State Highway Safety Offices (SHSOs), in conjunction with their state highway patrols and local law enforcement agencies, conduct multiple HVE campaigns throughout the year as countermeasures to road user crashes caused by impaired driving, lack of seat belt use, distracted driving, and speeding. These annual multiple campaigns are labor intensive for law enforcement agencies, and there are concerns about their effectiveness.
If research could demonstrate through evidence-based data that combined enforcement efforts are indeed effective, this would have positive resource impacts on SHSOs and their law enforcement partners.
The objective of this research was to develop a scalable evaluation framework and methodologies to determine the effectiveness of combined law enforcement/engagement for reducing crashes and their severity involving road user behaviors such as impaired driving, lack of seat belt use, distracted driving, and speeding.
