Because land use affects travel patterns, AMATS maintains an inventory of land use (see 2005 Land Use Map (8,809k pdf)), which the agency uses as a reference tool in planning transportation improvements. AMATS has completed an inventory of its study area every five years since 1970. The inventories are comprised of acreages for residential, retail, wholesale, industrial, transportation and utilities, public and open space. The inventories also consist of non-residential square footage, population, employment and auto ownership.

In October 2008, AMATS completed updating and converting its 2005 land use inventory to ArcView GIS. An inventory is available for the entire AMATS area.
