Criminal Geographic Target Model Optimal Integrated Distance between Spatial Points of Serial Burglaries
Abstract: We used criminal geographic targeting (CGT) model—one of the geographic profiling methods— based on the real data of serial burglaries of two Chinese cities Q and S to discover the journey- to-crime distance of offenders and the optimal integrated distance between points for CGT model. We wanted to detect offenders’ residences and serve for the police department. Our results show that 1) the serial burglary offenders of our two research areas comply with the distance-decay function when they commit crimes, that is, they always repeatedly commit crimes within a certain distance; 2) the empirical constants of CGT model in the two research areas exhibit consistency; 3) compare with the traditional CGT model, city Q uses standard distance of crime points to simulate the “buffer zone” of offenders can improve the accuracy of CGT model.
