The Arkansas GIS Office and Arkansas State Highway and Transportation Department (AHTD) are teaming up to coordinate the development of the next generation of road centerline data for the state. This work is in response to a federal mandate for an all public roads linear referencing system (LRS) and will impact road data maintenance and road funding in every jurisdiction. The AHTD currently maintains an LRS that includes all routes eligible for federal aid but not all public roads. The new centerlines will feature linear referencing system capabilities, as well as attributes describing jurisdictional assignment, surface type, and road design. When completed, local, state and federal transportation planners will have an accurate method for determining mileage of paved versus unpaved roads by jurisdiction and a systematically determined route, section, and log mile in the database for all public roads. All of this is meshed with the existing data that carries address range information and geocoding capabilities. This will allow one road file to serve many needs.
