Abstract
This paper analyzed the willingness to pay (WTP) for reducing the lost time of railway users in Tokyo Metropolitan Area. A questionnaire survey was conducted to obtain the data for the analysis. Contingent valuation method (CVM) was applied to inquire their WTP in the survey. A statistical method for survival data analysis was applied to estimate the WTP function. As the results of the estimation, some significant factors which influence on the WTP were detected. Meanwhile, the expectation of the WTP was calculated using the estimated function. Then, it became clear that the expectation of the WTP was proportional to the amount of the lost time and that the expectation changed in accordance with the amount of the reducing of the lost time.
