摘 要：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

Dong Jinwei Yuan Shoutong Hu Xin

Abstract：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， artificial 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 traffic safety. The goal is to optimize the use of system resources and alleviating traffic congestion to form a safe， efficient， and environmentally friendly road traffic system. The pilot area is generally located in an area with a large traffic 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.

Key words：demonstration area， cooperative vehicle infrastructure， road intersection， wireless communication

1 前言

隨着新一代无线通信技术、高精尖制造技术、人工智能技术的发展，我国车路协同技术产业进入快车道，技术创新日益活跃，新兴行业与技术的发展，产业规模不断扩大，但也存在相关核心技术有待提高、产业生态尚需完善以及政策法规亟待完善等问题。一是技术核心产品还未完全达到落地水平，车路协同核心产品如车载设备芯片、车载终端、路侧基础通信设备等在我国虽已获得巨大进展，但产品本身离商业化的部署还有较大的距离。二是车路协同商业运作模式尚不清晰，拓扑网络部署方案不明确，还由于车路协同涉及的产业链较长，上下游相关的不同行业厂商众多，目前尚未形成强有力的行业主导方，整体未有统一的网络部署方案，缺乏核心凝聚力与竞争力，产业推动力量发散。……
