Abstract

In order to improve the accuracy and reliability of VOSL assessment in road traffic safety, an evaluation model on VOSL was established based on the quadruple-bound dichotomous CVM, and empirical studies were carried out to obtain the estimated value. Firstly, CVM questionnaire was designed by using the quadruple-bound dichotomous format and VOSL evaluation model was built on account of the principles of multinomial Logit model. Then a survey, targeting at private car drivers in Dalian, was conducted to investigate their transportation interests, and parameters calibration and significance tests were accomplished by means of Gauss. Finally, VOSL was estimated and influencing factors were analyzed. The study results indicate that VOSL in road traffic is estimated to be 2 310 800 yuan. The CVM questionnaire based on quadruple-bound dichotomous format performs better in simulating the process of market pricing, and the VOSL evaluation model based on quadruple-bound dichotomous method features higher accuracy. Moreover, VOSL in road traffic safety maintains a remarkably positive correlation with education background and monthly income of the family. © 2019 China Safety Science Journal
