Highway Performance Monitoring System (HPMS)
Another principal responsibility of ADOT's Data Section is administering a federal highway program known as the Highway Performance Monitoring System (HPMS). Required of each state and U.S. territory by the Federal Highway Administration (FHWA), the HPMS is the national database of highway information. Roadway extent, use, condition and performance data are collected by and for the states and submitted to the FHWA on an annual basis. From a national perspective, the FHWA's primary intent with this program is to provide Congress with a policy tool for major highway legislation and funding decisions.
Note: It is not possible to produce and post the previous year's statistics until July of the following year.
