Determining the Effectiveness of Combined High Visibility Enforcement (HVE)
The National Highway Traffic Safety Administration (NHTSA) defines High Visibility Enforcement (HVE) as a universal traffic safety approach designed to create deterrence and change unlawful traffic behaviors. HVE combines highly visible and proactive law enforcement targeting a specific traffic safety issue. Law enforcement efforts are combined with visibility elements and a publicity strategy to educate the public and promote voluntary compliance with the law. NHTSA has funded several evaluations of combined enforcement programs with mixed results.
The 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 is 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.
The BTSCRP is seeking the insights of proposers on how best to achieve the research objective. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers’ current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the research objective.
The research plan should delineate the tasks required to develop a framework and methodologies to accomplish the research objective. At a minimum, the tasks should address the following:
- Review previous literature that have evaluated the effectiveness of HVE combined enforcement of reducing crashes and their severity involving impaired driving, lack of seat belt use, distracted driving, and speeding;
- Identify the approaches used to detect the road user behaviors to target enforcement strategies;
- Analyze the strengths and weaknesses of the process and outcome measures that are or could be used to determine HVE effectiveness;
- Develop an evaluation framework and methodologies that meet the objective; and
- Test the evaluation framework and methodologies.
