Problems solved by technology

However, this scheme may have a green traffic light in one direction, but there are no vehicles and pedestrians in this direction; and a red traffic light in another direction, and there are vehicles and / or pedestrians waiting in this direction
As a result, the road capacity is reduced and traffic resources are wasted.

Abstract

The invention discloses a traffic signal light control method, device, equipment and medium based on digital twin, and relates to the technical field of intelligent traffic. The method includes: constructing an environment model based on digital twin technology and identifying dynamic elements located in the environment model, the environment model includes the target intersection, the upstream or downstream intersection of the target intersection, the road between the target intersection and the upstream or downstream intersection , the dynamic elements include at least one of motor vehicles, non-motor vehicles, and pedestrians; according to environmental modeling and dynamic elements, predict the number and movement direction of the target dynamic elements that will reach the target intersection at the next moment; Determine whether the original control scheme of the traffic lights at the target intersection at the next moment is reasonable; if not, generate a target control scheme, and control the traffic lights at the target intersection according to the target control scheme at the next moment. This solution can intelligently control traffic lights and improve the traffic efficiency of intersections.

Description

technical field [0001] The present invention relates to the technical field of intelligent traffic, and in particular, to a traffic signal light control method, device, device and medium based on a digital twin. Background technique [0002] With the gradual improvement of road traffic facilities and the increase in the number of private vehicles, road traffic problems are becoming more and more serious. [0003] At present, traffic lights are arranged at intersections of roads to indicate the passage of pedestrians and vehicles. The change period of traffic lights is fixed, that is, traffic lights realize periodic changes of signal lights of different colors according to a preset time interval. However, this scenario may result in a traffic signal being green in one direction but no traffic and pedestrians in that direction, and a red traffic signal in the other direction and vehicles and / or pedestrians waiting in that direction . As a result, road traffic capacity is red...
