Research Guides
Electric vehicles (EVs) are rapidly becoming commonplace on the nation's roadways, from passenger cars and light-duty fleet vehicles to transit buses and heavy trucks. This guide provides an introduction to electric vehicle issues for transportation agencies, with a focus on building out EV charging infrastructure and on understanding the needs of medium- and heavy-duty vehicles as electrification expands to these vehicle classes.

Research in Progress
NCHRP Synthesis: Strategies and Programs for Electric Vehicle Charging, National Cooperative Highway Research Program (NCHRP), start date: April 2021.
This synthesis will document current strategies and practices in use by state departments of transportation (DOTs) to facilitate and coordinate the provision and operation of EV charging facilities, including planning for medium- and heavy-duty vehicle charging. Topics include practices for EV charging infrastructure deployment, delineation of operating and maintenance responsibilities, public/private partnerships, procurement and contracting, pricing strategies, planning and prioritizing charging infrastructure, working with utilities, navigating funding complexities, evaluating program effectiveness, providing guidance or technical assistance to local governments, and policies for charging stations along state-owned roadways or in public rights of way.
