Sensitivity of the urban transport system to the value of travel time savings for shared autonomous vehicles: A simulation study

摘要

Shared Autonomous Vehicle (SAV) services hold potential for disruptive impacts on urban transport systems. The value of travel time savings (VTTS) for these new services is assumed to be both significantly different from that of regular services and to have a strong impact on mobility behaviors. In this study, an agent-based transport simulation for Berlin, Germany, is used to investigate the sensitivity of the urban transport system to different VTTS for shared autonomous vehicle services. Simulation experiments are carried out for a range of plausible VTTS suggested by the literature. The simulation results indicate a strong impact of the VTTS on the modal split. Overall, further research is needed to further investigate behavioral parameters as well as the resulting impact on the urban transport system.
