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 ...

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. According to the technical solution provided by the present invention, the transitional adjustment method for the coordinated control of traffic arterial signals includes: taking zero o'clock of the current day as the starting point of the coordinated control scheme, according to the remaining period of the road traffic signal from the next coordination period when the scheme is switched According to the cycle adjustment strategy in the transition adjustment of coordinated control, the distribution method of the green light duration when the cycle is shortened and extended is given respectively, and the green light duration of each phase is obtained. Finally, each phase is formed. Coordinate and control transition programs. The invention is easy to operate, can realize the smooth transition of the coordinated control scheme, has wide adaptability, and is 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...
