Excessive CO₂ emission and its effects on global warming has become a primary issue of urban and regional planning. Cities’ space-uses and intra-urban traffic are the main contributors to global warming. Space-uses as well as traffic patterns are processes exhibiting characteristic dynamic properties. Focusing on sustainability issues in planning thus means to deal with cities as processes rather than just spatial structures. The problem of representing cities as processes lies in the complexity added by introducing the dimension of time. It is hopeless to model cities in terms of, e.g. time geography (Hägerstrand, 1970). We thus propose a more pragmatic approach, an approach that combines a bottom-up representation of a characteristic overall topological feature of urban space with a top-down representation of an overall dynamical feature that the city, when looked at as a process, exhibits. The overall topological feature of urban space results from describing cities as facilities made for reasons of the exploitation of the advantages of close proximity to a large number of other people. The overall dynamical feature of the city conceived as a process relies on the dynamical stability of the activity patterns that space-uses characteristically consist of. By thus combining topology with dynamics we show the possibility of modelling the city as a process with the standard data available.
