Urban rail transit receiving and transporting public transportation scheduled departing time generation method

Abstract

The invention discloses an urban rail transit receiving and transporting public transportation scheduled departing time generation method, which comprises the steps of acquiring scheduled arrival time of rail transit trains and the rated passenger carrying capacity of receiving and transporting public transportation vehicles according to a rail transit scheduled time table and receiving and transporting public transportation vehicle model configuration data provided by an operating enterprise; estimating the volume of rail transit transfer passengers based on historical passenger flow data, estimating the average transfer walking time of the passengers based on field research, and mastering an arrival pattern of non transfer passengers of surrounding block regions; setting virtual trains to act as carriers for the non transfer passengers, and sorting the virtual trains and actual trains according to the arrival time; building a receiving and transporting public transportation scheduled departing time generation model considering passenger carrying capacity constraints of the vehicles; and designing a genetic algorithm embedded with an enumeration process to acquire an optimal / an approximately optimal scheduled departing time scheme. The method disclosed by the invention is used for determining the urban rail transit receiving and transporting public transportation scheduled departing time which gives consideration to the passenger cost and the enterprise cost, reduces the waiting time of the passengers and reduces the operation cost of enterprises.

Description

[0001] Field [0002] The invention relates to a method for generating planned departure time of public transportation for urban rail transit, and belongs to the field of urban public transportation operation management. Background technique [0003] Urban rail transit transport buses refer to short-distance (or circular) ground bus lines specially designed for urban rail transit lines to pick up and drop off passengers, and are used to solve the "first and last kilometer" problem of rail transit passengers. The time for rail transit passengers to transfer to a pick-up bus includes two parts: transfer walking time and transfer waiting time. The transfer walking time has been basically determined in the planning stage of public transport facilities, while the transfer waiting time is determined by the degree of coordination between the rail transit timetable and the receiving bus timetable. In the absence of effective coordination, most passengers who transfer from rail transi...

AI Technical Summary

Problems solved by technology

[0004] Existing studies on the design of pick-up bus schedules seldom consider the constraints of bus passenger capacity. It is assumed that rail transit passengers can always take the first pick-up bus departing after their arrival. In the current period, a large number of rail transit passengers queue up to wait for multiple buses before they can take the pick-up bus and leave. It is contradictory to the reality; most of the existing research is devoted to the design of the departure timetable at equal intervals, and it is difficult to realize the effective timetable with the timetable of multiple rail transit lines at the same time. coordination; and few studies have considered non-transfer passenger needs when dealing with schedule coordination design
