Public Perceptions Of Crime Maps: Considering The Impact Of Map Style On Perceptions Of Safety, Kathryn Wuschke, Kris Henning, Greg Stewart, Kaitlyn Bonn

Criminology and Criminal Justice Faculty Publications and Presentations

Presentation slides for a study that questions how people may interpret and understand the types of crime maps that are frequently publicly available. As public crime maps increase in use and distribution, researchers are beginning to explore the impacts of access.

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

Criminology and Criminal Justice Faculty Publications and Presentations

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 …

Trends In Crime Measures: British Columbia, 1999-2013, Paul J. Brantingham, Kathryn Wuschke, Silas Melo

Criminology and Criminal Justice Faculty Publications and Presentations

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 …

Cartograms, Crime And Location Quotients, Martin A. Andresen, Kathryn Wuschke, J. Bryan Kinney, Patricia Brantingham, Paul J. Brantingham

Criminology and Criminal Justice Faculty Publications and Presentations

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 …

Land Use Based Crime Rates: Exploring Patterns Of Land Use And Crime Rates In Coquitlam And Port Coquitlam, Kathryn Wuschke

Criminology and Criminal Justice Faculty Publications and Presentations

While it is certainly valuable to understand the counts of specific crime types by location, in order to contextualize the relationships between these features, rates are needed. Table 1 further explores this relationship by calculating the rate of each crime by land use. While rates are often employed using population as a denominator, such a measure is not practical when exploring crime at the parcel level. In this case, rates have been calculated according to crimes per 100 lots, producing an understandable and comparable value across all categories of land use and crime.

Land Use & Crime: Coquitlam/Port Coquitlam: Exploring How Violent, Property, Mischief And Drug Offences Relate To Land Uses, Kathryn Wuschke

Criminology and Criminal Justice Faculty Publications and Presentations

Coquitlam and Port Coquitlam are two suburban cities that are currently undergoing rapid physical changes. In order to accommodate growing urban populations both within these locations, and in the wider surrounding region, Coquitlam Centre area has been designated as a Regional City Centre. It is intended to act as a downtown core for the neighbouring municipalities, and as such, is experiencing rapid redevelopment, focusing on mixed land uses and dense residential/commercial mixes. In an effort to understand and model the shifts in crime types and densities that may be associated with this redevelopment, ICURS has begun exploration of the relationship …

Major Arteries And Motor Vehicle Theft: Investigating The Spatial Distribution Of Mvt In The Lower Mainland District, Kathryn Wuschke

Criminology and Criminal Justice Faculty Publications and Presentations

Vehicle theft, like most crime types, is spatially concentrated, with more than one quarter of these crimes occurring within fifty meters of a major roadway. Spatial analysis and mapping of all motor vehicle thefts (MVT) occurring in the PIRS system for the Lower Mainland District in 2004 and 2005 emphasize clear clustering around major roads. This map also reveals hotspots of MVT intensity occurring in specific point locations across the landscape. Future fact sheets will analyze these activity nodes to determine the specific land uses around which MVT events tend to cluster.
