TTPTIP
TTPTIP means Tribal Transportation Program Transportation Improvement Program. It is a financially constrained prioritized list of transportation projects and activities eligible for TTP funding covering a period of four years that is developed by BIA and FHWA based on each Tribe's submission of their TTIP or Tribal priority list. It is required for projects and activities to be eligible for funding under title 23 U.S.C. and title 49 U.S.C. chapter 53. The Secretary of Transportation reviews and approves the TTPTIP and distributes copies to each State for inclusion in their respective STIPs without further action.
