The invention relates to an expressway ramp confluence area vehicle-road cooperative control method and system. The system comprises a vehicle-mounted subsystem, a road side unit subsystem and a cloud service subsystem. The vehicle-mounted subsystem acquires vehicle information and performs information interaction between vehicles with the road side unit subsystem; the road side unit subsystem collects state information of traffic flow and sends the state information to the cloud service subsystem. The control subsystem receives a control instruction of the cloud service subsystem and sends the control instruction to the vehicle-mounted subsystem; and the cloud service subsystem comprises a cloud server, determines an optimal confluence sequence by adopting a game playing method, and solves a control instruction adopted by each vehicle. The traffic efficiency of the whole confluence area can be improved, traffic accidents are avoided, the driving safety of vehicles is guaranteed, and energy consumption is reduced.

    本发明涉及一种高速公路匝道合流区车路协同控制方法及系统,所述系统包括车载子系统、路侧单元子系统和云服务子系统;所述车载子系统获取车辆信息,并与路侧单元子系统进行车辆之间的信息交互;所述路侧单元子系统采集交通流的状态信息,发送给云服务子系统;接收云服务子系统的控制指令,发送给车载子系统;所述云服务子系统包括云服务器,其采用博弈方法确定最优合流序列,解算出每辆车所采取的控制指令。本发明可提高整个合流区的通行效率,避免交通事故的发生,保障车辆的行车安全,降低能耗。
