Exploring the Effects of Congestion Pricing on Travel Behavior Responses Using Real-Time, Context-Aware, Stated-Preference Data

抄録

This study presents road users' preferences under congestion pricing as regards to alternative travel behavior responses in Hiroshima and Kumamoto, Japan. Utilizing real-time, context-aware, stated-preference survey data collected together with a two-week probe-person travel diary survey, we model the effects of congestion pricing on travel behavior responses, where explanatory variables include price, time saving, and egress distance to public transport. Using the developed model, we simulate behavioral changes to different congestion pricing schemes: cordon-based and distance-based. The results show that the distance-based scheme produced a higher level of spatial heterogeneity in the acceptance to pay the charge as compared to the cordon-based scheme, with relatively lower levels of probability for paying the charge at the center of the CBD for distance-based schemes. This indicates that distance-based schemes would be more preferable to reduce congestion in city central areas.
