Subway departure time optimizing method for reducing transfer time of tunnel transfer stations

Abstract

The invention discloses a subway departure time optimizing method for reducing transfer time of tunnel transfer stations. The subway departure time optimizing method includes steps of acquiring train numbers and arrival time intervals of all lines within a set study time range; computing the sum of transfer walking time of passengers of two platforms; judging whether to optimize departure time according to the ratio of average arrival time interval of the two lines and the sum of the transfer walking time of the two platforms; optimizing departure train numbers and the time arriving a station S of the first line to the fourth line within the study time range; and aiming to optimize train numbers of previous and later lines to be identical, adjusting the obtained departure train numbers and the obtained time arriving the station S of the first line to the fourth line. The subway departure time optimizing method for reducing transfer time of tunnel transfer stations can guarantee that passengers walk to a transfer platform as soon as a train to be transfer arrives and keep the original train number without change, thus, transfer time of passengers can be shortened, attraction of subway is improved, the problem of traffic jam caused by private cars is alleviated, and operating cost of subway operation enterprises cannot be additionally added.

Description

Technical field [0001] The invention relates to the technical field of subway operation management, and in particular to a method for optimizing the departure time of a subway that reduces the transfer time of a passageway transfer station. Background technique [0002] At present, my country is in a critical period of rapid development of social economy and urbanization. The scale of cities continues to expand, and the number of private cars is increasing rapidly. With this comes the increasingly serious problem of urban traffic congestion. Vigorously developing public transportation has become an important way to alleviate problems such as urban congestion and traffic pollution. The subway has been widely recognized for its high punctuality, large transportation volume, comfort, energy saving and environmental protection, and has been favored by more and more cities. . [0003] The subway line network can form the backbone network of urban public transportation, but it cannot ov...

AI Technical Summary

Problems solved by technology

In non-peak hours, the departure interval of subway trains is longer, and the waiting time for passengers to transfer is longer.

[0004] In view of the situation of subway transfers during off-peak hours, the operating company did not coordinate and optimize the departure time of the trains on the two lines according to the walking time of the transfer passengers and the departure interval of the two lines. It still uses the traditional method to arrange the departure time according to the passenger flow. , which greatly increases the waiting time of transfer passengers, adversely affects the convenience and comfort of travel, weakens the attractiveness of the subway, and becomes an important restrictive factor for the development of urban public transportation
