A Needs-Based Stated-Response Method to Predict Impacts of New Forms of Travel

This paper discusses a method to assess how people adjust their activity/travel patterns in response to changes in mobility options. Needs-based methods are employed in which multiple activity and travel episodes undertaken in service of a broader personal objective are analyzed as a pattern of linked behavior. The empirical study investigated how people would adjust their grocery shopping patterns if offered a one-way-usage carsharing service. A stated-choice/stated-adaptation survey instrument is proposed. Substantive findings relating to the impacts of one-way carsharing are discussed, as are the broader implications of viewing personal mobility behavior in this way.
