Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Referring to FIG. 1 , it illustrates a flowchart of an embodiment of a coordinated inductive traffic control method of the present invention. As shown in the figure, the following steps are included:

[0037] S100, the green light of the i-th phase starts. In this specific embodiment, the ith phase represents the current phase, the i+1th phase represents the next phase of the current phase, the i+2th phase represents the next phase of the i+1th phase, and the i-1th phase represents the current phase The previous phase of the phase; this step indicates that the green light of the current phase is on;

[0038] S101, judging whether the i-th phase is a coordinated phase, if so, execute step S114, otherwise execute step S102;

[0039] S102, judging whether the next phase of the i-th phase (i.e. the i+1th phase) is a coordinated phase, if so, execute step S115, ...

Abstract

The invention discloses a coordinated inductive control method for traffic, comprising steps as follows: a, obtaining stopping green light time at present phase position, b, judging whether the present phase position receives running requests before finishing the first green light time, if the present phase position receiving, then, carrying out the step c, c, judging whether the green light time in the present phase position is longer than the stopping green light time, and if the green light time in the present phase position being longer, then, finishing the green light in the present phase position, if not, prolonging the green light time in the present phase position. The invention judges whether the present phase position receives the running requests in the stopping green light time, if the present phase position receives the running requests in the stopping green light time, then, prolonging the green light time of the present phase position, thereby enabling the green light time to satisfy the actual demands better.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a coordinated inductive traffic control method. Background technique [0002] At present, urban traffic problems are becoming more and more serious, and there is an urgent need to manage them through effective means, among which traffic control is one of the effective means. [0003] In the urban road network, intersections are very close to each other. When single-point signal control is set at each intersection, vehicles often stop and drive when encountering red lights, resulting in poor traffic and aggravating environmental pollution. In order to reduce the parking time of vehicles at various intersections, especially to enable vehicles on arterial roads to run smoothly, people first study the connection of a group of adjacent traffic signals on an arterial road, and coordinate control, and arterial intersections appear. Coordinated control system of traffic signals (referred ...
