The Attitude of Bus Users to Travel Time Variability
This paper tackles the fact that past research has not yet overcome the issue of whether the effects of unpredictable travel time variability (TTV) on the behavior of travelers are fully explained by their trip scheduling considerations. There is evidence that this is the case for car users and it has been shown that the choices of railway users are also influenced by the inconvenience caused by TTV. However, for bus users there is hardly any evidence at all. In this paper, factors affecting trip scheduling and attitudes to TTV among bus users are investigated, based on a survey taken in the city of York, England. The survey methodology and its design as an internet-based questionnaire are described. The results confirm that the influence of TTV is best explained indirectly through scheduling considerations. But since the common treatment of TTV in practice is through mean-variance formulations, the author examines how using the simple approach rather than the correct one affects the economic interpretation of TTV and this analysis reveals a massive bias. In addition, the paper presents main conclusions from an attempt to extend the scheduling model into a Mixed Logit formulation, accounting for taste variations within the studied population. Comparing the distribution of the willingness to pay from the Mixed Logit model to an estimate based on sub-sampling illustrates difficulties in using the Mixed Logit model for willingness to pay analysis.
