Commuting by transfer in the public transit network is a green travel choice compared to private cars which should be encouraged when direct lines cannot take commuters their destinations. Therefore, commuting attitudes are important for finding appropriate ways attract more commuters. Firstly, since usually unobserved, combined revealed preference (RP) and stated (SP) survey was conducted Nanjing, China obtain observed attitudinal variables. Then market segmentation approach including...
