Towards a Spatial Semantics to Analyze the Visual Dynamics of the Pedestrian Mobility in the Urban Fabric

چکیده
The aim of this paper is to evaluate the impact of visual ambiences (visualscape) onto an urban pedestrian pathway. This work takes place within the interdisciplinary research project called Ambioflux, dealing with the sustainable mobility issues in the city. We add to the spatial semantic layer GDMS (Generic Datasource Management System) an innovative method based on partial isovists fields in order to compute the visibility of the pedestrian all along his pathway. This method allows “concatenating” several partial visibility polygons in order to represents the visual perception of the pedestrian. After a brief overview of the visibility analysis context, we justify the need of a specific semantic tool to develop the type of dynamics visual analysis we focus on. The remainder of this paper is dedicated to the methodology of the mobile pedestrian pathway’s visual fingerprint characterization using the spatial formalism already described. At last, we present a use case based on a real city tour so as to identify the best rotation’s direction from the visual perception point of view. 2 Thomas Leduc, Francis Miguet, Vincent Tourre, Philippe Woloszyn

متن کاملTowards a Landscape Potential. a Method Based on a Systematic Characterization of the Surrounding Urban Fabric through the Visual Dynamics of Pedestrians
The pedestrian mobility is a way to understand how a person might experience the void in between the buildings (this void defines a space portion as a shape) and therefore the urban fabric itself. The present paper aims to characterize landscape potentialities through pedestrian perception. Our proposal consists in building a set of sort of sensory Digital Elevation Models in which the third di...
متن کاملMeasuring surrounding space to assess the pedestrian visual aperture angle in the urban fabric: towards a Kurtosis based isovist indicator
Partial isovists fields are useful methods to analyze the urban morphology taking into account the visual perception of the pedestrian. However, as previous studies involve a constant visual aperture angle all along the pathway, this paper presents an adaptative method of aperture angular variation according to urban morphology properties. Aperture angle increasing, nearby a square or at roads ...

The rural centers integrations in the city which in some countries have been named as “urban villages” are the consequence of rapid urbanization and accelerated growth of our city. Since the rural centers integration in the city has been often without any plan, it has had various consequences on the environmental, physical, economical and social aspects. The present study has paid attention to ...
