Abstract
This paper explores analytical tools designed to describe urban form–space structure at a global level, eventually in quantitative mode, by a configurational approach based on the space syntax theory. The sample consists of 44 Brazilian cities, selected by demographic and cultural heritage criteria. Brazilian city configuration is contrasted with that of another 120 cities worldwide, comprising a total sample of 164 urban settlements. Analysing topological and geometrical aspects, this paper aims at revealing attributes emerging from relations among parts in a system. Urbanistic features are investigated in an endeavour to understand how different layouts can be classified into specific spatial types. The city is evaluated according to its hierarchical structure, measured mainly in terms of its topological accessibility. The approach is underpinned by the theoretical, methodological and technical apparatus of space syntax theory, employing axial map representation and its attributes. GIS tools are used to organise the database. The paper seeks to answer a question – is there a typical Brazilian city, contrasting with a world panorama? – that is limited in scope by the exploratory nature and the specific approach of the research. Four types of variables are considered, related to (1) form and distribution; (2) density and compactness; (3) topology; and (4) zoning/centralities. Three expressions summarise the findings and convey the idea of a typical Brazilian city – fragmentary space, patchwork and oasis in the labyrinth.
