Advancing Transportation Safety in Colorado – A New Approach to Implementing a Strategic Highway Safety Plan
Colorado
Colorado introduced an annual action planning and refining process to SHSP implementation. The action plans allow Colorado DOT to respond to changes in transportation safety and adapt over the 5-year SHSP period.
Florida DOT identified hot spots for driver behavior across its District 2, allowing them to develop countermeasures to address poor behavior and crashes in those locations.
To identify locations with high Return on Investment for safety improvements, Florida DOT developed an advanced platform that integrates extensive data and safety metrics into one platform.
Don’t Wait, Be Proactive! Systemic Safety for Minnesota’s District Safety Plans
Minnesota
MnDOT updated road safety plans in every district with a systemic crash analysis. Analysis confirmed that higher crash densities and severe crashes occurred at locations with higher risk scores.
The MnDOT Safe System Approach Implementation Plan integrates the SSA into programming. Their process involves an internal SSA implementation workgroup, tools library, speed management guide, training, and updated technical guidance documents.
Predictive Safety Evaluation for Effective Infrastructure Planning
Texas
Using proprietary, AASHTO, and FHWA tools, TxDOT identified safety improvements, predicted, and evaluated safety performance in early stages of project development. The tools help every DOT project become a safety project.
Texas DOT’s combined CMF calculator tool calculates the combined reduction factor of multiple countermeasures (which provides HSIP funding documentation). The full tool is accessible to district staff.
A Comprehensive Approach for Friction-Enhancing Treatment Selection
Kentucky
Kentucky replaced a needs-based, hot-spot approach with a more precise, systemic, “solutions-based” approach to friction-enhancing treatments and improved pavement safety performance.
