The Statewide Transportation Improvement Program (STIP) is a four-year planning document that lists all projects expected to be funded in those four years with Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) participation. The STIP must be developed according to Title 23 of the United States Code. The STIP, which is multimodal, includes investments in various modes, such as transit, highways, and bicycle facilities. The STIP is the venue for implementing the goals and objectives identified in regional and State long-range transportation plans.
The regional Transportation Improvement Programs (TIPs) are similar documents prepared by each metropolitan planning organization (MPO) for its individual region. The STIP must include each MPO's TIP without modification, be fiscally constrained and be assessed for impacts to air quality. Without inclusion in the TIP/STIP, a project is ineligible for FHWA or FTA funding.
