Transportation Safety

One of the main goals of the Transportation and Engineering Division of Jefferson County is to ensure our roadways are both safe and efficient by using a variety of tools, resources, and technology. The process of identifying, evaluating, and planning safety improvements on public roadways within unincorporated Jefferson County consists of community input, analyzing historical traffic data, and evaluating the current and future needs of our roadway system.

Safety Improvement Projects

Throughout Jefferson County, Transportation and Engineering is constantly working to identify areas where safety improvements will have the greatest positive impact for all roadway users. These locations then get added to our Safety Improvement Program (SIP) projects list where we work towards a solution. This section will highlight recently completed safety improvement projects as well projects that have been planned. 

Crash Analysis

Using a roadway safety analytics tool (Vision Zero Suite), Jefferson County collects and analyzes data pertaining to crashes on county-maintained roadways. The county then uses this tool and data to help guide decision-making related to safety improvements. This section will highlight the goal of safety and how we work towards reducing crash potential using crash data from within unincorporated Jefferson County between 2011 through 2021.  

Vision Zero

Jefferson County supports the goal of Vision Zero. Vision Zero is used in municipalities around the world and has been adopted by several communities in the Denver region. This safety-oriented approach focuses on a core principle that traffic fatalities and severe injuries on our roadways are preventable. With a proactive response that accounts for human error and roadway hazards, we can use data, technology, and collaboration to work towards safe mobility for all roadway users.

Traffic Calming

Jefferson County is responsible for maintaining over 3,500 miles of roadways. To ensure that we are providing an appropriate balance of safety and efficiency, a traffic calming toolkit is being developed to highlight different methods that the Transportation and Engineering Division considers for each unique application. This toolkit will explain when each traffic calming countermeasure, or “tool”, may be warranted as well as the benefits and drawbacks associated with each. Common tools currently used on county roadways include speed humps, medians, and additional striping. The Traffic Calming Toolkit will expand upon these existing treatments.
