Adoption of Shared Automated Vehicles as Access and Egress Mode of Public Transport

Abstract

Shared Automated Vehicles (SAVs) are a new road-based means of transport, usually small in size and capacity, with a relatively low operating speed and no (regular) possibility for the user to engage in any of the driving tasks. Past research focused on the implication of fully Automated Vehicles (AVs) in the transport sector, especially automated cars, analysing travel behaviour, network design, costs and infrastructure development. Such an extensive research on SAVs cannot be found, and most results are based on predictions for AVs acceptance instead, next to simulation studies, assumption-based models or stated choice experiments. In this paper we conduct a meta-analysis of existing literature, analysing the underlying factors that determine the adoption of SAVs. We identify the factors that have a positive effect, the ones that have a negative effect and the ones for which the effect is still unknown. Subsequently, we propose a conceptual scheme to illustrate the links between the public transport network components and the implementation of SAVs, defining a set of research questions that can help integrate SAVs in the public transport system.
