Traffic signal control method and traffic signal control system for mobile communication terminal

Abstract

The invention belongs to the technical field of transportation, and discloses a traffic signal control method and a traffic signal control system of a mobile communication terminal, which collect state image data of traffic signal lights through an image acquisition module; and send different state signal instructions of traffic signal lights through an instruction sending module; The central control module dispatches the traffic signal light image processing module to process the status image of the traffic signal light collected by the image acquisition module; assigns a time period to the traffic signal through the signal timing module; detects the fault signal of the traffic signal light through the fault detection module; displays the collected traffic signal through the display module Status image of a semaphore. The invention models a single intersection through the linear programming of the signal timing module, so that the intersection can reach the maximum traffic flow that can pass through, so that the traffic control technology has good flexibility, adapts to rapid changes in traffic flow, and has low cost, and finally achieves full use of the road the goal of.

Description

technical field [0001] The invention belongs to the technical field of traffic, and in particular relates to a traffic signal control method and a traffic signal control system of a mobile communication terminal. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Where traffic separation cannot be achieved at road intersections, a traffic direction measure used to assign rights of way to traffic flow in time. The role of traffic signals is to scientifically allocate the right of way of vehicles and pedestrians on the road, so that they can pass in an orderly and smooth manner. The setting of traffic signal lamps, traffic signs and traffic markings shall comply with national standards. Traffic signals can make vehicles drive in an orderly manner, reduce congestion, reduce the occurrence of traffic accidents, enable all traffic participants to drive in an orderly manner, and avoid the waste of time caus...

Problems solved by technology

[0005] When collecting illegal images of vehicles at traffic intersections, due to the dark light in some scenes, in order to clearly identify vehicle information, it is often necessary to increase the exposure time of the camera, resulting in oversaturation in the traffic signal area, red lights appear yellowish or Whitening phenomenon, green and yellow lights appear whitening, and the shape of traffic lights becomes blurred;

[0006] At the same time, the existing traffic control technology is mainly timing control and induction control; the timing control has the disadvantage of poor flexibility and is not suitable for rapid changes in traffic flow; induction control is mainly realized by hardware, and the cost is high

[0007] The traditional color image contour extraction method is susceptible to the interference of initial contour points and slow convergence speed when extracting the target boundary, which leads to the noise of the extracted color image contour, which affects the effect of image segmentation
