SUMMARY:

This research investigates how much sparse distribution of  locations is an effect of potential movement provided by the road configuration covering the entire set of these locations. The observed area comprises a road network that borders part of the coast of Paraíba and Rio Grande do Norte, connecting at least 160 locations scattered across the surface of 25 municipalities from João Pessoa-PB to Natal-RN between the sea and a federal highway that runs through these two capitals. The objective is to detect patterns of urban dispersion in a network of multiple cities and small towns by fraying the notion of cities as movement economies. The thesis is that the potential flow (people, objects, information) generated by fixures (fixed assets, buildings, infrastructure, equipment) helps to understand the fixing process itself and that the movement also structures the peri-urban, interstitial, less built-up space. The principle of cities as movement economies  proposed by Bill Hillier (1996) has remained valid in a representative contribution of studies of intra-urban centrality. This principle is affiliated with the theory of the Social Logic of Space (HILLIER & HANSON, 1984), whose axiom is that, as society is inseparable from space, spatial patterns reveal social patterns;  its instrument is Space Syntax Analysis. Cities as movement economies  accompanied the discussion about the process of generating places in the city (cities make the place), matured with the idea that urban conformation is doubly structured by long-range and short-range movements. The question of how to deal with range patterns that exceed the peri-urban limit was deepened by Kimon Krenz (2018) when proposing regional morphology, a mix of Space Syntax with Christaller's Theory of Central Places (1933, 1966), this based on a static arrangement of attractors. The present work departs from regional morphology, placing more emphasis on the potential cost of travel, strongly affected by components of randomness, whose field of possibilities is understandable by analyzing the configuration despite the static attractiveness of the centers. The expression fixures and flows is borrowed from Milton Santos, this time with fixures denoting the configuration and flow, its effects. In due course, Milton Santos revised the Theory of Central Places, describing two circuits of static influence between cities, a duality that, throughout the present study, demonstrated congruent with the dual generative structure proposed by Hillier. The method consists of comparing topological accessibility maps considering angles in changes of direction (HILLIER, 2012) with maps of locations and densely built areas; coincidences and disparities between layout, occupation size and accessibility are investigated in the search for patterns combining building density/dispersion and movement. A long and a medium range radius were chosen to prospect structures concentrating potential movement. The result is that, in the network of sparse locations observed, some beach locations relatively far from the capitals, coincidentally tourist and summer resorts in remnants of old colonial settlements in bays, coves and river bars, are nestled in a highly accessible centrality structure positioning beaches and capitals at the same hierarchical level of propensity to pass routes, even with part of these passing through extensive interstices characterized by rarefied building occupation — the conformation is that of a comb, whose back is the federal highway parallel to the sea and the teeth are the perpendicular accesses to the coast. At the same time, the intra-urban core of small localities is lined with another structure of centrality and movement, relating to intermediate routes, which can exceed the size of the locality but without covering the entire system. The double structure comes up against traces of the legacy of capillary paths from the sea and river branches, interspersed by extensive centuries-old sugar cane fields, where shortcuts from the capital-beach comb of access recurrently bypass most of the small towns, including riverside ones and indigenous people. The conclusion is that, given that the apparent attractiveness of the beach, peripheral to the capitals, is supported by potentially lower travel costs, a kind of economy of movement reveals subtleties in the arrangement of small locations that are not so accessible, or are more laborious, by attractiveness biases generally based on the accumulation of goods and services, at least in the case studied. The notion that the arrangement of scattered locations together is guided by movement opens up perspectives for the refinement, at the level of street sections and mobility circuits, of studies on peri-urban occupation and urban networks on a regional scale.
