“…Pereira Bezerra de Melo Junior and Canuto da Silva [51] used a similar approach to examine the isovist properties of locations that experienced thefts and robberies in a neighborhood in Recife, Brasil. Results of the correlational analysis showed that crimes occurred in areas with low occlusivity values, lower isovist area, lower isovist perimeter, and low visual integration.…”

Purpose: Assessing a level of surveillability, supervision, and expected guardianship in residential neighborhoods has been a topic of interest since the early work of Jacobs’ ‘eyes on the street’, and Newman’s ‘defensible space’. This paper reports on the use of isovists (two-dimensional polygons that represent the characteristics of the visual field) in understanding incidents of ‘breaking and entering’ in Ypsilanti, Michigan. Approach: Two measures relevant to environmental criminology were assessed: accessibility and surveillability. Findings: The findings indicate associations between incidents of crime and measures of visual accessibility. However, the level of homeownership was found to interact with the predictive models, suggesting the possible effect of ‘guardianship’. The geometrical shape of the isovist may also indicate where along a particular route, a crime is more likely to be committed. Originality: The results have the potential to assist law enforcement in identifying ‘hotspots’, and city planners in understanding the implications of urban design on crime.
