Electric vehicles (EVs) promise for positive impacts on energy security, climate change, and public health which are yet to be entirely manifested (especially in the U.S.) through widespread EV adoption. To increase EV market penetration, this line of research explores EV adoption behavior by designing empirical studies including: (i) data collection (such as first-of-a-kind national household retrospective vehicle survey conducted by our group); and (ii) developing novel modeling frameworks on dynamics of household vehicle ownership decisions such as vehicle transaction, fuel type, use, and ownership level. By mapping the households' decisions to their demographic attributes, travel patterns, and attitudes, the research outcome is useful to inform policy makers, for instance, about the impacts of EV charging infrastructure on EV adoption behavior and efficiency of national- and state-level policy incentives (e.g., tax exemption, free parking, and access to exclusive lanes for high occupancy vehicles).
