Crash Analysis

Using all available tools, knowledge, and technology, roadway safety is a key focus of the Transportation and Engineering Division. The process of identifying, evaluating, and planning safety improvements on public roadways begins with identifying where vehicular crashes have occurred. Jefferson County works with DiExSys, a roadway safety analytics consultant, to quality control and geolocate crash data provided to the county. Once this processing is complete, the data is used to identify crash patterns and develop crash mitigation projects.

Roadway Crash Analysis

A comprehensive evaluation of roadway and intersection crashes in unincorporated Jefferson County was completed in 2021. This analysis assists the Transportation and Engineering Division with implementing specific improvements to reduce the frequency and severity of crashes on county roadways.
