The document summarizes an urban growth simulation model built using cellular automata. It allows users to design road networks which drive urban expansion as built and unbuilt cells interact according to programmed rules. The model simulates self-organized growth of urban fabric and the growth rate decreases as available space becomes saturated. Instructions are provided to open the Netlogo model file and run simulations by drawing roads. A second model called Cities CORE is also summarized, which simulates comprehensive city creation through automatic landscape generation and user-directed development.
