Embodiment Construction

[0035] The specific implementation of the present invention will be further introduced below in conjunction with the accompanying drawings.

[0036] The method for dynamically dividing the traffic control sub-area in this embodiment includes the following steps:

[0037] 1. Relevant data collection for correlation analysis

[0038] Use the distance measurement tool to collect the distance between adjacent intersections, and the distance between adjacent intersections will be used as a static factor affecting the correlation between intersections; collect the associated traffic volume between adjacent intersections and predict the maximum associated traffic flow in the next period Vehicle increment, the sum of the associated traffic volume between adjacent intersections and the maximum associated traffic volume as the maximum traffic volume between adjacent intersections, the maximum traffic volume between adjacent intersections will be used as the influence intersection The d...

Abstract

The invention discloses a method capable of dynamically partitioning traffic control subregion, including the following steps: acquisition of relevant data for associativity analysis; determining degree of association of adjacent crossings by utilizing the acquired data; further determining combination degree of association of multiple crossings; traversing all possible control subregion partition schemes by adopting subregion partition layer diffusion algorithm and selecting the control subregion partition scheme with maximum performance index by comparation; and partitioning a new traffic control subregion according to the maximum performance index scheme obtained in real time. The invention provides the definition of the degree of association of adjacent crossings and analysis algorithm thereof and realizes effective combination of association key elements of the adjacent crossings; and the provided coordination control subregion partitioning method based on analysis of the degree of association considers various factors influencing the control subregion partition and realizes mensuration, standardization and systematization of the control subregion partition.

Description

technical field [0001] The invention relates to regional traffic coordination control, in particular to a method for dynamically dividing traffic control sub-areas. Background technique [0002] When implementing coordinated control of traffic signals in a large area, it is often necessary to divide it into several relatively independent parts, and each part implements a corresponding control plan according to its own traffic characteristics. These relatively independent parts are called control sub-areas . Reasonable division of control sub-areas will facilitate the implementation of flexible control strategies, so that blocks with widely different traffic characteristics can obtain the best control effect, which is the premise of realizing effective coordinated control of traffic areas. Establishing a set of comprehensive and effective control sub-area division indicators to realize the quantification, standardization and systematization of control sub-area division has b...
