摘要
提出了道路交叉口车路协调实验系统框架、实现方法并进行了系统搭建测试。在分析系统功能的基础上进行了系统逻辑框架与系统物理框架设计,实现了各子系统功能,包括:GPS车载定位信息采集、交通控制系统设定、路侧处理单元与车载处理单元程序设计与短程无线通信,在此基础上建立了道路交叉口车路协调实验系统,模拟实际交通运行状态对系统主要性能进行测试。实验结果表明该系统可以完成信号灯状态的车载实时显示,但应进一步提高定位精度与通信效果。实验系统不仅为进一步研究基于车路协调的下一代智能交通运输系统提供了实验平台,还能采集相关的车辆运行数据与驾驶员特征数据。
This paper proposed a system architecture for intersection vehicle infrastructure integration and implemented a trail system.The service content of the system was analyzed first,followed by the logical architecture and physical architecture of the system.The system components include GPS,signal controller,onboard unit,roadside unit and short-range wireless communication system.The system performance was analyzed in the test and the results show that signal indications can be effectively displayed in real time inside the vehicle.However,the accuracy of vehicle positioning and the effectiveness of the communication system can be further improved.Overall,the trial system may be used as a platform to test devices for the next generation intelligent transport system.It can also be used to collect kinematical and driver＇s data for other research purposes.
