The culmination of new vehicle technology, greater competition in energy markets, and government policies to reduce pollution and energy consumption will result in changes to the personal vehicle marketplace. To measure future vehicle preferences, stated preference surveys have been the dominant approach. Prior research has been limited to a narrow focus of accelerating respondents to a hypothetical next vehicle purchasing decision without mimicking the marketplace’s influence on this decision. To explore marketplace influences, this project proposes to use a novel stated preference survey design to analyze vehicle purchasing behavior in a dynamically changing marketplace through the use of dynamic attributes and a six-year hypothetical time window. The survey is divided into three parts: household characteristics, current vehicles, and stated preference. The stated preference section presents respondents with various hypothetical scenarios annually over a future six-year period using one of three experiments. The experiments correspond to changing vehicle technology, fueling options, and taxation policy. Between scenarios, the vehicle, fuel, and policy attributes dynamically change to mimic marketplace conditions. A pilot web-based survey was performed during fall 2010. Mixed logit models showed that respondents responded in behaviorally realistically ways and that the survey design allowed for estimation of important parameters in vehicle choice. Respondents were able to depreciate their vehicles over the five-year hypothetical period and place tradeoffs on the features of vehicles and fuel types. The insights from the survey are also used to suggest refinements to the survey methods and areas for further research.
