Context and motivations● From the institutional point of view:

● The CERMA lab. in the Ambiances Architecturales et Urbaines French CNRS unit,

● The Espaces et SOciétés French CNRS unit,● From the action-research point of view:

● Feedback from the (instrumental part of the) Ambioflux urbains interdisciplinary research project,

● Towards a systemic approach of the conception of pedestrian city tours…

● Implementation of a spatial formalism in a dedicated framework.

AmbiofluxIntents/Imprints - Marker/Attractor

● PIRVE's interdisciplinary research project,● Objectives:

● Ambients intents, execution plan (ambient markers),

● Ambients practical experience, spatial imprints (ambient attractors)

● Study the transformation process from markers to attractors (what's the trigger?),

● Geo-processing: spatial transcription of perceiving qualities.

Ambioflux – instrumental part● Simplifications:

● Visual- or soundscape perception → partial isovists or acoustic indices computations made by a visual/acoustic sensor/device;

● Pedestrian mobility → the mobile sensor move without real freedom degree, constant speed on the rails ;

● Urban environment → 2D building layer (BD Topo, from French national provider of reference geographic information, IGN) ;

● Impact of the visual- or soundscape → compare several fingerprints all along the pathway.

Ambioflux – soundscape approach

● Towards a new scattering indicator

Ambioflux – visualscape approach

● Partial isovists fields analysis (Benedikt 1979, Batty 2001, Meilinger 2009),

Ambioflux – visualscape approach

Perspectives - outlook● AmbUPAH project

● Toward a new prototype to assess urban patrimonial surroundings – implementation in the specific case of some pedestrian tours (in cities labeled VPAH) in the Pays de la Loire French region…
