400 members
, as well as developing customis
ed GIS applications


together these
have enabled crime mapping to become a standard within Victoria Police’s
analytical processes a
nd systems.

ABSTRACT


Application of predictive mapping techniques for

guiding

targeted

resource deployment.


In an effort to reduce burglary rates
in Victoria Police’s North West Metro region
, sign
ificant resources
were provided by

both

the State Policing Office

and State intelligence Division

to target problem areas
and de
tect/deter burglary offences.

Consideration of the

deployment of these resources was essential to
ensure they were in the right place, at the right time.


Whilst traditional ‘hotspot’ techniques look at where crime has occurred

(retrospective), it was iden
tified
that police
really
needed to know where the burglaries were likely to occur (prospective). Several
predictive methodologies (including repeat, near
-
repeat, and the Gi* spatial statistic) were researched,
tested and combined to create a system for pr
edicting the

most

likely locations for upcoming burglary
events. Statistically
-
robust
temporal analysis also provided an optimised deployment timeframe, so that
the police had the best chance to deter burglary events and apprehend offenders.


The output of

this process was a

weekly

series of maps which clearly indicated the locations, days and
times for optimal deployment of police members. These maps were used

directly

by
Police Command to
plan

operations, and became an integral
tool for
decision making du
ring Victoria Police’s efforts to
reducing burglary rates in the region.
