Computerized crash analysis systems in which crash data, roadway inventory data, and traffic operations data can be merged are used in many state and municipalities to identify problem locations and asses the effectiveness of implemented countermeasures. By integrating this traditional system with a geographical information system (GIS), which offers spatial referencing capabilities and graphical displays, a more effective crash analysis program can be realized. The FHWA GIS Safety Analysis Tools include five separate programs to evaluate crashes:
- Spot/Intersection Analysis
- Strip Analysis
- Cluster Analysis
- Sliding-Scale Analysis
- Corridor Analysis
For an overview of the GIS Safety Analysis Tools, see the Summary Report, GIS-Based Crash Referencing and Analysis System [PDF].
