Public Transit Rideshare

The Public Transit Rideshare grant program—formerly the Vanpool Investment Program—supports rideshare programs at transit agencies across Washington.

Transit agencies use these grant funds to expand rideshare fleets, replace aging rideshare vehicles, and provide incentives to employers to increase ridership. The funding allows transit agencies to purchase rideshare vehicles with alternative fuel types, including low-emission plug-in hybrids and zero-emission all-electric vehicles.

Washington has the largest public rideshare fleet in the nation. Each workday, around 18,000 commuters travel in more than 3,000 rideshare vehicles. These rideshares improve air quality, lower greenhouse gas emissions, and reduce the number of cars on the road. The state's partnership with transit agencies began with 12 transit agencies in 2001 and has since expanded to 22 transit agencies across Washington.

Available funding

WSDOT anticipates awarding as much as $10 million in grant funding for the 2023-2025 biennium. This program is supported by state funding.

Match requirements

20 percent match is required for rideshare vehicle purchases for replacement, expansion, and vehicle equipment. No match is required for incentive-based projects.

Award prioritization

Tier 1

WSDOT will prioritize Public Transit Rideshare grant awards for:

  • Replacement rideshare-vehicle requests
  • Employer incentives

Evaluation criteria for replacement rideshare vehicles:

  • Must be beyond the Federal Transit Administration’s minimum useful life standards (i.e., four years or 100,000 miles).
  • Must be consistent with the applying agency’s transit development plan.

Transit agencies can apply for Public Transit Rideshare incentives to increase or maintain employee rideshare participation. Transit agencies can distribute incentives through employers.

Tier 2

WSDOT will give expansion vehicle and equipment replacement requests the lowest priority.

Scoring criteria

The selection committee will evaluate applications in four categories:

  • Quality of application/application completeness
  • Demonstration of need
  • Readiness to proceed
  • Financial proposal
