Mobility, cities and transport / Anticipation of new practices and new urban spaces

Based on modelling, simulation and evaluation, this research area seeks to identify and anticipate conceptual approaches and levers for action for the sustainable development of new urban spaces:

e-Cities: analysis of the impacts of new technologies on mobility practices and urban shape

Since the 1990s growth in equipment and use of the Internet and mobile phones has been phenomenal. This mass appropriation of ICTs accompanies and accelerates changes in life style. It impacts our relations with territory and with mobility, work and business organisation, consumption and health and leisure practices. One can, however, question the (ecological) risk of investing in these new practices and the benefits we derive from them in terms of well-being and quality of life. Examples of on-going or completed studies:

EFFETS: (Experimenting, training for distance working, estimating flows averted, effects on mobility and levels of greenhouse gas emissions)

image preditThe EFFETS project is designed to test and simulate the impacts of working from home on the active population and their mobility practices. It shows that not only does working from home affect travel (modes, forms and reasons) but it also acts on the programme of activities and the organisation of all individuals in the household. For example, working from home promotes hypermarket visits outside of Saturday morning peak times, freeing up this time slot for individual and family cultural or sports activities so generating new demand and new types of travel that need to be identified. In the longer term it will also affect residential choice.






 e-commerce, click and collect, and home delivery

E-commerce leads users to adopt 'multichannel behaviour', combining several channels in the purchasing process. The findings of preliminary studies reveal that regular e-commerce users do not stop visiting shops and physical points of contact (no substitution effect). There is hybrid frequentation of both channels, impacting socio-spatial practices. Moreover, the expansion of home deliveries and the advent of virtual hypermarkets (click and collect), as with distance working, are changing our relationships with territory in terms of usage.

Over-the-phone medication prescription

Poster AGF-CNFG 2012-ARM-01 While there is much talk of the value of distance consultations in remote areas, the results of this study show that 'phone prescriptions' from emergency call regulating centres are made more, proportionally, for calls from urban settings. The increase in 'phone prescriptions' clearly reflects the establishment of a new use for the telephone in cities to reassure patients and that meets the need for immediate medical advice. This changes our relations with health services and their location. The distribution of health services and above all their physical and/or virtual accessibility appear to be decisive factors for dynamics of new urban spaces.




New fractal cities: mobilisation of fractal geometry for designing multi-scale urban development scenarios and multimodal mobility.

Resort to fractal geometry for analysing the spatial organisation of urban and suburban fabrics prompts the use of fractal logic to develop a concept of sustainable development. The objective is to avoid the fragmenting of urbanised and natural areas and to simultaneously propose ready access to recreational areas close to residential areas. Moreover, the aim is to optimise access to services and businesses depending on the frequency of use by promoting the use of public transport and soft modes of transport. The concept is similar to the logic of 'transit-oriented development'.

Simulation of a TOD-style (transit oriented development) development scenario promoting development along transport routes while respecting an urban hierarchy.






  Step 2                                            Step 3


The various steps correspond to customer areas of the various central places of different levels. The colours indicate a surplus or shortfall in population compared with the average population of urban centres at each level.
