摘要

Travel time saving has been thought of as the major benefit of transport investment in cost-benefit analysis in many developing cities. However, it has been criticized that transport project evaluation based on travel time savings can lead to inequitable results. In particular, a positive association between individual capability and travel time expenditure indicates that travel time savings might be beneficial mainly for those who are more capable. In this study, we empirically examine the association between individual capability and travel time expenditure in 17 developing cities by using person-trip survey data collected by Japan International Cooperation Agency (JICA). We explore the mechanism how the capability affects travel time expenditure with a particular focus on mediation and moderation effects of residential location choice on travel time. Mediation and moderation effects are modeled by using the person-trip survey data collected in Hanoi (Vietnam) in 2004. The results indicate that residential location choice influences the association between individual capability and travel time expenditure significantly.
