Transportation Improvement Program

The Transportation Improvement Program (TIP) is a short-range (3-5 year) capital improvement program (budget) of transportation projects consistent with federal regulations and area policies and strategies. The TIP lists all projects for which federal funds are anticipated, along with non-federally funded projects that are regionally significant. The TIP represents the transportation improvement priorities of the region and is required by federal law. The list includes roadway and public transit projects. For more information contact Toni Tisdale, (208) 475-2238.

COMPASS produces a regional TIP for both the Northern Ada County and Nampa Urbanized Area and updates the document annually. The list of TIP projects must be endorsed by the COMPASS Board. The U.S. Department of Transportation requires that all projects in the TIP be derived from an approved long range transportation plan, meet air quality requirements and be financially constrained to the amount of funds that are expected to be available. The TIP shows the estimated costs and projected construction schedule of transportation projects. The TIP brochure describes in more detail how the TIP is developed. (English/Español)

The Idaho Transportation Department’s Idaho Transportation Investment Program (ITIP) and Ada County Highway District’s Integrated Five-Year Work Plan provide information on additional transportation projects not included in the TIP.

The TIP shows how projects correlate with CIM performance measures. This reporting not only allows a reader to easily see how individual projects help achieve CIM goals, but it also provides additional accountability for the project sponsor and decision-makers, as they must be able to clearly demonstrate the relationship between projects and CIM goals.

Transportation Service Coordination Plan for Ada and Canyon Counties (3D LMMN Plan)

Transportation Services Coordination Plans are developed to maximize existing public transportation services, increase the efficiency of those services, and secure additional funding for these services. Specifically, they fulfill a federal requirement to develop a plan to access applicable Federal Transit Administration funds.
