Risk Terrain Modeling - Residential Burglaries
Much like a contour map, Risk Terrain Modeling (RTM) assigns a level of risk to real-world locations and stretches them over a contiguous geography. Using a geographic information system (GIS), a rasterized map of an area is created where each cell in the raster is assigned a value based on multiple risk variables. Risk variables can be distance from a location, proximity to related events, socio-economic factors, temporal/seasonal factors, and/or land use. With regards to crime analysis, these risk variables can differ, as well as have more or less importance to the investigated crime. The common risk correlates, criminogenic factors, associated with residential burglary are; frequency of past residential burglaries, measures of social disorganization, proximity to pawn shops, proximity to public transportation, land use type (residential). The resulting raster will help guide law enforcement personnel to more focused and efficient patrolling.
