A recent initiative for the Elk Grove Village Geographic Information
System (GIS) has been the creation of police beat and sub beat
information including coordination with the Northwest Central Dispatch
Center who manages the Village’s emergency calls.
A desire of the Elk Grove Village Police Department is to better
understand the dynamics of workload throughout the village and if
certain areas could benefit from increased or an adjustment of patrol
units. To realize the demand of the beats and sub beats the GIS was used
to calculate statistics for 2008 and 2009 calls for service.
Summarizing statistics by beat which as of now are generally defined by
certain zoning types allows for an understanding of overall police
activity. Further analysis by time of day showed which shifts are the
busiest as well.
This information will provide a decision support tool as a
restructure of beats is considered and can begin without interruption to
dispatch services by testing dispatch changes along existing beat
boundaries. Additional investigation of the data may suggest that
patterns exist at even smaller time ranges which would suggest a shift
of patrol at certain times of day or that certain types of incidents
occur more often in some areas and result in a longer period of time at
those types of calls.
After making use of these types of analysis it will be determined
which are the most influential factors to determine patrol needs and can
continue to be performed over time to validate trends and truly
understand the policing demands.
