The Transportation Improvement Plan (TIP) is prepared each year by the National Capital Region Transportation Planning Board (TPB), which is the designated metropolitan planning organization for the Washington region. As a product of the urban transportation planning process, it outlines the staged development of the area's financially-constrained Long-Range Transportation Plan (CLRP), with priority projects selected for programming by the TPB, the states, and the transit agencies presented in the first year of the six-year program. The TIP is updated by state, regional and local transportation agencies each year. The TIP serves several purposes:

• expresses the region-wide intent to implement specific facilities and projects during the upcoming six-year period;
• provides a medium for local elected officials, agency staffs, and interested members of the public to review and comment on the priorities assigned to the selected projects;
• satisfies one of the requirements of FHWA and FTA for the continuing transportation planning process of this region (necessary for certification to insure continued federal financial assistance for Washington area transportation improvements); and
• establishes eligibility for federal funding for those projects selected for implementation during the first program year, known as the Annual Element of the program.
