Subject(s): Abstract: The aim of this study is to elicit individual preferences for traffic risks and main objectives are fourfold: (i) to elicit a VSL (value of statistical life) and VSI (value of a statistical illness) for road, railway, air- and sea-traffic safety than can be used for policy purposes, (ii) to examine scope sensitivity between samples to examine the validity of the currently used ASEK values, (iii), to elicit equivalent monetary values for non-fatal risks that can be considered as a validation of the recent estimates in Olofsson et al. (2016), and (iv) to examine the difference in estimates between the DCE (discrete choice experiment) and CV (contingent valuation) methods. To examine objective (i) we will use DCE since that survey mode is best suited to examine the effect on transport mode on respondents’ WTP (willingness to pay). Objective (iv) will be achieved by creating identical surveys where only the WTP questions will differ between samples, i.e. respondents will either face DCE or CV questions. The design of the surveys in the DCE and CV will allow for objective (iii) to be achieved at a minimal additional cost for the whole project.Abstract: The aim of this study is to elicit individual preferences for traffic risks and main objectives are fourfold: (i) to elicit a VSL (value of statistical life) and VSI (value of a statistical illness) for road, railway, air- and sea-traffic safety than can be used for policy purposes, (ii) to examine scope sensitivity between samples to examine the validity of the currently used ASEK values, (iii), to elicit equivalent monetary values for non-fatal risks that can be considered as a validation of the recent estimates in Olofsson et al.
