Crash Analysis and Data

The goal of roadway safety in Jefferson County is to minimize crashes and resulting deaths and injuries on county roadways using all available tools, knowledge, and technology.

The process of identifying, evaluating, and planning safety improvements on public roadways begins with identifying where vehicular crashes have occurred. Jefferson County partners with DiExSys, a road safety analytics company, to quality control and geolocate crash data provided to the county in crash reports. Once this processing is complete, the data are used to identify crash patterns, to develop crash mitigation projects, to perform county-wide planning, and to identify behavioral patterns.
