Risk Terrain Modeling, or RTM, is an approach to spatial risk analysis that was invented by Les Kennedy and Joel Caplan at Rutgers University and has been developed in collaboration with Eric Piza. It is used to identify risks that come from features of a landscape and model how they co-locate to create unique behavior settings for crime. We say crime as the outcome event because that was RTM’s inaugural application. But, it is currently used for a variety of other topics, including injury prevention, public health, epidemiology, traffic/transportation planning, border security, pollution, or maritime piracy. RTM is by all intents-and-purposes a diagnostic method. With a diagnosis of the attractors of criminal behavior or other hazardous outcomes, you can make very accurate forecasts. RTM offers a statistically valid way to articulate vulnerable areas at the micro-level. Read more about RTM here.
