Abstract

The invention relates to a green wave induction control method and a system of traffic flow through intelligent cluster signal lamps, belonging to the technical field of intelligent traffic. The method comprises the steps of: setting intelligent signal lamps along a road and at intersections for sensing vehicle movement and wireless transmission and processing vehicle information, clustering single signal lamps to proper clusters to form lamp clusters by utilizing an intelligent cluster preprogram through information communication, performing communication and negotiation among the lamp clusters to form flowing green wave bands or green wave band lamp clusters so as to realize cluster flow and green wave flow traffic induction of the intelligent signal lamps. The system comprises intelligent signal lamps and red and green signal lamps arranged along the road and at intersections, an information communication transfer station and a central monitoring station, wherein an intelligent chips, a vibration sensor, a wireless data transmitter, a power supply and a three-color LED (light emitting diode) lamp are built in each intelligent signal lamp, the intelligent signal lamps are in wireless connection, and the intelligent signal lamps and the information communication transfer station are in wireless connection, and the central monitoring station is connected with the information communication transfer station through a network. The method and the system, disclosed by the invention, have the advantages of reliable system and good traffic flow control effect, etc.

Description

technical field [0001] The invention relates to a method and system for controlling traffic flow induced by green waves of cluster intelligent signal lamps, and belongs to the technical field of intelligent traffic control. Background technique [0002] With the increase of urban road traffic load, the phenomenon of vehicle congestion is becoming more and more prominent. Using traffic control technology to induce and clear road vehicles is a blessed way to solve urban traffic problems. At present, intelligent traffic control technology mainly includes adaptive path induction method based on bee colony algorithm, dynamic fuzzy control and neural network intelligent traffic signal control technology, traffic light control technology based on wireless sensor network, etc. [0003] The adaptive route induction method based on the bee colony algorithm is to apply the bee colony algorithm to intelligent transportation, and realize the dynamic induction of vehicle routes through th...
