That patrolling the most chronic hotspot on the London bus network for 15 minutes at a time will reduce crime.
The trial sites were identified using community safety Driver Incident Reports. These are calls made by bus drivers to CentreComm, the London Buses control room, who determine whether an emergency response is required. Incidents may include criminal damage to the bus, passengers refusing to pay, threatening violence etc. Data supplied by iBus allows incidents to be closely matched to the nearest appropriate bus stop. Trial sites were tested for spatial autocorrelation and temporal stability. Crime and CAD data supplied by the Metropolitan Police will be the primary outcome measures for the trial.
Approx 50 hotspots.
Fully randomised control trial
Proactive patrol by a pair of officers (one PC, one PCSO) in the hotspot for 15 minutes. Hotspots to receive at least three treatments a day for three months.
The Metropolitan Police Service recorded crime and bus driver incident reports.
Hotspots policing at bus stops - and potentially other “micro places” - has a limited deterrent effect if patrol patterns are predictable. Police agencies therefore need to randomise their deployments both spatially and temporally to increase the unpredictability of enforcement.
