Traffic time period control method for improving traffic efficiency of adjacent intersections of main roads

Abstract

The invention discloses a traffic time period control method for improving the traffic efficiency of adjacent intersections of main roads. The method comprises the following steps: on the basis of traffic demand distribution information of urban main roads, obtaining main road traffic demand OD information of different time periods each day through the multi-source data analysis technology, obtaining traffic demand amounts, real-time vehicle arrival rates and vehicle queue lengths of entrance lanes of adjacent intersections to be optimized of the main roads during different time periods, andtaking the sum of all OD amounts of all directions of the entrance lanes of the intersections within a certain time period as the traffic demand amount of the direction within the time period. According to the traffic time period control method disclosed by the invention, the signal control of the entrance lanes of the adjacent intersections is optimized based on the historical data traffic information, so that the occurrence of the decline of the traffic capacity of the adjacent intersections can be prevented more effectively, the occurrence of traffic congestion is avoided, the traffic efficiency of the intersections is maximized, the control method is easy to implement, and the traffic time period control method has a wide application range and a good application prospect.

Description

technical field [0001] The invention relates to the technical fields of traffic control and intelligent traffic, in particular to a traffic time period control method for improving traffic efficiency at adjacent intersections of trunk roads. Background technique [0002] Signal light control Intersection traffic signal control makes left-turn vehicles and straight vehicles, vehicles and pedestrians stagger in passing time when the right-hand system is made, and is generally used at the intersection of busy urban branch roads and arterial roads or at the intersection of arterial roads and arterial roads. The entrance part of the intersection controlled by signal lights is widened, and the entrance lanes are divided into three directions of turning left, going straight, and turning right, increasing the number of lanes, and can greatly improve the traffic capacity of vehicles. [0003] Urban arterial roads are the roads that connect the traffic of major parts of the city. They...

AI Technical Summary

Problems solved by technology

[0003] Urban arterial roads are the roads that connect the traffic of major parts of the city. They are mainly used for traffic functions and are responsible for the main passenger and cargo tasks in the city. They are the skeleton of the urban road network. The width of the roadway should be set according to the size of the traffic flow. There should be as few road intersections as possible, and the traffic efficiency of adjacent intersections on urban arterial roads directly affects the traffic conditions between the main road and each intersection. Existing urban arterial roads are mostly controlled by preset traffic lights at adjacent intersections , it cannot prevent the decline of the traffic capacity of adjacent intersections, it is easy to have traffic jams in certain periods of time, and it is impossible to maximize the traffic efficiency of intersections
