State Highway System Performance

NEW DIRECTION FOR INVESTMENT DECISIONS

Developing the most effective and efficient transportation system requires that ADOT measure and analyze the system's conditon, and base decisions for roadway and other improvements on how well those projects or policies are expected to improve system performance. To assess performance, ADOT establishes goals for the system, targets levels to achieve, and measures to show how closely the targets are met.

Conducted annually, system performance assessment gives ADOT the information it needs to adjust funding allocated to perserving, expanding, and modernizing the state highway system. A more detailed performance analysis will be undertaken every five years when updating the state's long-range transportation plan.

ADOT’s planning efforts include developing a Five-Year Transportation Facilities Construction Program. ADOT’s Five-Year Program is a lineup of projects that is revised annually. It serves as a blueprint for future projects and designates how much local, state and federal funding is allocated for those projects. The Five-Year Program covers the construction budget for highways, transit, airports and highway-support facilities. The program focuses on multimodal forms of transportation. Funding for the Five-Year Program is generated by the users of transportation services, such as through the gasoline tax and the vehicle license tax.
