Abstract
This paper discusses the methodology for evaluating urban transportation system changes by means of the general spatial equilibrium approach within the framework of the Alonso-type city. It especially focuses on investigating whether or not Wheaton's assertion [1977] that only the information on trip demand is relevant to evaluate a transportation system change generally applies. For that purpose, two alternative models are analysed, each having its own hypothesis on an individual's behavior. By doing this, this paper demonstrates that Wheaton's statement does not necessarily apply in the evaluation of transportation system change other than a change in “fare”, and, on the contrary, any change in a transportation system can be exactly evaluated by the total change in land rent.
