GIS-BASED CRASH REFERENCING AND ANALYSIS SYSTEM

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 geographic information system (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. The system was developed using the Highway Safety Information System (HSIS) for North Carolina for the area of Wake County. With built-in GIS functionality and the ability to customize the graphical user interface, ArcView GIS was chosen as the primary software for the system. The system includes a user interface that allows data to be entered, analyzed, and exported to other applications. It also features graphical displays. The analysis tools include five separate programs to evaluate crashes at designated spots or intersections, along specific roadway segments or strips, clustered around a specific roadway feature, or within a defined corridor. All of these tools combine to form a system that makes locating, editing, and analyzing crashes and other spatial data faster and more efficient.
