智能网联先导区道路交叉口车路协同系统设计

近年来,车路协同是汽车与交通行业发展的重要方向之一,而车路协同环境建设和推广也成为先导区建设的重中之重。车路协同系统利用无线通信、传感器检测、高精度地图定位、人工智能、计算机等众多技术来获取车辆和道路信息,在实现人、车、路充分协同的同时,从而达到主动提高道路交通安全、最优化利用系统资源、缓解交通拥挤的目标,形成安全、效率、环保的道路交通系统。先导区一般选址在车流量大、道路环境复杂、附近居住人口密集的区域。先导区内汽车智能与网联化测试、V2X场景实现均需要借助于车路协同系统环境。本文介绍了先导区道路交叉口车路协同系统涵盖的技术,以及实现的功能和信息服务场景,并从车端、路端给出了相应场景的解决方案。

Design of Vehicle Road Coordination System for Intelligent Network Leading Area Road Intersection

In recent years,vehicle-road coordination has been one of the important directions for the development of the automobile and transportation industries,and the construction and promotion of the vehicle-road coordination environment has also become the top priority in the construction of the pilot zone.The vehicle-road collaboration system uses wireless communication,sensor detection,high-precision map positioning,artifi cial intelligence,computers,and many other technologies to obtain vehicle and road information.While achieving full collaboration between people,vehicles,and roads,it can actively improve road traffi c safety.The goal is to optimize the use of system resources and alleviating traffi c congestion to form a safe,effi cient,and environmentally friendly road traffi c system.The pilot area is generally located in an area with a large traffi c volume,a complex road environment,and a densely populated area nearby.In the pilot area,vehicle intelligence and networked testing,and the realization of V2X scenarios all require the aid of a vehicle-road collaborative system environment.This article introduces the technologies covered by the vehicle-road collaboration system at road intersections in the pilot zone,as well as the realized functions and information service scenarios,and provides solutions for the corresponding scenarios from the vehicle and the road.
