The TTIP is the list of Tribal transportation projects to be funded in the near term. The TTIP is defined in the Code of Federal Regulations (CFR) in Title 25, Section 170.5 (also known as the IRR Rule), as "a multiyear financially constrained list of proposed transportation projects developed by a Tribe from the Tribal priority list or the long-range transportation plan." According to 25 CFR 170.421, the TTIP must:
In comparison to the TTIP, the Tribal priority list includes all of the transportation projects the Tribe has identified including those without a funding source. According to 25 CFR 170.420, "the Tribal Priority List is a list of all transportation projects that the Tribe wants funded. The list (a) May or may not identify projects in order of priority, (b) Is not financially constrained, and (c) Is provided to BIA by official Tribal action, unless the Tribal government submits a Tribal Transportation Improvement Program."
According to 25 CFR 170.415, preproject planning is "part of overall transportation planning and includes the activities conducted before final project approval on the IRR Transportation Improvement Program (IRRTIP)." These activities include the following:
The BIA regional office must work cooperatively with Tribal, State, regional, and metropolitan organizations in regard to leveraging funds from non-IRR program sources and identifying other funding sources to expedite the planning, design, and construction of projects on the IRRTIP.
The IRRTIP is a multi-year list of transportation improvement projects programmed for construction by a BIA regional office with IRR program funds for the next 3-5 years. The IRRTIP contains eligible projects selected by Tribal governments from TTIPs or other Tribal actions (such as a tribal priority list). An approved IRRTIP is prepared for each State within the regional BIA office.
According to 25 CFR 170.422, the IRRTIP:
The Tribal control schedule is the implementing document for the TTIP. The Tribal government may elect to develop the Tribal control schedule under the Self-Governance contract or the Indian Self-Determination contract. The Tribal control schedule is an accounting and project management tool that is developed from the TTIP. It contains detailed project and task information for all projects identified in the TTIP. Project information is included in the BIA region control schedule without changing the total dollar amounts. The BIA control schedule is the BIA national compilation of all the regional control schedules (Federal Lands Highways [FLH] and FHWA Planning Glossary.
The TIP is a financially constrained 4-year program that outlines the immediate implementation priorities for transportation projects and strategies from a metropolitan area's long-range transportation plan. Federal statute (23 U.S.C. 134 and 49 U.S.C. 5303) requires that the TIP:
The Statewide Transportation Improvement Program (STIP) is a financially constrained list of transportation projects consistent with State LRTPs and planning processes as well as metropolitan plans. The STIP is developed under 23 U.S.C. 135 and 49 U.S.C. 5304. The Secretary of Transportation (U.S. Department of Transportation [DOT]) reviews and approves the STIP for each State. In addition, the STIP includes:
The IRR Rule is the regulatory (or regulation) reference to the Federal Title 25-Indians, Chapter I-BIA, Department of Interior, Subchapter H-Land and Water, Part 170 IRR program.
The FHWA statutory references for metropolitan and Statewide transportation planning are located in 23 U.S.C. 134 and 23 U.S.C. 135, respectively. The corresponding FTA references are found in 49 U.S.C. 5303-5304.
An MPO is defined in Federal Transportation Statute (23 U.S.C. 134b and 49 U.S.C. 5303c) as the designated local decisionmaking body that is responsible for carrying out the metropolitan transportation planning process. An MPO must be designated for each urban area with a population of more than 50,000 people (i.e., for each urbanized area defined in the most recent decennial census).
