High-visibility enforcement (HVE) campaigns are effective in improving traffic safety. However, many agencies face challenges in evaluating their impact due to limited resources, data, and analytical expertise. TRB hosted a webinar on Wednesday, November 12, 2025 from 1:00 PM to 2:00 PM Eastern that introduced practical tools to assess these campaigns. Presenters described frameworks and methodologies for evaluating HVE effectiveness, including data visualization tools, before-and-after analyses, traditional statistical analyses, and spatial/temporal analyses that identify trends and relationships. Presenters also discussed crash modification factors developed through the project to help agencies better understand the safety impacts of their enforcement efforts.
This webinar was based on BTSCRP Research Report 10: Combined High-Visibility Enforcement: Determining the Effectiveness.
This webinar was sponsored by TRB’s Behavioral Traffic Safety Cooperative Research Program.
The slides are available. Please visit the webinar details page to access the recording.
