Basic Analysis of the relationship between precursor events of sex crimes and urban spatial characteristics

Abstract

Although there are several researches having tried to reveal environmental factors which have something to do with precursor events of sex crimes, there is no research considering possibilities that the degree of effects which some factors have may depend on characteristics of districts and that structure of road network may be relevant with occurrence of such events, both of which have already been pointed out in some researches regarding other crimes. In this research, we analyzed the effect of a variety of factors on precursor events which have occurred in the past three years by using multilevel model to detect factors that have an effect through all districts. In addition, using a method called Urban Network Analysis, we found an effect of street network structure on precursor events.
