Three revolutions are underway in urban transportation around the world: vehicle electrification, automation, and shared (on-demand) mobility. The manner in which each of these unfolds, and how they interact, will have major implications for urban transportation energy use and CO2 emissions over the coming decades. Our modeling work suggests a wide range of possible impacts and a strong need to pursue policies that move these revolutions in societally optimal directions, notably toward large-scale sharing (pooling) of rides. This Commentary summarizes and extends this work.
