Sub-area multi-intersection group decision-making control method

Abstract

The invention discloses a sub-area multi-intersection group decision-making control method. The method comprises: based on a traffic flow continuity idea, bringing forward an adjacent intersection coordination rate, and giving a calculation formula of the adjacent intersection coordination rate and a sub-area multi-intersection total coordination rate; through research into a sub-area multi-intersection group intelligent coordination control strategy, designing a sub-area multi-intersection group decision-making control optimization architecture, and bringing forward an adjacent intersection decision-making control method and model; and by taking the size of the sub-area intersection total coordination rate as a signal timing basis, establishing a sub-area multi-intersection group decision-making control model, constructing a common signal period, a green ratio and a phase difference colony optimization function, designing a signal timing optimization process, and bringing forward an optimization algorithm based on genetic algorithms-simulated annealing such that sub-area multi-intersection group coordination control is realized. The method provided by the invention is applied to sub-area multi-intersection signal timing optimization under various traffic states of a medium-sized city, can improve the area coordination control capability, effectively reduces parking frequency and driving delay, and alleviates traffic congestion.

Description

technical field [0001] The invention relates to the field of regional traffic coordination control, in particular to a sub-area multi-intersection group decision-making control method. Background technique [0002] With the growth of road traffic volume and the enhancement of road network density in modern cities, the correlation between intersections is becoming more and more obvious. In a region or the entire city, the adjustment of traffic signals at an intersection often affects the operation of traffic flow at several adjacent intersections, and the congestion at an intersection may gradually spread to several surrounding intersections over time. and all intersections in the area. Therefore, the city's requirements for traffic signal control are becoming higher and higher, and the research on the theory and method of regional signal coordination control, which takes a certain region or even the whole city as the research object, has also attracted more and more attenti...

However, these regional coordinated control systems are only suitable for non-congested traffic conditions, which limits the actual operation effect of the regional coordinated control system to a certain extent.
