In particular, directed patrol had a stronger effect for residential burglary micro-time hot spots and showed that one additional directed patrol per day is expected to result in 36%% less subsequent residential burglaries and 16%% less residential theft from vehicle crime.
In terms of response to the micro-time hot spots, the agency mandated a minimum of 14 days of directed patrol after the bulletin was disseminated to officers.
There is a wide range of research on directed patrol in long-term hot spots (Braga et al. 2014), but there is much less research on response dosage (Groff et al. 2015; Telep et al. 2014).
Thus, it appears as though short-term responses, particularly directed patrol, that have a short-term effect in long-term hot spots might be better suited for "crime flare ups".
Officers recorded their directed patrol activities in an Intranet database while on shift.
The findings were stronger for residential burglary, and a visual examination of first standard deviation confident intervals of directed patrol rate by crime suggests that between four and six directed patrols per day in residential burglary micro-time hot spots was optimal.
The exception is the relationship between subsequent crime and directed patrol rate for residential burglary which resulted in a strong significant correlation of −0.77.
