The U.S. Department of Transportation’s Federal Highway Administration (FHWA) on Aug. 30 announced eight state transportation projects would receive $14.2 million in grants to assess alternative revenue mechanisms under the Surface Transportation System Funding Alternatives (STSFA) program.

The projects test various methods of collecting state transportation revenue through road usage charges. In addition to exploring new technologies and methods to charge a fee on vehicle-miles traveled (VMT), the programs will also address ways to achieve public support and improve privacy protection and reliability.

Of the seven states that received grants , California and Oregon – which received two – already have VMT pilot programs in place. In addition, Delaware’s grant will be used to participate in the I-95 Corridor Coalition, which includes several East Coast states that are working together to test a VMT fee, among other projects.

The STSFA grant program was established under the Fixing America’s Surface Transportation (FAST) Act of 2015.
