Traffic control method and device for road network, storage medium and management equipment

Abstract

The application, which belongs to the field of intelligent traffic, provides a traffic control method and device for a road network, a storage medium and management equipment. The method comprises thefollowing steps: reducing the possibility of congestion of a target road network, acquiring a target OD flow in a to-be-predicted time period; acquiring a plurality of key paths between a main traffic occurrence point and a main traffic attraction point in the target road network; acquiring a plurality of preset shunting proportions of a plurality of pre-stored key paths; for each preset shuntingproportion, determining the total vehicle adjustment amount of a bottleneck road section on each key path; determining a green signal ratio of a signal lamp in a target driving direction of each controllable road section corresponding to each bottleneck road section; and then determining actual shunting proportions of the plurality of key paths in a preset duration starting in the to-be-predictedtime period, selecting a green signal ratio corresponding to the preset shunting proportion closer to the actual shunting proportion, and controlling the signal lamp in the target road network basedon the green signal ratio. According to the invention, the possibility of congestion can be reduced.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to a road network traffic control method, device, storage medium and management equipment. Background technique [0002] With the improvement of people's living standards, people buy cars as a means of transportation, and traffic congestion becomes one of the main problems faced by cities. [0003] In related technologies, when dealing with traffic congestion, it is generally to obtain the traffic flow information on the current road, then determine the road congestion based on the obtained traffic flow information, and then set the VMS (VariableMessage Sign, variable information sign) on the road. board) shows congestion on nearby roads. For example, green is displayed in the display area corresponding to a certain road, indicating normal traffic, and red is displayed in the display area corresponding to a certain road, indicating severe congestion, etc. People can choose travel...

Problems solved by technology

[0004] Since the congestion situation is only displayed for people's reference, no measures have been taken, so the traffic congestion cannot be fundamentally alleviated
