The special sessions of the Annual Meeting of the Association of American Geographers in 1994 marked the development of the paradigm of highly disaggregated CA modelling, which is very different from "traditional" land use and transport modelling. The sessions subsequently resulted in a special issue in Environment and Planning B (Batty et al., 1997). Advances in GIS visualization and data processing capacities have further added momentum to CA applications. Since then, there have been widespread applications of various sorts of CA.
