Research Center

The Research Center is a catalyst for innovation at the Arizona Department of Transportation. The Research Center engages in three major functions: administering the department's research program, managing the product approval program and maintaining a transportation library.


Projects administered by the Research Center focus on research that can be applied to improve ADOT processes and products. Research projects address the full range of topics of interest to the department.

Product Evaluation Program

The Approved Product List (APL) is updated every month. Changes to the APL must be approved by the ADOT Product Evaluation Committees: Materials Product Evaluation Committee (MatPEC) and Traffic Control Product Evaluation Committee (TCPEC).

Nathan M. Banks Memorial Library

The ADOT library contains books, journals and other publications including a broad range of transportation-related topics. The library catalog is available online.
