Measurement of Human Cost Of Trajfic Accidents Using CV And SG Survey Methods

Abstract

This paper is aims to propose the introduction of statistical value of life concept using willing-to-pay method for estimation of human cost in monetary terms due to traffic accidents. In order to estimate of the value, questionnaire survey is designed according to the previous study of UK. which uses CV method and SG method. Human cost of fatal accidents is estimated 266 million yen, which is 8 time as official value in Japan. Ratios of non-fatal human cost appeared to be relatively high compared with official values in Japan as well. The authors found that variances of observed values from survey could not be ignored, and effects by attributes of subjects could not be cleared.
