The role of access and egress in passenger overall satisfaction with high speed rail

Passenger satisfaction is critical to ridership growth of high speed rail (HSR). Each HSR trip includes at least four segments: access to HSR stations, waiting, line-haul, and egress from HSR stations. Satisfaction with any segment influences the HSR passenger experience. Previous studies often focus on passenger satisfaction with the line-haul segment, but overlook the effects of all four segments on overall HSR satisfaction, especially access and egress. Using a path analysis on the data collected from the Shanghai-Nanjing HSR corridor in 2016, this study explores the influence of access and egress segments on overall HSR satisfaction and the correlates of satisfaction with HSR access and egress segments. We find that HSR line-haul satisfaction dominates overall HSR satisfaction; HSR access and egress satisfaction together have an equivalent effect. Travel time and route familiarity are important to both access and egress satisfaction. Mode choice affects satisfaction with HSR egress, with egress by car carrying the largest utility of egress satisfaction, followed by rail transit, taxi, and then bus. Thus, to improve HSR experience, traveler information service and the integration of HSR with urban transportation system are critical.
