Various complementary approaches are mobilised to better understand urban structures and the mobility practices associated with them:

Advanced surveys: introduction of new survey and interview methods through a multidisciplinary approach involving geographers, psychologists and linguists. These methods can be used to explore what respondents feel while using approaches that allow the results to be integrated into behavioural modelling.

Fractal analyses: development and validation of fractal analysis methods adapted for exploring the spatial organisation of urban structures and their value for developing new urban spaces.

One of the research priorities for several years has been to better describe and understand the spatial organisation of urban fabrics and transport networks based on a multi-scale approach using fractal geometry. The work done relates to methodological aspects (exploration and development of measuring methods and indicators) and the distinction and classification of built fabrics depending on their morphological characteristics and the relationship between the road network and the distribution of the built environment. This has made it possible to identify the influence of historical contexts and development strategies as well as certain properties common to European cities.

Three different types of fractal form







Systemic analysis: allowance for the complexity of interactions among urban forms, daily and residential mobility, decision-making processes of individuals and households and decision-maker strategies in an integrated approach.
