Roadway Inventory Management Section (RIMS)
The Roadway Inventory Management Section of ADOT's Multimodal Planning Division (MPD) is responsible for collecting, producing and maintaining a wide array of highway extent, use and performance information about Arizona's public road and street network. Primarily focusing on the 6,722 (2010) centerline miles of the state highway system, the principal charges of RIMS are to collect and disseminate traffic volume data, maintain related traffic monitoring equipment, perform photo highway inventories, collect global positioning system (GPS) data, and maintain an annual log of length and geometric information on each state highway as a result of completed construction projects. Additionally, the section is responsible for administering the Federal Highway Administration's Highway Performance Monitoring System (HPMS) Program - a comprehensive source of information about vehicle mileage and travel estimates for all of Arizona's public roads and streets. Information collected by this section is used extensively in and out of the Department to develop policies and support decisions related to public highway funding issues or private investment options.
