Data-Approaches to Crime and Traffic Safety: Lessons Learned from the Smart Policing Initiative in Shawnee, Kansas

• In Event: New Findings from the Smart Policing Initiative

Abstract

This paper discusses the results of a study of the implementation of Data-Driven Approaches to Crime and Traffic Safety (DDACTS) by the Shawnee Police Department from July 6, 2010 until July 6, 2013. The research project examined the effects of DDACTS on vehicle theft, vehicle burglary, robbery, and vehicle collisions in a selected target zone. In addition, the study examined officer attitudes toward the implementation of DDACTS, as well business and resident perceptions. Overall, the results reveal that the DDACTS philosophy has been successfully adopted by the Shawnee Police Department: (1) analysis of officer focus group interviews shows evidence of a shift in culture and officer “buy-in” within the SPD; (2) surveys of businesses and residents in the target zone showed that a majority of respondents perceive a greater police presence and more traffic stops. Most respondents believe DDACTS has improved the quality of life in Shawnee. Most respondents rate the relationship between SPD and residents and businesses as very good to excellent. In addition, respondents support high-visibility, targeted traffic enforcement; and (3) the findings of an interrupted time series design with two comparison groups reveal a greater reduction in target crime and collisions in the DDACTS zone compared to the control zone and the rest of Shawnee, with no evidence of crime displacement. Moreover, there is statistical evidence of the crime reducing effect of DDACTS extends beyond the DDACTS zone.
