Transportation Improvement Program


The Transportation Improvement Program (TIP) identifies the transportation projects and strategies that CRTPO and NCDOT plan to undertake over the next ten years. All projects receiving federal funding must be in the TIP. The TIP is the region’s way of allocating its transportation resources among the various capital and operating needs of the area, based on a clear set of short-term transportation priorities.

The TIP:

  • Is updated at least every two years;
  • Is realistic in terms of available funding and is not just a "wish list" of projects. This concept is known as fiscal constraint;
  • Conforms with the State Implementation Plan (SIP) for air quality (CRTPO is classified as nonattainment for ozone);
  • Is approved by the MPO and the governor; and
  • Is incorporated directly, without change, into North Carolina’s State Transportation Improvement Program (STIP).

The process by which the NCDOT STIP is developed is known as NCDOT Prioritization.

The CRTPO held a public comment period on the 2018-2027 TIP, the 2040 MTP Amendments and an air quality conformity determination from July 9 until August 16, 2017. Public comment summaries and responses can be viewed by clicking here.


2040 Metropolitan Transportation Plan Amendments
MTP Amendments
Following the release of the DRAFT STIP by NCDOT, a series of amendments to the 2040 Metropolitan Transportation Plan (MTP) Amendments were required to ensure that the plan conforms to CRTPO’s Draft TIP. Amendments were required to the 2040 MTP for the following reasons:

  • To add new projects that were not previously in the 2040 MTP, but were identified in the DRAFT TIP

  • To move projects to a different horizon year in the 2040 MTP

  • To change project extents in the 2040 MTP to match the limits in the DRAFT TIP.

  • The TIP is a subset of the 2040 MTP and both documents should match.

The TIP is a subset of the 2040 MTP and both documents should match.

Air Quality Conformity Determination

The Clean Air Act requires the CRTPO to demonstrate that its Transportation Improvement Program (TIP) and Metropolitan Transportation Plan (MTP) conform to the Statewide Improvement Program (SIP). Transportation conformity is an important part of the CRTPO’s planning process. The Air Quality Conformity Determination Report can be viewed here and certifies that the projects proposed within the 2018-2027 TIP and 2040 MTP are within the prescribed limits for air quality within the Charlotte region.

TIP Financial Plan

Federal regulations require Metropolitan Transportation Plans (MTPs), Transportation Improvement Programs (TIPs), and Statewide Transportation Improvement Programs (STIPs) to be “fiscally constrained.” The requirement for fiscal constraint is met through the preparation of financial plans, the requirements for which are contained in the joint FTA/FHWA regulations for Statewide and Metropolitan Transportation Planning (23 CFR 450). These regulations specify that the financial plan must be fiscally constrained for the first four program years of the TIP.
