Determinants of Travel Choice Behaviour with Travel-Time Variability in the Presence of Real-Time Information

Abstract

This paper provided a statistical analysis of route and departure time choice behaviour under the effects of travel-time variability and real-time information for commuters in Japan using a web-based stated preference survey data. Furthermore, we developed a model predicting the relationship between the shift in average travel time and its reliability with the average travel time and real-time information provided. A factorial ANOVA underscored a significant effect of travel-time variability and real-time information on both departure time and route choice behaviour. The proposed model estimated the expected travel cost based on the estimated optimal departure time before and after having real-time information. This model may be useful for evaluating the benefit of travel-time reliability improved by the provision of real-time information.
