Abstract

There is currently little info on what to expect regarding ride-pooling in shared automated vehicles (SAVs). Who will be willing to share rides, with whom, and under what conditions? This report details the efforts and results funded by two seed grants that converged on these questions. A broad-based literature review and review of automated vehicle (AV designs) leads to the articulation of potential risks and benefits of the pooled SAV experience and potential design solutions and supports, respectively. Risks could be related to compromised personal space, security, control, and convenience. Design features that might mitigate these risks include large windows to afford a high degree of visibility into and out of the vehicle, spacious seating and legroom (relative to larger shared vehicles like buses, trains, and planes), access to a remote human administrator who can observe inside the vehicle at all times, easy means to program private stops that are nearby one’s ultimate origins and destinations (to maintain privacy), and options for large groups or associations to “own” a particular vehicle (e.g., a female only SAV). The benefits of pooled SAVs could be related to restoration and social capital. Design features that could support these benefits include themed interiors; quizzes, games, and ambient entertainment; augmented reality windshields; flexible seating allowing riders to face each other; accommodations for food and drink; ensuring broad access; and making SAVs a canvas for local art. The report ends with a proposed research agenda highlighting the importance of qualitative engagement with consumers to understand the issues related to switching to pooled SAVs from various dominant travel modes (e.g., private cars, ride-hailing, public transit); leveraging analogous modes (e.g., pooled ride-hailing) to study the potential of pooled SAVs; and conducting experiments to understand the influence of various features of the pooled SAV experience that will impact consumer adoption. This report can inform SAV designers, policy-makers, private transit service providers, and other stakeholders about behavioral and design factors that will impact the uptake of pooled SAVs.
