The Federal Transit Administration (FTA) is seeking applied research projects to enhance the safety, reliability, efficiency, and accessibility of U.S. public transportation. This unrestricted solicitation is open to any responsible source except Federal Government-owned businesses, and teaming is encouraged. Individual awards are expected to range between $150,000 and $500,000, subject to fund availability. Projects should target technology readiness levels 3 through 6, with preference for proof-of-concept testing at TRL 3, and proposals including transit operator partnerships and cost sharing are favored.
