Calibrating and validating cellular
automata models of urbanization
Paul M. Torrens
Automata-based modeling of urban dynamics is an active research enterprise that has gathered momentum at an
increasing pace. Despite its popularity, research and development in this domain remains in a state of relative
stasis, largely constrained by persistent problems in registering simulation scenarios to the real world that model
developers seek to simulate. To a degree, these problems are indicative of modeling as a scientific endeavor more
broadly, but application of automata models to human-environment contexts raises some particularly challenging
issues for calibration and validation that the field could benefit from addressing. This chapter reviews the state of
the art in applying cellular automata models to human-environment interactions in complex, messy, dynamic
urban systems, with all of its associated problems and promise.
