Abstract

The invention discloses a vehicle-road cooperative control system of a signal lamp intersection. The vehicle-road cooperative control system is composed of a roadside system, a vehicle-mounted systemand a cloud data interaction system. The roadside system consists of a signal lamp data acquisition module, a traffic event detection module, a signal lamp timing module and a roadside communication module and is used for collecting signal lamp state information of an intersection under jurisdiction in various directions regularly and collecting traffic event information of the intersection withina certain range. The vehicle-mounted system matches map data of the cloud data interaction system based on location information, searches for signal lamp information and traffic accident informationof the intersection automatically, and sends the processed information to the vehicle-mounted display module for displaying. The cloud data interaction system is used for receiving signal lamp state information and traffic event information of different intersections, carrying out fusion with map data of corresponding intersections, carrying out broadcasting, and modifying signal lamp timing plansof the corresponding intersections dynamically according to intersection traffic information. Therefore, the driving safety and passing efficiency of the intersection are improved; and the emission is reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a vehicle-road cooperative control system at a signal light intersection, especially suitable for multiple consecutive signal light intersections. Background technique [0002] With the increase of urban car ownership, problems such as traffic congestion, energy consumption, and driving safety have become increasingly prominent. In actual traffic, an important factor that causes traffic congestion and increases fuel consumption is the low efficiency of traffic lights at intersections. When a vehicle passes an intersection, it may encounter red lights frequently, and the vehicle will stop and start frequently, causing the engine to work in the high energy consumption and high emission range for a long time. On the other hand, intersections often appear congested in one direction and very smooth in the other direction, which affects the overall traff...
