摘要：In this talk, I will first briefly introduce building blocks associated with Economics of Urban Transportation, and then report two of my group’s recent research. One of them is to investigate the effects of social interaction information from friends on commuters’ daily route choice decisions (at the micro level).We develop a day-to-day route-choice learning model with friends’ travel information based on the Cumulative Prospect Theory (CPT), and conduct a laboratory behavioral experiment to validate the model. Experimental results show that a larger rate of social interactions in an online travel community does not necessarily lead to a better route-choice outcome for individuals or the whole system. Furthermore, the overall impact of the amount and percentage of friends choosing each route on the generation of perceived travel time may be negative or positive, depending on the number of members in an online travel community. The other is to provide new insights into commuters’ mode choice behavior in a monocentric closed city with endogenous population distribution (at the macro level), where a congested highway and a crowded railway provide commuting services for residents on a linear urban corridor. We explore typical equilibrium mode-choice patterns with exogenous city boundary and population distribution, and incorporate residents’ mode choice into an urban spatial equilibrium model. Using comparative static analysis, we find that the urban corridor expands with the increase of railway fare if both of highway congestion and transit crowding are ignored, but it is uncertain if not. We also discuss the changes of the urban form, utility level of residents and social welfare with different railway fare and subsidy policies. The numerical results show that the distance-based fare policy with low subsidy should be preferred because it can realize the Pareto-improved social welfare and utility level of residents.
