Strategy: Hot spots, increased patrol, zero tolerance, problem-oriented policing (varied by beat)

Matrix Dimensions:
X-axis: Communities/neighborhoods
Y-axis: General
Z-axis: Proactive

Results: Statistically significant success
Aggregated beats showed decrease in Part I crimes; hot spots and zero tolerance beats do better than POP and increased visibility beats

Methodological Rigor: Moderate/rigorous- comparison to other beats in the city

Abstract: This study evaluated the Targeted Beat Program, a crime reduction program initiated by the Houston, TX, Police Department, 1994-96. Data were collected through a process evaluation and an impact evaluation, U.S. Census statistics, and 285 hours of observation data. The program funded officers' overtime work in the 7 highest crime beats in four substations in the city. Four approaches were employed: high visibility; hot spots targeting; zero tolerance; and a problem-oriented method. Increased police presence led to significant reductions in crime. Officers on the targeted beats were positive about the program, though some officers could have been more productive while on targeted patrol. Crime statistics indicate no geographic displacement of criminal activity because of increased police presence. Though more could have been accomplished with greater planning and coordination, additional resources devoted to crime interdiction effectively reduce crime.
