A Stated-Choice Experiment on Mode Choice in an Era of Free-Floating Carsharing and Shared Autonomous Vehicles

New forms of shared mobility such as Free-Floating Carsharing services and Shared Autonomous Vehicles have the potential to change urban travel behaviour. In this paper a stated choice experiment on mode choice among a sample of the Dutch urban population is presented, in which the particular features of free-floating carsharing and shared autonomous vehicles in comparison to private vehicles and public transportation are examined. The most explanatory and robust mode choice models were obtained by estimating nested logit models with two categories capturing vehicle automation or vehicle ownership, and a nested logit model with three categories capturing who is performing the driving task (the commuter, a human driver or an autonomous vehicle). Interpreted as mode preference, the alternative- specific constants of the utility functions reveal a strong impact of vehicle automation on mode choice: while early adopters of mobility trends show a clear preference for shared autonomous vehicles over all other modes, normal and late adopters show a clear aversion towards this mode. In terms of vehicle sharing, no preference of sequentially shared modes over a simultaneously shared bus could be determined. Participants currently not having access to carsharing services show a stronger preference towards free-floating carsharing than the early adopters subscribed to carsharing.
