                Data-Driven Approaches to Crime and Traffic Safety (DDACTS)
**Description:**
        Data-Driven Approaches to Crime and Traffic Safety (DDACTS) is the result of a partnership between the National Highway Traffic Safety Administration and the United States Department of Justice to develop data-driven, performance-based strategies for deploying law enforcement to address the competing priorities of reducing crime and preventing traffic crashes. Typically, law enforcement efforts focus on these issues individually. These approaches look at locations where enforcement can utilize best practices such as high visibility enforcement to work toward reducing crime, violations, and crashes simultaneously to extend resources and improve safety and well-being within communities.
DDACTS helps users to identify “hot spots,” or areas where there is a high incidence of both crimes and crashes, through use of mapping such as with geographic information systems. The guide outlines procedures and highlights operational considerations for diagnosing concerns, deploying effective enforcement strategies, and evaluating the effectiveness of enforcement activities to maximize the return on investment of resources. Seven guiding principles form a model for an effective program:

Partners and stakeholder participation.
	Data collection.
	Data analysis.
	Strategic operations.
	Information sharing and outreach.
	Monitoring, evaluation, and adjustments.
	Outcomes.The DDACTS website contains links to the operational guidelines, brochure, executive summary, evaluability assessment, and a toolkit.
