Problems solved by technology

However, in the existing sub-area coordinated control, the signal control scheme of each intersection is fixed, and the applicability is poor. When the traffic flow in the road network changes, the traffic guidance effect of the control scheme of each intersection will be reduced.

Embodiment Construction

[0039] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein can be practiced in sequences other than those illustrated or described herein.

[0041] It should be noted that the cycle time refers to the time required for the signal to run a cycle when the signal light at the intersection changes, which is equal to the sum of the time of the green light, yellow light, and red light.

Abstract

The present invention provides a sub-area coordinated self-adaptive control method and device. The method includes: obtaining real-time traffic status data and signal timing data for coordinated control of each intersection in the calibrated sub-area; combining the signal timing data and the pre-established mixed integer Solve the linear programming model to obtain the position of the green wave zone; generate green wave guarantee constraints for each intersection according to the position of the green wave zone and signal timing data; generate single-point constraints for each intersection based on real-time traffic status data, and generate State data respectively determine the traffic status of each intersection, and generate the optimization target of each intersection according to the traffic status; optimize according to the green wave guarantee constraints, single-point constraint conditions and optimization objectives of each intersection, and determine the control of each intersection Program. The technical scheme of the invention can dynamically adjust the control scheme of each intersection according to the change of traffic volume while performing coordinated control on each intersection.

Description

technical field [0001] The present invention relates to the technical field of traffic signal control, in particular to a sub-area coordinated adaptive control method and device. Background technique [0002] With the rapid increase of car ownership, when controlling hundreds of intersections in the urban road network, the road network is often divided into multiple independent areas, each area contains one or adjacent Multiple intersections, the area is the sub-area in traffic control. [0003] Sub-area coordinated control refers to the linkage of traffic signals at each intersection in a sub-area for coordinated control, which can improve the efficiency of road network traffic and is an effective way to solve regional traffic congestion. However, in the existing sub-area coordinated control, the signal control scheme of each intersection is fixed, and the applicability is poor. When the traffic flow in the road network changes, the traffic guidance effect of the control s...
