Automatic induction control method of crossing signals for pedestrians and non-motor vehicles at intersection

Abstract

The invention discloses an automatic induction control method of crossing signals for pedestrians and non-motor vehicles at intersection. The method is based on signal group optimization control logic, breaks through the way that pedestrians and non-motor vehicles follow the signal phase of motor vehicles to pass, takes the pedestrian or non-motor vehicle signal group as an independent control unit, adopts automatic induction detection of pedestrians and non-motor vehicles, a secondary street crossing mode and the optimized control logic algorithm based on a signal group, and provides for pedestrians or non-motor vehicles the green light passing right for many times by adopting a 'crack pin' mode on the premise of not generating green light conflict with the motor vehicle signal group. Theautomatic induction control method of crossing signals for pedestrians and non-motor vehicles at intersection has the advantages that the waiting time for red light is reduced, the traditional fixedphase control limit of following the motor vehicle signal group to pass is broken through, and the method is more suitable for the ubiquitous application scene with large pedestrian and non-motor vehicle street crossing requirements and strong randomness, wherein pedestrians and non-motor vehicles can be ensured to cross the street safely while the traffic efficiency of the motor vehicles can be effectively considered, and the overall traffic control efficiency of the intersection is effectively improved.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to an automatic sensing control method for pedestrians and non-motor vehicles crossing the street at an intersection based on the optimal control logic of signal lamp groups. Background technique [0002] Most urban road intersections in my country have a large demand for pedestrians and non-motorized vehicles to cross the street, especially at large intersections. The traffic organization and signal control scheme for pedestrians and non-motorized vehicles crossing the street is still a difficult problem in practical application. The traditional signal control method for pedestrians and non-motor vehicles to cross the street is to follow the signal phase of motor vehicles, that is, the signal lights of pedestrians and non-motor vehicles and the signal lights of non-conflicting motor vehicles are combined into one signal phase, and the green light time is obtained sync...
