Paper, 2002Description: 9 sSubject(s): Bibl.nr: VTI 2002.0071Location: Abstract: This paper provides the first study on benefits of Snow and Ice Control for arterial roads in snowy regions in Japan to include influences on non-snowy regions. In Japan, Snow and Ice Control has been considered necessary social services for balanced development of the entire Japan, and the costs have been born by the national treasury. Nevertheless, benefits of the Services only for people in snowy regions have been measured in previous studies, because Snow and Ice Control are provided specific to snowy regions. Therefore, in this study, we validate the benefits of Snow and Ice Control to include how the Services impact on people all over Japan. This validation was carried out after confirming that people in non-snowy regions have a certain level of understanding about necessity of the Services, such as Snow removal and Improvement of Road Structure, through questionnaire surveys. In this paper, we estimate the benefits of the Services in the form of money value, as well as measure the level of understanding of people about Snow Removal, by analyzing results of our two questionnaire surveys. For evaluating wide range of the benefits, including direct and indirect ones, the Contingent Valuation Method (CVM)2 is used to estimate the benefits in the form of money value. The average WTP value for the Services is estimated at about JPY 4,000/year and household. The estimated benefits of the Services based on this WTP value are about JPY 170 billion to JPY 190 billion. This indicates that the benefits of the Service are sufficient enough compared to the actual annual costs of the Services, about JPY 120 billion. We also examine several factors that may cause the difference in respondents' attitudes. Main factors may include the following: where they live (they live in a snowy region or non-snowy region); and how well they know about life in snowy regions (they have relatives living in snowy regions, they have lived before in snowy regions, etc).Current library | Call number | Status | Date due | Barcode | |
