Abstract

This study explores the heterogeneous adoption preferences of physically disabled people for the introduction of wheelchair-accessible express bus in intercity travel. A face-to-face stated choice experiment for physically disabled people was conducted in South Korea, where significant policy efforts have been made to enhance adoption of wheelchair-accessible express bus. A latent class mixed logit incorporating panel effect was applied to explore inter- and intra-personal heterogeneity in the preferences. The results indicate that both inter- and intra-personal heterogeneity are statistically significant. The inter-personal heterogeneity was discontinuously separated into the classes by some socio-demographics, disability grade, and their intention to increase the number of intercity travel, affecting their value of travel time, then the continuously distributed personal heterogeneity is significantly observed in all the classes. The results further show that the adoption probability is higher in the group with a lower value of travel time. On average, the adoption probabilities are more sensitive to increased travel time or decreased travel cost of the wheelchair-accessible express bus.
