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.
Selected Resources
EV Planning Fact Sheet for States, U.S. Department of Energy (DOE), September 2021.
A summary of the U.S. DOE tools available to help states plan for EV charging infrastructure, including examples of state EV strategies.

Federal Funding Is Available for Electric Vehicle Charging Infrastructure on the National Highway System, Federal Highway Administration, April 2022.
This 16-page brochure outlines funding and financing programs available to help states, tribes, metropolitan planning organizations and others build out electric vehicle chargers along the National Highway System.
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.

About the Pooled Fund
The Transportation Research and Connectivity pooled fund study, TPF-5(442), is a consortium of state DOTs and other partners that supports the coordinated development of transportation libraries as well as research organizations without dedicated libraries. Study focus areas include communication and networking, digitization, research report accessibility, and developing online resource guides and a toolkit for non-librarians.
