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.

Roadway Crash Analysis

A comprehensive evaluation of roadway and intersection crashes in unincorporated Jefferson County is underway as part of the 2021 Safety Improvement Program. The comprehensive evaluation will be completed by the end of 2021. This analysis will assist Jefferson County Transportation and Engineering with recommending specific improvements to reduce the frequency and severity of crashes on county roadways.

Roadway crash analysis was also conducted in 2015. See 2015 Crash Analysis (PDF)

Jefferson County geolocated all crashes between 2011 and June 2019 for internal analyses. These data can be downloaded from the ArcGIS hub.
