as possible smoothly pass through without stopping, and the vehicle running track is smoothed; if the current vehicle belongs to the vehicle starting scene, the guiding strategy is to accelerate the vehicle starting efficiency; and if the current vehicle belongs to the traffic recovery scene under the abnormal disturbance, the guiding strategy is to improve the traffic recovery efficiency. Fuel consumption and emission of the vehicle can be reduced through vehicle speed guiding.
一种基于车联网环境的信号交叉口车速引导方法,属于智能交通技术领域。本发明针对现有信号交叉口车速引导方法应用情景受限,对异常扰动下交通恢复情景的关注度不足的问题。包括,根据当前车辆与信号交叉口的位置关系、当前车辆速度和前方排队车辆数,确定当前车辆的车速引导情景;再给出对应引导策略:对车辆到达情景,引导策略为使尽量多的车辆不停车顺利通过,平滑车辆运行轨迹;若当前车辆隶属车辆启动情景,引导策略为加快车辆启动效率;若当前车辆隶属异常扰动下交通恢复情景,引导策略为提高交通恢复正常的效率。本发明通过车速引导能够减少车辆燃油消耗及排放。
