About the research

High Visibility Enforcement (HVE) promotes voluntary compliance with traffic safety laws through a combined approach using enforcement strategies (i.e., enhanced patrols), visibility elements (i.e., specially marked squads, electronic message boards), and public outreach.

The goal of this research is to develop a scalable evaluation framework and methodologies to determine the effectiveness of HVE campaigns to reduce crash frequency and severity involving road user behaviors such as impaired driving, lack of seat belt use, distracted driving, and speeding.
