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.
Improving Rural Intersection Safety and Efficiency with Dynamic Dilemma Zone Protection: Alabama Pilot Study
Alabama
Rural high-speed intersections in Alabama experienced several benefits, including 24-35% fewer red light-runner crashes, in a pilot of CWA (continuous wide area) sensors used in a dynamic DZP (dilemma zone protection) system.
AASHTOWare compares and contrasts three methods for safety improvement location identification: 1) crash prediction model, 2) expected crash frequency exceeding threshold, and 3) crash prediction model + systemic safety characteristics.
TIM Training and Technology Supporting Post-Crash Care
FHWA
FHWA highlights efforts to support EMS through TIM technology, training, on-the-scene tools, and vehicles. Many states have introduced TIM training and technology to bolster post-crash care.
Traffic Incident Management Strategies for Electric Vehicle Fires
FHWA
With an increasing number of electric and hybrid vehicle fires on roadways, FHWA developed a State of Practice report to support roadway safety and incident management in EV fires.
Data-Driven Calibration of Safety Performance Functions Using Optimization Techniques
Georgia
Georgia worked to calibrate SPFs for rural and urban roadways to optimize and refine SPF models. GDOT found that a combination of models for outlier detection and optimization yielded the most robust SPFs.
