Abstract:

With the development of cooperative vehicle infrastructure technology, advanced communication methods such as optical fiber, Beidou, 5G, and C-V2X are being used in the transportation field. In order to improve the level of road service and ensure traffic safety, the processed information of road, environment, traffic, and management is transmitted to traffic participants by various means such as variable information signs, traffic broadcasts, and on-board units. This article analyzes and summarizes three types of application scenarios with strong public experience, including urban intelligent connected buses, safety warnings at non-signal controlled intersections of ordinary national and provincial roads, and smart expressway application scenarios. It also summarizes and looks forward to the future development and application of vehicle road collaboration technology.

Key words: general cooperative vehicle infrastructure, intelligent connected bus, safety warning for non-signal controlled intersections, smart expressway
