Abstract: Regional evaluation of transportation lifeline facilities which may be impacted by seismic and other natural hazards is of great concern for purposes of emergency planning and response and for establishing priorities for maintenance and retrofit if an unacceptable risk is found to exist. An important tool which can aid in carrying out such an analysis is the use of computer-based Geographic Information Systems (GIS). Use of a GIS system to perform interactive regional risk analysis for bridges is described to illustrate the procedures involved. The analysis utilizes the GIS system as a platform to integrate the wide variety of information and computational procedures needed to evaluate the impact of a user selected earthquake on the total system of bridges in a region. Erie County, NY is utilized as a demonstration area for regional analysis which is representative of conditions existing in the eastern U.S.
