This research project aims to develop evaluation methods of transportation project based on subjective valuesIn 2002, this project aims to monetarily evaluate customers' subjective values including satisfaction with Low-Floor Light Rail Vehicle (LRV) by applying Contingent Valuation Method (CVM). Original surveys were conducted in Hiroshima targeted on tram users and residents along the tram route, A new method correcting the biases inherent in willingness-to-pay responses is proposed. As a result, it is found that the customer satisfaction for getting on and off the LRT would be improved by the introduction of the LRV. Moreover, a new method proposed in this study has capability to correct biases caused by survey design and to indicate the interval of the true subjective valuesIn 2003, this project attempts to explore the sources of respondents' uncertainty regarding their willingness to pay (WTP) in CVM (Contingent Valuation Method). To capture the uncertainty in respondents' responses, the concept of certainty level for dichotomous choice response is introduced in CVM survey proposed in the previous year. Furthermore, an alternative approach based on fuzzy logic (i.e, fuzzy-CVM approach) is newly developed to incorporate the uncertainty into the WTP estimates. The approach can tackle the irreversible effects of WTP and WNTP (willingness not to pay). Moreover this paper addresses how to estimate the upper and lower values of WTP. Throughout an empirical analysis in Japan, it is shown that the respondents' WNTP is more sensitive to both bid amount and confidence level than the WTP. It is concluded that the Fuzzy-CVM can improve the reliability of the conventional CVM

该研究项目旨在根据2002年的主观价值开发运输项目的评估方法，该项目旨在通过应用随意估值方法（CVM）来评估客户的主观价值，包括对低地板轻轨车辆（LRV）的满意度。原始调查是在针对电车用户和电车路线居民的广岛的广岛进行的，提出了一种新的方法，以纠正意愿付费响应固有的偏见。结果，发现通过引入LRV，可以提高开发和关闭LRT的客户满意度。此外，这项研究中提出的一种新方法具有纠正由调查设计引起的偏见，并指出了2003年真正的主观价值的间隔，该项目试图探索受访者对CVM中受访者对付款意愿（WTP）的不确定性的来源（或有估值方法）。为了捕获受访者反应的不确定性，在上一年提出的CVM调查中引入了确定性水平的确定性水平概念。此外，新开发了一种基于模糊逻辑（即模糊CVM方法）的替代方法，以将不确定性纳入WTP估计值中。该方法可以解决WTP和WNTP的不可逆转效果（愿意不付款）。此外，本文介绍了如何估计WTP的上和下值。在日本的经验分析中，这表明受访者的WNTP比WTP更敏感出价和置信度。结论是，模糊CVM可以提高常规CVM的可靠性
