The Transportation Improvement Program (TIP) lists federally-funded projects that are ready to begin construction within the four-year TIP window. TIP's are adopted every two years.
The Annual Performance and Expenditure Report (APER) is a document produced each year that lists all work performed and deliverables produced during the specified fiscal year.
The obligated projects list details all federally funded projects authorized in the preceding fiscal year, including the amount of federal funds requested in the TIP, the federal funds obligated during the preceding year, and the federal funding remaining and available for subsequent years.
