Embodiment Construction

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0061] In order to realize the reasonable allocation of traffic resources, the embodiments of the present invention provide a traffic light control method and system.

[0062] Such as figure 1 As shown, the embodiment of the present invention is applied to traffic lights at intersections. The intersections are divided into arterial roads 100 and non-arterial roads 200. The traffic lights controlling the traffic of arterial roads 100 are the first traffic light...

Abstract

The embodiment of the invention provides a traffic light control method and system. The traffic light control method comprises the following steps: according to a first quantity of vehicles waiting on a main trunk traffic road, determining preset duration corresponding to a main trunk traffic road vehicle threshold range as a first green light duration, comparing target quantity of vehicles which do not pass on the main trunk traffic road with a target quantity threshold, and determining a second green light duration on a non-main trunk traffic road; when the target quantity is higher than the target quantity threshold, determining that the second green light duration is the preset duration; and when the target quantity is not higher than the target quantity threshold, determining preset duration corresponding to a non-main trunk traffic road vehicle threshold range as the second green light duration according to the second quantity of the vehicles waiting on the non-main trunk traffic road. By virtue of the technical scheme provided by the embodiment of the invention, traffic resource is reasonably distributed under the premise of guaranteeing priority pass of the main trunk traffic road.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a traffic light control method and system. Background technique [0002] Since the appearance of transportation tools, traffic control has also emerged as the times require. Especially in modern times, in order to ensure efficient and safe traffic order, a series of traffic rules have been produced, and traffic lights are one of them. Traditional traffic lights are controlled by a "fixed pairing" method, that is, the red light and the green light respectively display a set fixed duration. However, with the rapid growth of urban vehicle ownership, especially when the traffic flow at intersections varies greatly at different times, the traditional traffic light control system cannot relieve traffic pressure, but will lead to more serious congestion. [0003] In order to solve the problem that the traditional traffic light control system cannot adapt to the uncertainty of t...
