Crime In The Built Urban Environment: Exploring The Impact Of Road Networks And Land Use On Residential Burglary Patterns, Kathryn Wuschke, Justin Song, Valerie Spicer

For decades, environmental criminology theory has emphasized the connections between the built urban environment and criminal activity. The urban landscape determines both the origins and destinations of everyday journeys from home to work, school, shoppingor entertainment areas, and it provides the pathways on which residents travel. As such, the built environment guides and limits the locations that offenders may search within in order to identify potential criminal opportunities. For these reasons, access and proximity to major roads, as well as key local activity nodes such as shopping malls, transit stations and schools, have been frequently found to be an important …

Three different measures of crime intensity are available in British Columbia: the Standard Crime Rate (SCR) which measures the number of crimes per 100,000 population; the Crime Severity Index (CSI) which measures the weighted risk to residents of a police jurisdiction; and the Crime Gravity Score (CGS) which measures the seriousness of the set of crimes handled by police in a particular jurisdiction.

All three measures show declines over the past decade. British Columbians are safer now than they were in the early 2000’s. Police resource implications of the measures are different. The SCR and CSI have both declined by …

Visualizing spatial information has a long history in the field of cartography. Though there are generally accepted forms of spatial data visualization to represent different types of spatial data, the interpretation of the resulting maps tends to be subjective at best and incorrect, at worst. Cartograms are an increasingly popular form of spatial data visualization, recently applied in political and epidemiological analyses in an attempt to better represent the spatial data under analysis. We use the cartogram procedure to map crime rates and location quotients. Using this visualization approach, we are able to show the usefulness of cartograms to represent …
