Method and device for two-way green wave control

Abstract

The invention relates to the traffic control field, especially relates to a bidirectional green wave control method and a bidirectional green wave control device, which can be used to solve the problem of the conventional bidirectional green wave realizing scheme adopting the static green wave of inability of adapting well to the actual road traffic condition. The bidirectional green wave control method is characterized in that a target artery total green wave bandwidth acquisition rate can be determined according to the green signal ratio, the ideal green light starting time, and the phase difference of the intersection of various phase sequences of every intersection in the current adjusting period; whether the bidirectional green wave of the target artery can be determined; when the bidirectional green wave is realized, the traffic light of every intersection of the target artery can be set according to the green signal ratio, the phase sequence, and the phase difference of the intersection, which are corresponding to the total green wave bandwidth acquisition rate acquired during the realizing of the bidirectional green wave. By adopting the technical scheme provided by the invention, the parameter information of every intersection can be updated periodically, and therefore the traffic lights of the target artery can be set dynamically according to the parameter information corresponding to the total green wave bandwidth acquisition rate acquired during the realizing of the bidirectional green wave, and then the better adaptability to the actual road traffic condition can be provided.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a method and device for bidirectional green wave control. Background technique [0002] Urban transportation plays an important role in economic and social development, especially the transportation in the central area of ​​the city. The improvement of its operation efficiency can bring huge economic and social benefits. The contradiction between traffic demand and road facilities cannot be well resolved by merely increasing road construction, especially in the urban central area, where the road network density is already quite high, and it is impossible to carry out large-scale road construction to increase the capacity of the road network . Scientific traffic management and control is an important measure to give full play to the traffic capacity of the road network and an effective way to solve urban traffic problems. Reasonable traffic signal control can effectively allocate ...
