Signal regulating method for pedestrian crossing road section of bus prior passage

Abstract

The invention discloses a signal regulating method for a pedestrian crossing road section of bus prior passage. The signal regulating method for the pedestrian crossing road section of bus prior passage comprises the steps of step10, collecting traffic information of pedestrian crossings, step20, starting pedestrian crossing control, recording a moment when an accumulative number, collected by dynamic real-time data in the step10, of the pedestrian crossings changes from 0 to 1, carrying out step30, and staying in the step20 until signal regulation is finished when an accumulative number, collected by the dynamic real-time data in the step10, of the pedestrian crossings does not change from 0 to 1, step30, determining a starting moment of a pedestrian crossing green light, step40, determining the required number of the pedestrian crossings, step50, determining an end moment of the pedestrian crossing green light, and step60, carrying out signal switching, switching pedestrian crossing signals after the end moment of the pedestrian crossing green light, switching a pedestrian crossing signal into a red light signal, and returning to the step20. The signal regulating method for the pedestrian crossing road section of bus prior passage combines pedestrian crossing green light signals and bus real-time operation in the process of bus operation, and improves the operation efficiency of a public traffic system and the traveling efficiency of passengers.

Description

technical field [0001] The invention relates to urban pedestrian crossing signal control technology and bus priority passing technology, in particular, relates to a signal regulation method for pedestrian crossing section for bus vehicles to pass preferentially. Background technique [0002] At present, our country is in a critical period of rapid development of social economy and urbanization process. The continuous expansion of the city scale and the continuous growth of the population have led to the continuous adjustment and optimization of the city's industrial structure and spatial pattern, and the city's various functions are becoming more and more perfect. . On the one hand, the rapid development of cities will inevitably bring about an increase in the travel distance and demand of urban residents, which provides a good opportunity for the development and construction of urban transportation systems; The contradiction between limited capacity has induced a series of...

Problems solved by technology

[0003] However, in actual operation, the efficiency of public transport is often disturbed by other factors

Especially on long sections with pedestrian crossings, the demand for pedestrian crossings is not well coordinated with the faster-moving buses, and the crossing signals are not included in the bus signal priority control system. Vulnerable to pedestrian crossing signals

Generally speaking, public transport vehicles can only reduce the speed or even stop to wait for the pedestrian crossing green light signal to end, which greatly reduces the operating efficiency of public transport vehicles and affects the smooth operation of the urban traffic system

Moreover, when pedestrians are crossing the street at peak hours, frequent pedestrian crossing signals will affect the reliability and stability of bus operation, and this impact will soon spread to the entire bus system, resulting in the negative effects of unhappy buses and low efficiency

At present, the implementation and guarantee technology of bus priority rarely involves pedestrian crossing, and the actual connection and linkage design between the two are seldom involved.
