This study explores incidents in a spatial and temporal context to achieve suitable strategies for
urban planning and policing in crime prevention/reduction. For this purpose, space and
time related incidents are analyzed through new crime ecology theories within the designed
loose-coupled GIS-based system at mezo-micro ecological levels in a case area within
Ankara Metropolis, in 2000. Its main argument is that incidents display differences in the
spatial and/or temporal distribution among planned, squatter, and in-transition settlements. In
exploring distribution of incidents at global and local scales, it also searches the validity and
critical adaptability of the new theories developed/practiced in North American and European
countries.
In line with new theories, incidents at global scale displayed clustering in space and time.
Generally, incidents in aggregate, concentrated mostly in planned / less in in-transition / least in
squatter areas / and particularly during spring-summer months. However, incidents against
people and against property predominated respectively in squatter and planned areas, and
between 18:00-00:00, and 00:00-08:00. As for local scale, incidents in aggregate, displayed
spatial interaction (clustering), but no space-time interaction. Spatial distribution in time
suggested that incidents persistently occur mainly in planned areas.
v
Incidents against property displayed highest level of spatial, and also temporal clustering at
global scale / and particularly spatial clustering (particularly for commercial burglaries/thefts)
and space-time clustering (for residential burglaries) at local scale. Complementarily, relatively
homogenous global scale spatial distribution of incidents against people is accompanied by
their non local scale spatial clustering or space-time clustering, whereby space-time dispersion
was observed for simple batteries.
