In this paper the growth management system in Montgomery County, Maryland, is reviewed and critiqued with the intent of finding generalizable lessons. An overview of the twenty-year-old system is followed by an analysis of its consequences and implications. The system fails to provide effective...

As our environment consists not only of space but also of time, there is cause to develop spatiotemporal planning: the planning of spacetime. To devise and implement spatiotemporal plans practicable methods are needed for obtaining knowledge about behaviour in space and time. In this paper we...

This paper extends the debate over the ideal of the sustainable city, particularly as it relates to transport, by providing empirical evidence, from five case-study cities in the United Kingdom and one in the Netherlands on the links between urban form and energy consumption in transport. It...

Integration with geographic information systems (GIS) has helped move cellular automata (CA)-based urban and regional models from the realm of instructive metaphors to that of potentially useful qualitative forecasting tools. Such models can now be fully interactive for exploratory purposes and...

In this paper the possibilities of using tradeable permits in the regulation of road transport externalities are explored. After discussing the theory of tradeable permits and some practical applications, we will identify a number of potentially promising applications of their usage for coping...

Evaluation and implementation studies have a well-established tradition For evaluation in general, this tradition seems to offer a clear-cut research design. This is not true for evaluation of strategic plans. First, most evaluation and implementation research deals with specific and...

In this paper I will report on the capability of cellular automata (CA) to simulate urban structure and development. The model is based on CA and economic theory, structure and policy parameters, and four actors -- white-collar and blue-collar populations, and service and base activities....

The model presented in this paper is an attempt to reexamine spatial dynamics in the light of new concepts and techniques. Among these, cellular automata and parallel processing should contribute to revitalize dynamical studies in the geographical space and deserve consideration. A complete...

The use of fractal techniques to model aspects of urban form is now well established. However, to date these have concentrated on specific general attributes of urban form, usually focused at a macro level. In this paper we argue that the urban system is complex and its global spatial attributes...

Many problems require the identification of a subset of points to minimize (or maximize) some function. A vertex substitution heuristic (VSH) employs a strategy of one-by-one replacement to approximate, or perhaps find, the optimal set. The Teitz and Bart heuristic is the archetype of this...
