An intersection signal control and vehicle speed guidance system in a vehicle-road collaborative environment

Abstract

The invention discloses an intersection signal control and vehicle speed guidance system in a vehicle-road collaborative environment, including vehicle-mounted equipment, roadside equipment and a signal light control module, wherein the vehicle-mounted information transmission module in the vehicle-mounted equipment acquires vehicle information and transmits it to the signal light control module , the information fed back by the signal light control module is sent to the information acquisition module; the roadside information acquisition module in the roadside equipment acquires roadside information and stores it in the intersection basic information storage module, which stores the intersection information and history in advance data, the wireless communication module wirelessly transmits roadside information, intersection information and historical data to the signal light control module; in the signal light control module, based on vehicle information, roadside information, intersection information and historical data, and uses The program model calculates the optimal timing plan information and driving suggestion information, and feeds the driving suggestion information back to the on-board equipment.

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...
