Abstract

The invention relates to a traffic flow capture-based traffic signal lamp and a speed limit sign intelligent adjustment method, and belongs to the technical field of traffic signal control. The invention provides a traffic flow capture-based traffic signal lamp and a speed limit sign intelligent adjustment method, wherein a traffic signal lamp and an electronic speed limit sign can be dynamicallyadjusted in real time and the traffic jam can be effectively avoided. According to the technical scheme of the invention, the traffic signal lamp comprises a collection camera for collecting the traffic information of road vehicles, a control computer provided with the traffic simulation software, and a cloud database server used for storing traffic signal lamp and electronic speed limit sign adjustment schemes. The collection camera is used for collecting the real-time road traffic information, and then synthesizing the information to a control computer to carry out simulation operation afterprocessing the information. After that, the dynamic adjustment of the traffic signal lamp and the electronic speed limit sign can be realized through matching the real-time road traffic condition with an optimal traffic signal lamp and electronic speed limit sign adjustment scheme.

Description

technical field [0001] The invention relates to an intelligent adjustment method for traffic signal lights and speed limit signs based on traffic flow capture, and belongs to the technical field of traffic signal control. Background technique [0002] At present, intelligent traffic light signal control technology has been proposed by more and more people as an important technology in the field of intelligent transportation and applied to new road traffic management models. Different from the traditional fixed-period traffic light control mode, the new signal light control mode can dynamically adjust the time interval of traffic lights according to the actual road conditions, so as to avoid vehicles in one direction of the intersection waiting for the red light and being too congested while other directions But idle green light time and so on. [0003] Most of the existing intelligent traffic light signal control technologies use equipment such as ground pressure sensors an...
