基于专用短程通信技术DSRC的智能车路协同系统设计与实现

Design and Implementation of Cooperative Intelligent Transport Systems (C-ITS) Based on Dedicated Short Range Communications (DSRC)

针对交通安全问题,智能车路协同系统的设计与实现可大幅减少交通事故,提高交通运行效率。本文采用新一代专用短程通信和互联网技术,基于车车、车路通信实现实时信息交互和共享,将人、车、路有机协同,设计并实现一套新型的智能车路协同系统。该系统可提高交通安全水平,提升道路通行效率,降低能源消耗,是继安全带、安全气囊之后的新一代安全技术,能有效的弥补高级驾驶辅助系统的不足,在保障道路交通安全方面将发挥巨大作用。路试场测试结果表明:基于车路协同系统的实验车辆,能提前接收到预警消息,可大大的降低了交通事故的发生率,该系统具有广泛的应用前景。

Cooperative Intelligent Transport Systems （C-ITS） can significantly reduce traffic accidents and im- prove traffic efficiency. This paper designs and develops a new type of C-ITS based on the dedicated short range com- munications （DSRC） and internet technology. C-ITS technology has the potential to allow vehicles and surrounding infrastructure to exchange and share information. This technology expected to improve traffic management, reduce traf- fic congestion and pollution, assist in driver decision-making. The test results in testing ground show that the experi- mental vehicle, based on C-ITS technology, can receive warning message in advance and avoid road crashes. The sys- tem can be widely used in different scenarios.
