2. Crash fatalities, 1990 - now Declines have leveled off
DUI accounted for 9,967 fatalities
Speeding accounted for 28%
Distraction accounted for 3,179
4,884 pedestrians and 726 cyclists killed
….and fatalities are just the tip of the crash problem. In addition to lives lost, traffic crashes caused 2.3 million serious injuries in 2014, and traffic crashes cost us $242 billion including lost productivity, medical costs, legal and court costs, emergency service costs (EMS), insurance administration costs, congestion costs, property damage, and workplace losses

3. What is DDACTS?
DDACTS is an operational model that uses the analysis of location-based crash, crime, calls for service and enforcement data to support effective and efficient deployment of resources.

4. DDACTS Goal
Reduce the incidence of crime and crashes in our communities. Reduce social harm.

5. Why use DDACTS? Crashes and crime often occur in close proximity
Crime/dangerous behavior often involves motor vehicles
Crashes significantly drain agency resources
Vehicle stops yield valuable intelligence
Agencies have increasing demands/decreasing resources
State highway safety programs AND fund recipients must deploy crash countermeasure resources based on data

7. Philadelphia Police Department
140 square miles
approx million people
21 police districts
6,250 sworn &
800 civilian personnel

8. Plan For Pilot Initiative
Utilize Traffic on “dark nights”
Focus on 25th District
Target areas of high traffic
Enforcement of traffic laws, DUI checkpoints, car stops

9. Philadelphia’s 25th District
High levels of social harm
Enthusiastic participation from district leadership
