Crash Analysis is a solution that helps state transportation departments standardize their road segment datasets and assign roadway crash locations to specific roadway segments. Risk maps created from crash analysis results can help inform decisions regarding safety improvement priorities or crash mitigation measures.

Crash Analysis includes three tools that help prepare your dataset with the necessary attributes, merge road segments together based on certain parameters, assign crashes to individual road segments, and create four standard crash risk maps.


Crash Analysis requires specific software.
