TRB’s National Cooperative Highway Research Program (NCHRP) Research Results Digest 315: Centralized versus Decentralized State Procurement of Paratransit Vehicles for the Federal Section 5310 Program examines the procurement experience of states that directly and indirectly procure paratransit vehicles applying funds from the federal Elderly Persons and Persons with Disabilities Program (49 U.S.C § 5310). The report is designed to help states improve their current procurement processes or enable them to strategically consider alternative processes for acquiring vehicles for this program.
