Detecting Emerging Space-Time Crime Patterns by Prospective STSS
Detecting crime patterns as they emerge in both space and time can enhance situational awareness amongst security agents and prevent epidemics of crimes in potential problematic areas (Neill and Gorr, 2007). Amongst others, space-time scan statistics (STSS) (Kulldorff et al. 2005) and space -time kernel (Nakaya and Yano, 2010) have been widely used in crime analysis. Stemmed on strong statistic...
متن کاملLearning to rank spatio-temporal event hotspots
Crime, traffic accidents, terrorist attacks, and other space-time random events are unevenly distributed in space and time. In the case of crime, predictive policing algorithms aim to focus limited resources at the highest risk crime hotspots in a city. A crucial step in the implementation of these strategies is the construction of scoring models used to rank spatial hotspots. While these metho...
متن کاملAnalysis of residential complexes with the approach of space syntax in terms of mass crime (Case Study: Shiraz Residential complexes)
Various factors affect the degree of mass crime of an environment, including social, economic, and physical factors. The purpose of this research is to investigate the role of the physical components of an environment on mass crime rate. In this regard, open spaces between residential complexes were selected as the case studies and based on five outdoor patterns including linear pattern, disper...
متن کاملHotspot Formation and Dynamics for a Continuum Model of Urban Crime
The existence, stability, and dynamics of localized patterns of criminal activity are studied for the reaction-diffusion model of urban crime introduced by Short et. al. [Math. Models. Meth. Appl. Sci., 18, Suppl. (2008), pp. 1249–1267]. In the singularly perturbed limit of small diffusivity ratio, this model admits hotspot patterns, where criminal activity of high amplitude is localized within...
متن کاملCrime Hotspot Detection: A Computational Perspective
Given a set of crime locations, a statistically significant crime hotspot is an area where the concentration of crimes inside is significantly higher than outside. The motivation of crime hotspot detection is twofold: detecting crime hotspots to focus the deployment of police enforcement and predicting the potential residence of a serial criminal. Crime hotspot detection is computationally chal...
