Cellular Automaton – CA Applied Urban Developpment In the case of urban modelisation, the cell space on which a cellular automaton operates might be considered equivalent in an urban sense to an environment, a landscape, or a territory. The standard resolutions is 500×500 m2 up to 25×25 m2. It’s the grid of the city. Neighborhood : the traditional implementations of the concept are bases on Von Neumann or Moore neighborhoods. The main relationship between 2 automatons : •Attraction (urban/ecological) •Repulsion (urban/industrial) Neighborhood effect defined as a measure of the interaction between land uses at two locations that decreases linearly until zero with the distance between them. Normalized measure are : • 1 if there is total attraction; Final real Land Use Map • 0 if there is no relationship; • -1 if there is total repulsion Example of simulation Initial Land Use Map
