The Transportation Improvement Program (TIP) is a subset of the Long Range Transportation Plan (LRTP). It is a document that covers a 4-year timespan that outlines the transportation projects within the region. The projects varies from region to region, but can include, but not limited to, highway or roadways, sidewalks, bikeways, bridges, and/or public transportation services or facilities. Like the LRTP, the TIP must be financially constrained.
