TRAFFIC LIGHT CONTROL SYSTEM FOR A HIGH FLOW INTERSECTION
First Claim
1. A traffic light control system for a high flow intersection, comprising a CCU for controlling traffic lights and a plurality of surveillance cameras for monitoring traffic conditions in the intersection and on lanes going out of the intersection, wherein the surveillance cameras capture traffic flow images in the intersection and on the outgoing lanes, which are converted by an interface circuit and sent to the CCU for processing, wherein the CCU processes the images and determines whether an outgoing lane is congested according to the processed images, switches and keeps on red lights for corresponding incoming directions when the outgoing lane is determined to be congested, and resumes a previous lighting mode after congestion is dissipated.

Abstract
The present invention relates to a traffic light control system for a high flow intersection comprising a CCU (Central Control Unit) and a plurality of surveillance cameras for monitoring the traffic condition in the intersection and on the lanes going out of the intersection, wherein the surveillance cameras capture traffic flow images in the intersection and on the outgoing lanes, which are converted by an interface circuit and sent to the CCU for processing, wherein the CCU determines whether an outgoing lane is in congestion according to the processed images, switches and keeps on red lights for corresponding directions when the outgoing lane is determined to be in congestion, and resumes the former lighting mode after the congestion is dissipated. Such a control system may, when an outgoing lane is determined to be in congestion, automatically switches and keeps on red lights of corresponding incoming lanes to prevent waiting vehicles from pulling in the intersection, thereby allowing the congestion to be dissipated.
