Taxonomy of contemporary urban forms in France: Towards an Urban Atlas through Multiple Fabric Assessment
Résumé
Bridging southern and northern Europe, France presents very diversified urban landscapes, combining vernacular cores, modernist developments, sprawling suburbia and very specific exurbs. Traditional urban and rural landscapes were different among French cultural regions, whereas more recent ones are apparently more homogeneous throughout the country. Research in urban morphology and heritage conservation produced considerable knowledge of French traditional urban forms. On the contrary, attention to more recent forms and non-residential areas, as well as to their contribution to contemporary French cityscapes is more recent. The identification and characterization of France's urban fabrics and morphological regionalization of French cities remained for long a complex task, traditionally based on in-depth assessments, restricted to specific historical, geographical and cultural contexts. Recent advancements in morphometric analysis propose innovative computeraided protocols overcoming these limits. Among them, Multiple Fabric Assessment is a Bayesian streetscapebased urban morphometric protocol for morphological regionalization. First presented at ISUF2017, MFA has already been applied to several urban areas in different sociocultural contexts and geographical scales. MFA has been further developed and upscaled to analyse and compare wider study areas. The paper presents its implementation for four metropolitan areas of France, around the cities of Lyon,
