The Influence of Environmental Deterioration and Network Improvement on Transport Modal Choice

Transport modal choice is considered to be influenced by natural environmental change and transport network improvement. This paper reveals how these impacts affect individualsf decisions on selecting transport mode under an extension plan of Osaka Monorail Loop-line. To estimate these impacts, a Stated Choice (SC) experiment is carried out for collecting the neighborhood data around the monorailfs extended area. Our model is estimated by the Heteroscedastic Extreme Value (HEV) specification in order to avoid Independence from Irrelevant Alternatives (IIA) assumption in the Multinomial Logit (MNL) model. Both the results of full-sample and sub-sample data imply that residents prefer public transport modes (monorail or bus) to private car when either natural environment becomes worse or transport network is improved.
