Time-varying-passenger-flow-driving type passenger flow matching and schedule adjustment method of urban mass transit

Abstract

The invention discloses a time-varying-passenger-flow-driving type passenger flow matching and schedule adjustment method of the urban mass transit. Operation passenger flow data of an automatic faircollection (AFC) system are collected and arranged; the operation passenger flow data are distributed to a rail traffic network to obtain minute-based time-varying passenger flow OD data of all linesin the network as the input; the time-varying passenger flow OD data match an existing train working diagram; a matching state is determined and a congestion interval and an idle interval are analyzed; and compiling parameters of the operation diagram are modified and the train working diagram is updated. According to the invention, a coupled matching relationship between the time-varying passenger flow demand and the train supply is demonstrated essentially; an operation management problem of the urban mass transit in a super-crowding state is solved; and the waiting time of passengers at stops is shortened. With the programmed system, a decision-making plan is provided for the urban mass transit operation company for daily operation management, so that the operation service quality and the management level are improved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, and specifically relates to a time-varying passenger flow-driven urban rail transit passenger flow matching and timetable adjustment method. Background technique [0002] With the improvement of my country's economic level, the process of urbanization and motorization is also accelerating. Urban rail transit has become an important measure to alleviate urban traffic congestion due to its large capacity, fast operation speed, small footprint, energy saving and environmental protection. . The operation of trains in rail transit is based on timetables, which play an important role in the organization and adjustment of urban rail transit systems. [0003] Time-varying passenger flow is the unbalanced and time-dependent passenger flow arrival in a period of time due to the randomness of passenger flow arrival. Balanced passenger flow is within a certain period of time, assuming that the ar...
