| Abstract: | We explore the simulation of urban growth using complex systems theory and cellular automata (CA). The SLEUTH urban CA model was applied to two different metropolitan areas in Portugal, with the purposes of allowing a comparative analysis, of using the past to understand the dynamics of the regions under study, and of learning how to adapt the model to local characteristics in the simulation of future scenarios. Analysis of the two case studies show the importance of SLEUTH's self-modification rules in creating emergent urban forms. This behavior can help build an understanding of urban social systems through this class of CA. |
