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.
