RBSim (Recreation Behaviour Simulator) Model

An often quoted model integrating GIS and Agent-based modelling is that by Randy Gimblett et al. Their agent-based model, RBSim used real-world geographic features (including topography, vegetation and roads) to evaluate the recreational use of Broken Arrow Canyon, Arizona. Specifically, current hiking, bike, and off-road trail paths were mapped in a GIS as a series of raster layers and potential alternatives simulated in order to aid management decisions of environmental protection and enhance recreational user experiences of the canyon.

The model itself is quite simple but highlights how geographic data can be integregated into an agent-based model. Additionally how agent-based modelling can be used as a tool to 'think with' by allowing the user to alter the setup model parameters (eg the number of hikers).
