The Risk Terrain Modeling Diagnostics (RTMDx) Utility is a software application for Risk Terrain Modeling (RTM) and for diagnosing spatial crime vulnerabilities. It helps to identify and communicate environmental attractors of illegal behavior and crime incidents. Information products can be used to anticipate places that will be most suitable for criminal activities, identify where new crime incidents will emerge and/or cluster, develop place-based interventions, strategically and tactically allocate resources, and prioritize efforts to mitigate crime risks.
RTMDx automates most steps of risk terrain modeling. The algorithm empirically tests a variety of spatial influences and analysis increments for every risk factor input to identify the most empirically- and theoretically-grounded spatial associations with known crime incident locations. Then, it selects only the most appropriate risk factors (with their spatial influences optimally operationalized) to produce a “Best” Risk Terrain Model. The final model articulates the vulnerability for crime with relative risk values at every place throughout the study area. The environmental factors that create specific vulnerabilities at places are listed and weighted according to their relative spatial influence on the outcome event. This aids in the prioritization of risk mitigation efforts.
Runs on PC or Intel-based Mac with Boot Camp. It is a Microsoft Windows application.
