Accurate, meaningful, and timely safety information is needed for the optimization of highway safety programs. Geographical information systems for transportation (GIS-T) can supply those highway safety information needs. NCHRP Report 359 documents the development of a conceptual structure, implementation plan, and management guidelines for a GIS-T capable of supplying the highway safety information requirements for most transportation agencies. The North Carolina Department of Transportation (NCDOT) used those concepts and guidelines to develop a GIS-T that visually identifies and displays accident patterns on the North Carolina highway system and was the primary objective for the research and development effort described in this paper. A secondary research objective involved the testing and evaluation of the capability and suitability of Global Positioning System (GPS) technology to collect accident location data not presently contained in the NCDOT accident database. A final research objective involved a software engineering effort to develop a microcomputer based accident analysis system that would be compatible with GIS/GPS technologies and the existing mainframe accident analysis system.
