A pavement management system (pms) should address all aspects ofthe pavement management process from planning and programming through project development and implementation. Geographic information system (gis) technology can be used to expand and enhance each of these pms components. A gis can be designed as a platform on which the pms is built and operated. Such a system is designated a pms/gis. Theimportance of a variety of spatially integrated data to pavement management decision making is examined. Each component of the pms process is explored and the applicability of gis technology to this particular component is discussed. This process results in the identification of a set of functions required for an effective pms/gis. Thesefunctions include thematic mapping, flexible data base editing, formula editing, statistics, charting, matrix manipulations, network generation, and integrated models and algorithms. The results are based on research for integrating gis technology and pavement managementmodels. All reported concepts and results have been incorporated into transcad, the gis for transportation software.
