Traffic signal light control method and system and traffic management system

Abstract

The invention discloses a traffic signal light control method. The traffic signal light control method comprises the following steps: receiving road condition information sent by a camera, processingthe road condition information to obtain a target instruction; and sending the target instruction to traffic signal lights, so that the traffic signal lights change according to the target instruction. Therefore, the traffic signal light control method provided by the embodiment of the invention has the advantages that the target instruction how the current traffic signal lights display can be dynamically given according to the received road condition information, display of the traffic signal lights can be flexibly adjusted, display time of green lights in a direction where traffic flow is low and pedestrians are few can be shortened, the condition that cars wait in one direction of a crossing while no vehicle passes in the other direction is avoided, and vehicle congestion condition on aroad is alleviated. The invention also provides a traffic signal light control system and a traffic management system, and the technical effects also can be realized.

Description

technical field [0001] The invention relates to the field of traffic management, more specifically, to a traffic signal light control method, system and traffic management system. Background technique [0002] As people's living conditions get better and better, and there are more and more private cars, urban traffic is often paralyzed. A large part of the reason is because of the signal lights. The time for vehicles to wait for the signal lights is too long, and there are so many vehicles waiting, which will cause serious congestion at this time.
