摘要
在全面分析系统功能的基础上,基于车联网技术提出了一种具有感知功能的车路协同系统的设计方案,对系统的物理框架和逻辑框架进行了设计,重点研究了各子系统的组成与功用,分析了系统的智能感知、车路协同通信和智能信息处理等关键技术。研究表明:该系统可以实时、准确地感知和采集车辆、道路环境以及全路网的交通运行状况等信息,有效实现车与车、车与路、车路与监控中心之间的数据传输,综合分析、快速判定或预测道路上的交通异常状况,并能够提供优质的交通综合服务。
With the overall analysis of the system function, a kind of cooperative vehicle-infrastructure system with sensing function is designed based on the technology of internet of vehicles. The physical architecture and the logical frame of the system are constructed with the emphasis on the sub-system composition and function. And the key technologies of the intelligent perception, cooperative vehicle-infrastructure communication and intelligence information processing are analyzed in the system. The research shows that the system can sense and collect information of vehicles, road environment and the traffic conditions timely and accurately. Thus, the data transmission among vehicles, roads and monitoring center is achieved effectively. And the comprehensive analyses, quick judgments of the traffic conditions are realized and the excellent traffic comprehensive service is offered.
