Abstract

The invention belongs to the field of an intelligent traffic control technology and relates to a transition method for an arterial road coordinate signal control scheme. The transition method is characterized by comprising the following steps: establishing conceptions of a leading phase chain, active phases and the like, taking green lamp transition time of the active phase as leading power for receiving the difference of technique parameter values of the current scheme and a new scheme; immediately starting transition process at the moment of issuing a scheme switching command; strictly limiting the variation amplitude of the green lamp transition time of the active phase, and leading the green lamp transition time of the active phase into solution procedure of transition process lasting time, transition signal period time and green lamp transition time; and respectively establishing nonlinear integer programming models for the transition signal period time and the green lamp transition time to the transition process experiencing a plurality of transition signal periods, the given transition process lasting time and the number of transition signal periods. The transition method has the characteristics of being fast and stable, and can be widely applied in a traffic signal control system.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic control, and relates to a transition method of an arterial road coordination signal control scheme. Background technique [0002] The coordinated signal control of urban arterial roads is to realize the linkage effect of traffic lights at adjacent intersections along the urban arterial road, so that some vehicles from the main direction of the upstream intersection can pass through several downstream intersections continuously at a certain speed. Phase difference, signal cycle time and green light time are the key technical parameters of the arterial coordinated signal control scheme. [0003] In order to adapt to the macroscopic time-varying characteristics of road users' traffic demand, traffic engineers are accustomed to dividing the control process of the whole day into multiple control periods. In each control period, the technical parameter values ​​of the control scheme are det...
