Electric vehicle adoption and the associated challenges, including equity, was a key topic of discussion among UMD researchers who showcased their work at this year’s Transportation Research Board (TRB) annual meeting in Washington, D.C. 

EVs generally come with a higher price tag compared to their conventional gas-powered counterparts, and ownership is often concentrated in relatively wealthy areas, a trend that influences the distribution of charging stations. Lower income communities, including many that are predominantly Black, thus risk being left out of the EV revolution.

In a paper presented at TRB, UMD Professor Qingbin Cui (civil and environmental engineering) and his co-authors–Michigan Technological University Assistant Professor Abdolmajid Erfani and Federal Highway Administration P3 Program Manager Patrick DeCorla-Souza–propose community crowdfunding as a way of overcoming these disparities. Under their plan, ownership of charging stations would be offered to members of Historically Disadvantaged Communities (HDC) at a steep discount, thus incentivizing not only investment but upkeep.

“By providing ownership opportunities, community members become active stakeholders in the project, aligning their interests with the success and sustainability of the EV infrastructure. This approach not only fosters a sense of ownership and pride but also ensures that the benefits of the charging stations directly flow back to the community,” the authors suggest. The paper presents and evaluates a hypothetical test case in Montgomery County, concluding that rates of returns for the community investors could be as high as 68%. ‘

The research was part of a successful application by the Maryland Clean Energy Coaltion–which includes the UMD-based Build America Center, directed Cui–for a $15 million grant that will support deployment of equitable charging infrastructure.

In a separate TRB panel presentation, meanwhile, UMD doctoral student Nneoma Ugwu examined a burgeoning equity issue associated with EV adoptionxf—namely, the erosion of funding needed for road upkeep, which has traditionally been financed through gas taxes.

Users of fuel-efficient vehicles pay less gas tax, and in the case of EV users may pay no gas tax at all. Because these vehicles are more expensive and tend to be owned by more affluent drivers, the burden of funding is now falling disproportionately on disadvantaged communities, while a mounting transportation funding crisis threatens upkeep.

A Road Usage Charge system, incorporating mileage-based fees, could lay a more sustainable and equitable foundation for future funding, Ugwu and co-presenter Jeffrey Kupko (Michael Baker International) suggested.The panel, "Equity Considerations in Road Usage Charging," was facioitated by Susan Binder, Principal, Integrated Planning & Policy, Cambridge Systematics.

In all, UMD researchers presented more than 40 papers and posters at TRB 2024, covering a wide gamut of transportation engineering studies.
