Vehicle-Road Cooperative Systems aim to achieve 'dialogue' between vehicles and between vehicles and roadside devices. Vehicle-Road Cooperation has become an important subsystem and development direction of Intelligent Transportation Systems (ITS), providing technical support for vehicle-road cooperative control, proactive traffic safety, intelligent public transportation, vehicle networking systems, etc. (1) Supports various proactive safety experiments: By integrating DSRC and 3G wireless technologies, it supports communication between vehicles and between vehicles and roads at the basic level for various proactive safety experiments, such as intersection collision avoidance systems, construction zone warning systems, two-way passage assistance systems in difficult areas, speed guidance systems, etc. (2) Supports data collection and analysis in a vehicle-road cooperative environment: It supports the collection of on-site traffic and road environment data in various communication modes and real-time transmission to the control center; it also supports the use of RFID technology for traffic status and event collection. (3) Supports real-time online vehicle-road cooperative simulation: By docking with the control laboratory, real data can be obtained from the site for model calibration. At the same time, through closed-loop control, the results of simulation optimization are fed back to the field system in real time.
