Data for Proactive Road Safety: Continuous Pavement Friction Measurement

Kentucky
Pavement Friction Management (PFM) using Continuous Pavement Friction Measurement (CPFM) is a proactive approach for managing pavements for safety throughout the roadway lifecycle. Taking a lifecycle approach to designing, specifying, and maintaining friction performance saved Kentucky more than $1 billion annually and reduced fatal and severe crashes by up to 24%.

Method for Short-Term Network Screening

Iowa
Iowa DOT's short-term network screening method identifies freeway segments most likely to have excess crashes in coming weeks, which helps prioritize emergency response and enforcement. Seasonal conditions (weather, animal crossings) may be factored into crash risk. The method can also help with the design of effective countermeasures.

Data-Driven Strategies Using Predictive Modeling and Interactive Dashboards

Iowa
Since traffic safety projects often yield varying impacts on safety performance, Iowa DOT established a robust system to track crash histories related to safety projects, which is essential to assess project effectiveness, efficiency, and return on investment. The system is helpful to site identification, safety issue diagnosis, and countermeasure evaluation.

B/C Analysis Using Conflict Detection for Midblock Pedestrian Crossings

Georgia
Georgia DOT used conflict detection to assess pedestrian safety at midblock crossings in Jesup, Georgia, allowing for safety concerns to be assessed in further detail than utilizing crashes alone. Using proactive conflict detection data and reactive observed crash data, pedestrian safety projects can be economically justified and prioritized.

Advancing Work Zone Safety: Real-Time Digital Workers

Delaware Iowa Louisiana Nebraska
Work zones pose significant dangers to both workers and drivers. Traditional notification systems often fail to provide real-time information. DOTs are using platforms like EDOT to integrate various data streams and provide automated, real-time alerts about active work zones, fostering collaboration and more comprehensive safety measures.
