The objective of the session is to determine the kinds of information we need to collect in order to understand vehicle ownership and usage uncertainties as the AV market develops, and to outline suggested research approaches for capturing reliable information.

This is a new workshop topic. It begins an interdisciplinary dialogue on how best to study the ways in which the market for AVs will develop. The advent of AVs could be truly transformative, but future acceptance and use are highly uncertain. Car ownership trends could change. Residential spatial patterns could change. The number of vehicle miles traveled (VMT) could increase or decrease, depending on how, when, and why people use AVs. Because AVs are not yet present in the traffic streams, with the exception of a few test vehicles, it is difficult to reliably predict future consumer demand. Any purported outcomes are just theoretical at this point. Basic questions need answers: How likely are people to use AVs? What are the factors that influence acceptance and intent to use? What is the appeal of AVs for people? In what ways might people change their current travel behavior because of access to AVs? Methods to collect and capture data need to ensure that the data are reliable. The choice of methods and the way in which they are implemented are largely determined by the research questions, but are also influenced by practical considerations such as ethics, budget and time. In this workshop, transportation planners, researchers and policy analysts will exchange their research experiences to date and explore best practice for the future.

For priority questions assigned to group:

Which can be answered immediately and which can only be addressed in medium to long term?

Which are already being effectively addressed and which are still highly uncertain?

How can we obtain necessary information for priority questions? Pros/ cons of different approaches
