Travel time use and its impact on high-speed-railway passengers' travel satisfaction in the e-society

The availability of wireless networks and the pervasive use of mobile ICT devices have allowed passengers to conduct various e-activities during journeys. These various e-activities, in turn, may change people's conventional perception of travel time from being "wasteful" and "unproductive," to "desirable" and giving rise to satisfaction. Journeys on high-speed railway (HSR) is particularly relevant for transport researchers to probe into this question because of its characteristics of being medium to long-distance (typically taking half-an-hour or more), seat availability, and a smooth ride. Using a questionnaire survey on passengers along the Shanghai-Nanjing HSR route, this study aims to examine the nature of ICT device use and in-vehicle e-activities conducted by HSR passengers and the influence on their travel satisfaction with their on-board journey experience. Our results reveal a high percentage of ICT device use and a wide variety of e-activities such as e-working, e-communication, and e-reading for leisure on HSR trains. In addition, the higher use of ICT device was associated with an increase of passengers' travel satisfaction. Furthermore, we found a positive effect of work-related e-activities on travel satisfaction for business/work trips, while a positive effect of entertainment-related e-activities for non-business/work trips. Given that HSR is potentially a more sustainable transport mode, some possible policy implications are proposed to encourage people to use HSR, as opposed to driving or flying, for medium to long-distance intercity journeys.
