Cyrille François is a postdoctoral teacher-researcher. His work focuses on the environmental issues associated with the daily mobility of individuals. He is interested in mobility, not in terms of the simple use of a technology but as a social reality anchored in a specific territory.

Liu Liu is a Civil Engineer with a PhD in Urban Planning. She drew up the “Transit Oriented Development” scenarios for the European Metropolis of Lille and participated in the development of energy transition strategies in Île-de-France.

Cyrille François and Liu Liu are currently working on Les Lumières Pleyel neighbourhood in Saint-Denis as an experimentation ground. This onsite work is part of their post-doctorate project at the École des Ponts ParisTech (Laboratoire Ville Mobilité Transport) in the framework of lab recherche environnement VINCI ParisTech.

This talk is co-organised as part of Leonard‘s “Ensemble pour demain” conferences.

The research work carried out at the École des Ponts ParisTech aims to anticipate mobility practices and services in the Les Lumières Pleyel neighbourhood as well as their impact on the environment. A statistical approach based on analysis of the socio-economic profiles of the individuals who will live and work in the neighbourhood aims to achieve an initial rapid estimate of uses and activities. This approach is then fine-tuned by multi-agent modelling that is aimed at a much more precise estimation of mobility needs and the effects of the implementation of new mobility services. The environmental impacts of associated mobility practices are then assessed through the prism of life-cycle assessment. It is therefore possible to assess the relevance of development choices and to propose solutions that are tailored to local characteristics, in order to improve the environmental performance of a neighbourhood.

STEM is a technical and economic model, intended to:

• quantify the different issues;
• simulate states of equilibrium between transport supply and mobility demand;
• seek out optimised states of the system by calculating action variables which optimise an objective function while satisfying imposed constraints.

The typical application is to seek a plan for the public transport prices and offer that maximises a function of collective well-being (sum of the surplus demand, operator profits and the monetisation of environmental impacts), while respecting a subsidy limit for the operation of public transport.

The eco-design of neighbourhoods requires various issues to be factored in: the socio-economic well-being and health of residents, the environmental impacts linked to the occupancy of buildings and the use of transport, the system effects which are at the origin of phenomena such as road congestion or development of a neighbourhood’s appeal.

The postdoctoral fellowship, led by Liu Liu at the École des Ponts ParisTech under the supervision of Fabien Leurent and Nicolas Coulombel, aims to model the daily activities and mobility of people who live or pass through a neighbourhood in order to deduce the economic, social and environmental impacts. The model considers microlocal conditions (the location of people, attractive services and infrastructures, demand for activities, available means of transport) and the interactions between an urban fragment and the rest of the agglomeration.
