Problems solved by technology
Since the traffic flow is dynamically changing, the set maximum green may not be able to adapt to the needs of the traffic flow due to the sudden change of the traffic flow.
For example, during the peak period, there is a concentrated vehicle gathering at a certain intersection, and the traffic flow even exceeds the peak period. Therefore, the maximum green value set during the peak period cannot meet the traffic demand during this period.

The invention relates to the technical field of urban road traffic signal control, and specifically discloses a method for setting the maximum green at signal-controlled intersections, which includes: determining the initial maximum green, minimum maximum green, and maximum maximum green of each phase of the signal-control intersection ; Acquire the actual running green time of each phase of the signal control intersection; carry out self-learning dynamic optimization and adjustment to the initial maximum green of each phase according to the initial maximum green of each phase and the actual running green time of each phase, and obtain the time of each phase Adjusted new maximum green; repeat the steps of self-learning dynamic optimization and adjustment, and periodically iteratively update the adjusted new maximum green. The invention also discloses a signal control intersection maximum green setting system. The method for setting the maximum green of the signal-controlled intersection provided by the present invention can flexibly set the maximum green of the intersection to adapt to the sudden change of the green light time demand caused by the sudden change of the traffic flow.
Description
technical field [0001] The invention relates to the technical field of urban road traffic signal control, in particular to a method for setting maximum green at signal-controlled intersections and a system for setting maximum green at signal-controlled intersections. Background technique [0002] Inductive control is to install traffic flow detection equipment at the intersection, and according to the arrival of vehicles, the current green light release time is extended on the basis of the minimum green. Since the extension of the green light in the current phase will affect the traffic of vehicles in the intersecting direction, the waiting time will increase and the delay will increase. Therefore, the maximum green setting is one of the key parameters of induction control. If the setting is large and a maximum green is used throughout the day, the green light loss may be caused by inaccurate detection equipment; To adapt to the sudden change in the required green light tim...
