The autonomous vehicle (AV) technology holds great promise for improving efficiency of traditional vehicle sharing systems. In this paper, the authors examine a new vehicle sharing system using AVs, referred to as autonomous vehicle sharing and reservation (AVSR). In such a system, travelers can request AV trips ahead of time and the AVSR system controller will optimally arrange the AV pickup and delivery schedule and trip chains on the basis of the recorded trip demand requests. A linear programming model is proposed to efficiently solve for optimal solutions for AV trip chains. Case studies show that AVSR can significantly increase vehicle use rate (VUR) and consequentially reduce vehicle ownership significantly. In the meantime, it is found that the actual vehicle miles traveled (VMT) incurred by AVSR systems is not significantly more than that of conventional taxis, despite inevitable empty hauls for vehicle relocation in AVSR systems. This indicates that the increased VMT incurred by relocating sharing vehicles can be partially compensated by the reduction in required AV fleet size. The results imply potential huge benefits from AVSR systems on improving mobility and sustainability of our current transportation systems.
