Abstract

This paper aims to fill the research gap of the relationship between the access travel time (ATT) estimation and the accessibility to high speed railway (HSR) station. A regression analysis was developed on the basis of risk-return model to analyze the access travel time estimation error (ATTEE). The data sources were 1595 valid interview survey data at Beijing South Railway Station (BSRS), China in October 2016. The factors and scenarios included travel mode, departure time, and travel date, etc. The coefficients of ATT estimation were obtained by different travel modes. The results showed that the expected access travel time (EATT) has positive linear correlation with the actual access travel time (AATT). Accessibility was calculated by the ratio of AATT to EATT. The accessibility coefficients ranged from 0.89 to 1.38 in different travel modes, departure time, and travel dates. A smaller coefficient indicates better travel time reliability and accessibility. This study not only provides a useful tool to estimate the travel time budget required for access to HSR station, but also establishes a connection with the accessibility and ATTEE. It offers an opportunity to estimate ATT to HSR stations by different modes of transport, which can help to better understand how the accessibility of the feeder transport changes at different time periods.

Highlights

Due to the rapid development of high speed railway (HSR), the inter-city accessibility and capacity of railway networks have been improved [1,2,3,4,5]
The actual access travel time (AATT), which is the duration from their origin to HSR stations, become the key point for the access trip to HSR stations
The findings indicated that private car was the main travel mode for most people living in the suburb owing to faster speed and better accessibility

Summary

Introduction

Due to the rapid development of high speed railway (HSR), the inter-city accessibility and capacity of railway networks have been improved [1,2,3,4,5]. HSR can enhance the speed of long-distance inter-city trips with less travel cost and energy consumption [6,7,8,9]. A HSR station is the connection between inter-city transport and urban transport. The actual access travel time (AATT), which is the duration from their origin (home, hotel, etc.) to HSR stations, become the key point for the access trip to HSR stations. If ATT estimation error (ATTEE) is too large, it will lead to an insufferable waiting time at HSR stations. More seats and other service facilities will be needed in HSR stations
