Each entity that is awarded a grant or contract under this section shall report annually to the Department on the use of grant or contract funds received under this section to ensure that the awards made are expended in accordance with the purposes of this subchapter and the priorities developed by the Secretary.
The Secretary shall ensure that the research is consistent with the priorities established in the National Strategy for Public Transportation Security and is coordinated, to the extent practicable, with other Federal, State, local, tribal, and private sector public transportation, railroad, commuter railroad, and over-the-road bus research initiatives to leverage resources and avoid unnecessary duplicative efforts.
