Pavement signal lamp control method between adjacent intersections based on particle swarm algorithm

Abstract

A pavement signal lamp control method between adjacent intersections based on a particle swarm algorithm is disclosed. The control method comprises the following steps that 1) division is performed through referencing time periods of historical traffic data; the time periods divided according to traffic flow changes in the historical traffic data are collected, the time periods with the small flow changes are divided together, and a traffic flow peak period and a smooth period are distinguished; 2) a pavement signal lamp phase is set; 3) traffic data of a pavement and a motorway is collected in real time, and a signal phase state and phase time are calculated; 4) whether a current green light phase demanding degree of the pavement and the motorway satisfies a signal lamp phase conversion condition is determined; 5) when the current green light phase demanding degree satisfies the signal lamp phase conversion condition, the signal lamp changes the phase. The invention provides the pavement signal lamp control method between the adjacent intersections based on the particle swarm algorithm. By using the method, intersection vehicles and traffic efficiency of pedestrians are considered, reliability is high and the traffic efficiency is increased.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to a traffic signal lamp control method. Background technique [0002] With the continuous increase of urban vehicles, the problem of pedestrians crossing the street is becoming more and more serious. When solving the problem of horizontal pedestrian crossing on urban arterial roads, in order to facilitate pedestrian crossing, it is necessary to set up sidewalks between two adjacent intersections to facilitate pedestrian crossing. Pedestrian crossing is contradictory to the traffic of arterial vehicles. In order to ensure the passage of pedestrian crossing and arterial vehicles, it is necessary to manage pedestrian crossing. [0003] There are three main management measures for pedestrian crossing: 1) timing signal control; 2) pedestrian button signal control; 3) no signal control. The sidewalk signal control method is generally to formulate a timing control plan based on the hi...
