Data-Driven Approaches to Crime and Traffic Safety (DDACTS) is a law enforcement operational model supported by a partnership among the Department of Transportation’s National Highway Traffic Safety Administration, and two agencies of the Department of Justice, the Bureau of Justice Assistance (BJA), and the National Institute of Justice (NIJ). DDACTS integrates location-based traffic crash, crime, calls for service and enforcement data to establish effective and efficient methods for deploying law enforcement resources. By identifying areas through temporal and spatial analysis that have high incidences of crashes and crime, DDACTS employs highly visible, targeted traffic enforcement to affect these areas. This model affords communities the dual benefit of reducing traffic crashes and crime, thus reducing overall social harm. Drawing on the deterrent value of highly visible traffic enforcement and the knowledge that crimes often involve the use of motor vehicles, the goal of DDACTS is to reduce the incidence of crashes, crime, and social harm in communities across the country.
