Geographic Information Systems for Highway/Sign Maintenanceby Michael R. Martin, Patton Harris Rust & Associates, Fairfax, United States,
Abstract: Geographic Information Systems (GIS) can be a key element toward achieving improved management of all transportation facilities for municipal and state Departments of Transportation (DOT) everywhere. Highway maintenance increasing costs, limited financial resources of state/local governments, and recent federal management systems requirements in the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) have increased the need for a more sophisticated decision/design support mechanism. This paper describes how existing highway maintenance needs evaluations can be dramatically improved with the graphic display and data manipulation capability of GIS. The paper investigates two such maintenance areas: pavement management systems and sign management systems.
