The invention discloses a traffic light bus priority system applied to the Internet of Vehicles. The system comprises a bus provided with an on-board unit (OBU), a road side unit (RSU) and a signal control machine, when the bus is about to arrive at the intersection, the OBU receives intersection map information sent by the RSU, determines intersection steering information according to the intersection map information, and sends vehicle basic state information to the RSU; the RSU processes the received basic state information of the vehicle, generates corresponding priority request information and sends the priority request information to the signal controller; and the signal controller optimizes an intersection signal timing scheme according to the priority request information and the current signal state, so that the bus passes according to the optimized intersection signal timing scheme. Real-time information interaction between the bus and the intersection signal control machine is achieved through the OBU, the RSU and the signal control machine, the signal control machine optimizes and controls the intersection signal timing scheme according to the priority request information to enable the bus to pass preferentially, and the waiting time of the bus at the intersection is shortened.
本发明公开了一种应用于车联网的红绿灯公交优先系统。其中,该系统包括:配置有车载单元OBU的公交车、路侧单元RSU以及信号控制机;当公交车即将到达交叉路口时,OBU接收RSU发送的路口地图信息,根据路口地图信息确定路口转向信息,向RSU发送车辆基本状态信息;RSU对接收到的车辆基本状态信息进行处理,生成对应的优先请求信息发送给信号控制机;信号控制机根据优先请求信息、当前信号状态优化路口信号配时方案,以使公交车根据优化后的路口信号配时方案进行通行。本发明通过采用OBU、RSU和信号控制机来实现公交车和路口信号控制机的实时信息交互,信号控制机根据优先请求信息来优化控制路口信号配时方案让公交车优先通行,减少公交车在路口的等待时间。
