Deploying Level 4 Shared Automated Vehicle Services on ODD-compliant Subnetworks: a Multimodal Analysis

Abstract

This abstract reports on a case study in which a station-based shared automated vehicle (SAV) service would be deployed in Leuven, Belgium. The vehicles are assumed to operate on a level 4 of automation and are restricted to drive on a subnetwork compliant with the operational design domain (ODD). The scenario is evaluated using a multimodal equilibrium assignment model in which the SAV market share is assumed dependent on its level-of-service (LOS) and competition with other modes. The model uses a macroscopic modelling approach based on the traditional 4step transport model. However, it is integrated with a microscopic modelling approach to properly model the SAV service supply. Results suggest that, in the scenario considered, the new service would serve a market share of 21.0% of which most customers are former car users and passengers. Further, vehicle-hours-travelled (VHT) and vehicle-kilometers-travelled (VKT) increase by 23.6% and 1.7%, respectively.
