DDSA Crash Tree Tool
The DDSA Crash Tree Tool allows users to generate crash tree diagrams based on the NHTSA Fatality Analysis Reporting System (FARS) or other crash datasets. Crash tree diagrams can be used as part of the systemic safety analysis process to help you identify and select the facility types where the focus crash types most frequently occur. The crash tree can have a number of different formats, depending on agency capabilities and data availability. The Systemic Safety Project Selection Tool includes additional information about the systemic safety analysis process, including examples of crash tree diagrams.
