Abstract:One area where a Geographic Information System (GIS) has yet to be extensively applied is in the analysis of crash data. Computerized crash analysis systems in which crash data, roadway inventory data, and traffic operations data can be merged are used in many States and municipalities to identify problem locations and assess the effectiveness of implemented countermeasures. By integrating this traditional system with a GIS, which offers spatial referencing capabilities and graphical displays, a more effective crash analysis program can be realized. The objective of this effort was to develop a crash referencing and analysis system within a GIS. This summary report describes the data bases used, the system design, the crash analysis programs used, and future developments. 4 p.
