DDACTS Training

Data-Driven Approaches to Crime and Traffic Safety Training

Crime and Crash data plotted on a map
Data-Driven Approaches to Crime and Traffic Safety (DDACTS) integrates location-based crime and traffic data to establish effective and efficient methods for deploying law enforcement and other resources. Using GIS mapping to identify areas that have high incidences of crime and crashes, DDACTS uses traffic safety strategies that play a dual role in fighting crime and reducing crashes and traffic violations. Drawing on the deterrent of highly visible traffic engagement and the knowledge that crime often involves the use of motor vehicles, the goal of DDACTS is to reduce the incidence of crime, crashes, and traffic violations across the country. This has proven to be an effective, predictive, location-based policing approach to crime and traffic safety that delivers law enforcement services at the right place and at the right time.
