Travel-To-Crime: Homing In On The Victim

ABSTRACT

Environmental criminology focuses on the intersection in time and place of the offender and victim. Patterns of crime are generally explained in terms of the routine activities of the offender. His or her travel to crime distances are short and crimes are committed within the offender's 'awareness space'. It has generally been theorised that victims also have short journeys to crime, associated with their routine behaviour. This review, however, suggests that occupancy of 'unawareness space', where people are away from familiar surroundings, may confer heightened risk. This is supported in research in the special case of crime and tourism, though other travelling victim patterns have been largely ignored. This paper postulates that crime risk increases at the intersection of offender awareness and victim unawareness spaces. The 2002–3 British Crime Survey provides some suggestive evidence on this. Its analysis reveals that 26.9% of self-reported victimisation occurs more than 15 minutes away from the victim's home. For personal

Modeling Criminal Distance Decay

Criminal distance decay is the fundamental notion that a relationship exists between the distance from an offender’s home base to a potential target location and the likelihood that the offender chooses to offend in that location. This relationship is important both for its operational effect on police agencies and on models for offender behavior. A number of factors influence the distance decay function of an offender, including the local geography and the offender’s decision making process.This article addresses a study of the interactions between the two-dimensional offense distribution that describes how offenders select targets and the corresponding one-dimensional distance decay function. It also present the calculation of the coefficient of variation for 324 residential burglary series in Baltimore County, Maryland. These data do not support the notion that the distance decay behavior of an individual offender is governed by a number of common choices for distance decay, including the negative ...
