Intersection signal control and speed guidance system in cooperative vehicle infrastructure environment

Abstract

The invention discloses an intersection signal control and speed guidance system in a cooperative vehicle infrastructure environment. The system comprises on-board units, a road side unit and a signallight control module, wherein an on-board information transmission module in each on-board unit acquires vehicle information and transmits the vehicle information to the signal light control module,and the information fed back by the signal light control module is sent to an information acquisition module; a road side information acquisition module in the road side unit acquires road side information and stores the road side information into an intersection basic information storage module, the intersection basic information storage module pre-stores intersection information and historical data, and a wireless communication module wirelessly transmits the road side information, the intersection information and the historical data to the signal light control module; and in the signal light control module, optimal timing scheme information and travel advice information are obtained through calculation by use of a program model in the signal light control module based on the vehicle information, the road side information, the intersection information and the historical data, and the travel advice information is fed back to the on-board units.

Description

technical field [0001] The invention relates to the field of intelligent traffic signal control, in particular to an intersection signal control and vehicle speed guidance system in a vehicle-road collaborative environment. Background technique [0002] The basic idea of ​​Cooperative Vehicle Infrastructure System (CVIS) is to use multidisciplinary cross-integration methods, make full use of new technologies such as network communication and parallel computing, and realize the communication between vehicles and traffic control equipment, and between vehicles and vehicles. The intelligent coordination and cooperation of the system can achieve the goal of optimizing the utilization of system resources, improving road traffic safety, and alleviating traffic congestion. [0003] Intersections are the bottleneck of road network traffic capacity and affect road network traffic efficiency. In the vehicle-road collaborative environment, it is particularly important to realize the c...
