Abstract

The invention relates to the technical field of road traffic signal control, and specifically discloses a calculation method for pedestrian crossing induction signal timing in road sections, including the calculation of lost time for pedestrians starting, time for pedestrians entering a zebra crossing in a waiting area, time for pedestrians crossing the street, and extended time for subsequent arriving pedestrians Wait. The pedestrian crossing induction signal timing calculation method provided by the present invention comprehensively considers the waiting time of pedestrians crossing the street and the running conditions of upstream vehicles, triggers the pedestrian green light request signal; can dynamically respond and adjust the green light time of pedestrian crossing in real time, and satisfies the maximum extent Pedestrian crossing demands of different flow rates can improve the efficiency and reliability of pedestrian crossing on road sections, and ensure the efficient utilization of urban road traffic space-time resources.

Description

technical field [0001] The invention relates to the technical field of road traffic signal control, and more specifically, to a method for calculating timing of pedestrian crossing induction signals on a road section. Background technique [0002] At present, there are generally two types of pedestrian crossing signal control methods in urban road sections in my country: fixed scheme type and pedestrian button trigger type; fixed scheme type pedestrian crossing usually sets a fixed signal timing scheme, and successively releases pedestrians crossing the street and motor vehicle flow on the main road; The button-triggered type triggers the pedestrian phase through pedestrians who need to cross the street, so as to insert a fixed pedestrian signal timing, which solves the problem of waste of pedestrian green light signals when there are no pedestrians crossing the street; these two control methods are essentially preset and fixed The length of the pedestrian signal green light c...

[0002] At present, there are generally two types of pedestrian crossing signal control methods in urban road sections in my country: fixed scheme type and pedestrian button trigger type; fixed scheme type pedestrian crossing usually sets a fixed signal timing scheme, and successively releases pedestrians crossing the street and motor vehicle flow on the main road; The button-triggered type triggers the pedestrian phase through pedestrians who need to cross the street, so as to insert a fixed pedestrian signal timing, which solves the problem of waste of pedestrian green light signals when there are no pedestrians crossing the street; these two control methods are essentially preset and fixed The length of the pedestrian signal green light cannot meet the needs of different pedestrian crossing numbers for the length of the street crossing, and the pedestrian signal control cannot be combined with the traffic status of motor vehicles. The pedestrian crossing green light time under different scenarios, different traffic volumes, and different time periods cannot meet the needs of real-time dynamic optimization.

[0003] At present, pedestrian crossing signal control on road sections mostly only considers meeting the minimum pedestrian crossing time, or increases the pedestrian crossing time to meet the situation of a large number of pedestrian crossings. The relationship between this fixed pedestrian crossing time and the dynamic change of pedestrian crossing flow A stark contradiction is formed. The space-time resources of urban roads are not effectively utilized, and cannot meet the strong demand of traffic travelers for efficient and safe travel.
