The Philadelphia Foot Patrol Experiment
On the invitation of the Philadelphia Police Department, police and academic researchers worked together to plan the Philadelphia Foot Patrol Experiment as a randomized control trial. 60 violent crime hot spots were targeted during the summer of 2009, and after three months violence had reduced by 23 percent compared to comparison areas. Analysis of the results found little displacement, but did find at threshold level for effectiveness. Recent follow-up work has further illuminated the long-term effects of the study.

The Crime Reduction Effectiveness of CCTV
Newspaper accounts suggest that CCTV cameras are being implemented at a rate never seen before. Yet there has been a lack of high quality, independent evaluation studies, and only one significant study in the US, conducted over a decade ago. Drs Ratcliffe and Groff are currently working on an NIJ-funded study to evaluate the crime reduction impact of over 100 CCTV cameras in Philadelphia, PA, – an ongoing NIJ-funded large-scale, multi-method, quasi-experimental research study.

The Smart Policing Initiative The Smart Policing Initiative
(SPI) is a collaborative between a number of police departments in the US
and a research partner. In Philadelphia, the Philadelphia Police Department has partnered with Temple University and researchers from CSCS. The project is funded by the Bureau of Justice Assistance. In this project, we are testing a range of solutions to serious crime problems in the city, including; foot patrol,offender-focused activity, and problem-oriented policing.

Predictive Modeling of Long and Short Term Crime Risk
This ongoing project will create a free software tool that will enable police departments to use their geocoded crime data in combination with freely-available census data to create micro-spatial estimates of future criminal activity at the local block level. Working with Azavea, an innovative Philadelphia-based GIS company, Drs Ratcliffe and Taylor are developing a methodology to combine long-term risk prediction from underlying socio-demographics with event-created near-repeat risk.
Faculty: Jerry Ratcliffe, Ralph Taylor More information about CSCS will be available shortly. If you have any questions in the meantime, please send an e-mail to firstname.lastname@example.org.
Near Repeat Calculator
A software that originates with the relatively recent discovery of the near repeat phenomenon in burglary patterns.This communicability of risk to nearby locations for a short amount of time raises the possibility that other crime types may also suffer from a near repeat spatio-temporal pattern of behavior.
