A new modelling paradigm for sketch-planning applications in transport and urban policymaking is presented. It is based on the use of a scenario-forecasting procedure which employs genetic algorithms to develop a set of alternative scenarios for accomplishing a set of predetermined goals. The...

The derivations of four Taiwanese traditional vernacular houses, based on a shape grammar, are illustrated. We also discuss the role of grammars in describing design style, using the Taiwanese houses as exemplars.

In this research we address factors contributing to landscape change in a midwestern (USA) watershed. Specifically, the relationship between the parcelization of agricultural land (ownership subdivisions) and changes in amounts of riparian forest cover are explored. The study area is the River...

There is an increasing contemporary interest, particularly in Europe, in the spatial organization of urban regions and in spatial strategy. But there is a general loss of confidence in political systems as mechanisms for conflict mediation and the strategic management of collective affairs. This...

In this paper the possibility of using cellular automata (CA) to build and test urban development models is explored. The AUGH project, which aims to construct a generic software environment for building urban automata, is also described. After careful evaluation it is concluded that CA, and...

In policy analysis, the concept of framing has become an idea of good currency. In planning, framing means giving shape, not only in a figurative but also in a literal sense of the word. So, drawn images are used to support verbal statements of policy, or they directly express policies. In this...

Identities of the form <I>A </I>- <I>A </I>restructure shapes without changing them in any way.

The management of National Forests is a complex problem in which resources are scarce and multiple uses often conflict. A key aspect of forest policy is the determination of how to manage the <I>timber </I>resources of the forest, as many of the nontimber resources are conditioned by timber levels and...</i>

Let us assume that there exists a certain activity that requires a fixed shape and size of space, and is so crucial for lots with detached houses that the value of such a lot is largely affected by whether or not it contains that space. If the hypothesis above (designated as the 'critical shape...
