Abstract
Travel route options for passengers can provide data support for railway line planning, passenger flow organisation, and train operation establishment. A critical review of the literature indicates that previous studies mainly focused on choices offered by a single railway network path without much consideration of China’s normal-speed and high-speed integrated railway network and the effect of train timetable on passengers’ travel choice. In this study, a method based on generalised cost is proposed to discover the valid routes of passenger travel in the integrated network of China’s normal-speed and high-speed railways. After quantifying the effects of train fare, travel time, transfer, travel convenience, comfort, and other factors on the generalised expenses of passengers, this study presents a generalised cost determination method when individuals select an option from different seats of different trains of specific railway transport products. Theoretically, the valid routes considering the train schedule is defined, and a valid route search algorithm is designed using the deep traversal idea in a new valid route searching network. Considering the Lanzhou-Beijing passenger travel routes as an example, this study verifies the practicability of the generalised cost calculation method, as well as that of the valid routes search method.
Highlights
High-speed railway, as a land transportation mode with high speed, large capacity, low energy consumption, and environmental protection, is setting o a wave of development all over the world
As the country with the longest operating mileage of normal-speed and high-speed railways worldwide, China’s normal-speed railway and high-speed railway operation mileages reached 132,000 and 30,000 kilometres, respectively, by the end of 2018 [1]. erefore, railway networks formed by high-speed and normal-speed railways have begun to expand
Ways of making the passenger decision-making service more demand-responsive have stood under the spotlight. erefore, as a base of the railway passenger decision-making service, it is essential to study the railway passenger path choice
Summary
High-speed railway, as a land transportation mode with high speed, large capacity, low energy consumption, and environmental protection, is setting o a wave of development all over the world. By analysing the main factors that affect the route choice behaviour of passengers, Yang et al [8] established an optimisation model for optimising the route selection for railway passengers by minimising the total travel time, total price cost, transfer time, transfer distance, and fatigue recovery time. Is study integrates the high-speed and normal-speed railway networks and presents a detailed study of all the components (including fare, time, convenience, and comfort) of the generalised cost of efficient travel routes. E significant contributions of this study are as follows: (1) the calculation method of the generalised cost is proposed, including the calculation methods of comfort cost, convenience cost, and transfer cost, and (2) A method of passenger travel routes search between the Origin-Destination (OD) considering the train schedule under the dualnetwork integration is proposed.
