Willingness to pay for road curviness and road type

Abstract This paper develops a method to value two road design features: curviness and road type (2-lane, 4-lane without a median, and 4-lane with a wide grass median). These features are linked to the safety of the road environment, providing information on how much individuals are willing to pay to reduce exposure to risk in the driving environment when trading between mixtures of curviness and road type. A stated choice experiment was designed in which car and truck drivers undertaking regional and inter-urban trips out of six New Zealand cities evaluated alternative trip profiles in terms of travel times and costs in addition to curviness and road type, and chose one of the trip profiles as the most preferred.
