摘　　要：针对交叉路口由于行车车辆多、环境复杂、容易拥堵等常导致通行效率低及易发交通事故的问题,开发了一套基于视频检测的车路协同辅助驾驶系统。对车路协同关键技术进行了讨论,基于需求分析对协同系统做了功能设计与系统框架设计以及软、硬件系统设计,并对相关设计进行说明。对所开发系统的现场初步测试验证了所设计协同系统的合理性与可行性。测试结果表明:该协同系统可有效地感知实时车辆状态信息并获取区域内道路路况信息,实现车与车、车与路之间的数据传输,综合信息分析,路况判断与信号控制,能提供良好的城市道路交通交叉路口的交通信息服务。In view of the intersection often leaded to low efficiency and traffic accidents resulted in lots of vehicles,complex environment and being easy to congestion,the paper designed and developed a vehicle assisted driving system based on video detection. It conducted a brief discussion about technology of cooperative vehicle-infrastructure system,based on the demand analysis,and made the functional design and system framework design as well as the software and hardware system design of the collaborative systems,and also explained the details for the related design. The field test of thedeveloped system demonstrated its rationality and feasibility of the designed collaborative system. The test results show that the coordination system can effectively perceive real-time vehicle state information,access to regional road traffic information,realize the data transmission of integrated information analysis,judgement and control signal among vehicle-to-vehicle and vehicle-to-road. The designed system can provide good services for the urban road traffic.
