Accurate and timely traffic information enables road users to make informed decisions to enable them to optimise their route choices by avoiding congestion. Such information is instrumental to transport management as bus and taxi operators can reschedule their fleets in response to prevailing...

Space syntax is a technique for measuring the relative accessibility of different locations in a spatial system which has been loosely partitioned into convex spaces. These spaces are approximated by straight lines, called axial lines, and the topological graph associated with their intersection...

Many commentators have suggested that the 'natural surveillance' of public spaces can have important social consequences such as preventing or deterring crime. In this paper we introduce a model of natural surveillance in public space which uses visibility graph analysis. The model is applied to...

This paper contributes to the demonstration that the self-similar city hierarchies with cascade structure can be modeled with a pair of scaling laws reflecting the recursive process of urban systems. First we transform the Beckmann's model on city hierarchies and generalize Davis's 2^<i>n</i>-rule to an...

Today, geographic information technologies (GITs) stand out as the unavoidable answers to the French local governments' new stakes. Yet, an important discrepancy has been noticed between the utility levels (in the qualitative sense) and the theoretical intrinsic potential of these technologies....

The Internet and the World Wide Web offer a new solution to the problem of sharing scientific knowledge. Unlike traditional libraries based on print media, these new technologies facilitate the sharing of any information that can be expressed in a binary alphabet. Environmental models expressed...

This paper outlines a method for using the mathematics of fuzzy sets that is well suited to measure and characterize periurbanizing (<i>desakota</i>) systems typical of China, Southeast Asia, and other areas experiencing rapid urbanization. Drawing on Kosko's 'fuzzy hypercube', we derive three distinct...

Research on neighborhoods is dominated by a focus on the social aspects of neighborhood life. The ability of neighborhoods to function as service providers is a critical and understudied aspect of neighborhood research. This paper offers a methodological contribution of the analysis of...

This paper reports on a primary metric tool developed in a collaboration between an architecture researcher and a computer science researcher. The development of this tool emerged from the concept that the spatial openness (SO) -- the volume of free space measured from all possible observation...

In the wake of proposals in the 2002 Planning and Compulsory Purchase Bill to replace the current system of development plans with a new generation of planning policy tools, this is an appropriate moment to reconsider the role of design policies within English planning practice. As the era of...
