Metro commuters' satisfaction in multi-type access and egress transferring groups

This paper considers both the access and egress stages as an entire process to analyze the satisfaction levels of commuters with metro commuter journeys. Based on a survey in Nanjing, China, seven intermodal travel groups are employed as targets for this analysis. The groups include Walk-Metro-Walk, Walk-Metro-Bus, Bike-Metro-Walk, Bike-Metro-Bus, Bus-Metro-Walk, Bus-Metro-Bus and Car-Metro-Walk, which are named according to the modes of transportation that are employed for access and egress trips. Binary logit models are developed for each group to identify the main factors of satisfaction level. The results show that access and egress stages serve important but different roles in the seven groups. Facility service qualities in two stages are the primary factors that affect overall satisfaction. The groups with same access or egress modes have significantly different core factors. Access by bike and bike-metro-transit users are concerned with bike parking safety, whereas bike-metro-walk users value parking spaces near metro stations. With two transfers between bus and metro, transit-metro-transit users indicate that the weak point in the access stage is the crowded spaces on buses. However, transit-metro-walk users value bus on-time performance, which is also valued by groups with metro-bus egress transfers. For egress by walking, commuters that use motorized modes for access are concerned with the egress walking environment, whereas users of non-motorized access modes are more concerned with egress walking spaces. The findings of this study are helpful for policy developments than can improve public satisfaction with commutes by urban metro.
