Embodiment Construction

[0031] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0032] In order to realize the smooth transition of the coordinated control scheme, the transition adjustment method of the present invention includes the following steps:

[0033] a. The coordinated control area of ​​the traffic arterial line contains the numbered Ι 1 、Ι 2 、...Ι i ,...,Ι n The n intersections of , the common signal period when coordinating each intersection in the coordination control area is C A ;Choose the zero point as the reference point, and carry out the phase difference offset to each intersection in the coordination control area, S i for intersection I i At the scheme switching time T t The absolute number of seconds from zero, then at the scheme switching time T t , at the end of the period of the current control scheme, intersection I i The signal cycle of the corresponding target coordination scheme has been executed time C ...

Abstract

The invention relates to a method for controlling traffic signals, in particular to a transitional adjustment method for arterial traffic signal coordination control, and belongs to the technical field of arterial traffic signal coordination control. According to the technical scheme, the transitional adjustment method for the arterial traffic signal coordination control comprises the steps that the zero clock of the day is taken as the starting point of the coordination control scheme, and according to the remaining period time length, from the scheme switching time to beginning time of the next coordination period, of a road traffic signal machine, a period adjustment method in the coordination control transitional adjustment is given out; according to the period adjustment strategy in the coordination control transitional adjustment, distributing methods for time length of a green light in the period shortening and delaying processes are respectively given out, the time lengths of the green lights of all phases are obtained, and finally coordination control transitional schemes are formed. The method is convenient to operate, can achieve smooth transition of the coordination control scheme, and is wide in application range, safe and reliable.

Description

technical field [0001] The invention relates to a traffic signal control method, in particular to a transitional adjustment method for traffic arterial signal coordinated control, belonging to the technical field of traffic arterial coordinated control. Background technique [0002] In the coordinated control of urban traffic signal trunk lines, when the intersection signal is adjusted from the current coordinated control scheme to the target coordinated scheme, it is hoped that the control scheme can be adjusted quickly with the change of traffic conditions, but the change should not be too drastic, so as to To prevent sudden fluctuations in road traffic caused by sudden changes in timing parameters, resulting in blockage and impact on traffic flow, reduces the expected benefits of the implementation of the new scheme. Therefore, it is urgent to establish and realize a fast, stable and practical transition method of traffic signal coordination control scheme, so as to ensur...
