Autonomous Vehicles and Public Transportation

Abstract

Full automation Autonomous Vehicle technology (AV), is announced as possible, and safe, in the future. Widespread deployment would deliver sharp reductions in accidents and parking needs, two boons for society, particularly in cities. AV’s role in total travel, hence congestion, energy and emissions is ambiguous, possibly negative. Relieving drivers from driving, better serving those unable to drive, will strain the system. Unless shared AVs reduce vehicle ownership (difficult, uncertain), increase sharing and do not tempt people away from Public Transportation – calling for planning, taxing and subsidizing. Otherwise, less cost, more convenience might double traffic.
