Regional Pavement Management System

Pima Association of Governments, which owns no roadway infrastructure, coordinates a Regional Pavement Management System to ensure compatibility of pavement management databases and information collection techniques among PAG's member agencies.

The system provides member agencies with the appropriate tools and data to assess the deterioration of publicly owned roadways and other roadway infrastructure. Accurate management of our region's infrastructure assets is essential for allocating and optimizing available maintenance funding.


PAG coordinates regional pavement data collection through the use of a shared resource, the Automatic Road Analyzer (ARAN) pavement management van. The ARAN van is operated by the City of Tucson and collects consistent and accurate roadway data, such as pavement condition, roadway ride quality and precise location information of specific features on or near the roadway. The ARAN van uses a variety of sensors, a sub-meter global positioning system, video and machine vision systems, and computers. More information about the ARAN van housed and maintained by the City of Tucson is available at
