Abstract

Abstract: This study investigates whether the expected travelling and parking behavior of autonomous vehicles (AVs) could lead to positive or negative societal impacts, both in terms of transport and the economy, which have been missed in previous studies. To capture transport performance and economic responses in the AV environment, we develop an integrated transport and economic equilibrium model that consists of the proposed autonomous traffic equilibrium and computable general equilibrium submodels. A modeling framework with a proposed solution methodology is presented to investigate the AV situation. A case study on Sydney, Australia shows that AV parking patterns can cause deterioration in traffic conditions with fewer completed journeys and greater travel time costs, which results in significant losses of social welfare. Furthermore, the disbenefit of AV travel behavior would become even larger with population growth.
