Data-Driven Approaches to Crime and Traffic Safety
DDACTS
DDACTS is an operational model that uses the integration of
location-based crime and traffic data to establish effective and efficient methods for deploying
law enforcement and other resources.
DDACTS Goal
Reduce the incidence of crime, crashes and traffic violations in a community
Reduces Social Harm
Why DDACTS?
● Increasing Demands and Limited Resources
● Conflicting / Competing Demands for Service
● Crime and Crashes Often Occur in Close Proximity
● Crimes Often Involve a Motor Vehicle
● Vehicle Stops Can Yield Criminal Identification and Arrest
DDACTS Advantages
Collaborative EffortGrounded in Community-Oriented Policing
Evidence Based Problem-SolvingFocused Area for High Visibility
EnforcementEnsures Accountability
Fewer Ethical and Legal Concerns
National Organization of Black Law Enforcement Executives
“If the data analysis reveals that criminal activity and traffic crashes
occur at a specific place within a community, then it is at that place
that law enforcement activities need to be focused. A non-biased, data-driven approach to crime and traffic
safety delivers law enforcement services at the right place and at the
right time.”Joseph A. McMillan, NOBLE President
