Modelling and simulation for sustainable and smart mobility

Micromobility: personal mobility devices (PMDs)

Building on recent projects (Ornisim, E3S, a Franco-German ANR project currently under development), the laboratory aims to meet the needs of local authorities in terms of planning and management, as well as those of the insurance sector. To this end, we are working on modelling the microscopic behaviour of PMDs (interaction with pedestrians, other PMDs, vehicles and two-wheelers, demand behaviour and journey tracking). We are also working on micro-macro modelling for planners and managers.

Modelling of very large networks

Building on our work on scale integration in travel modelling, and drawing on recent projects (DRIEA, E3S), we are continuing to work on the Magister platform, incorporating a two-dimensional approach to road traffic modelling. More generally, we are working on modelling very large networks using a hybrid approach: two-dimensional (dense surface network) + GSOM model (structural network). Various applications stand to benefit from these developments, in particular dynamic allocation, the analysis of externalities, and the management and planning of these networks. This project is closely linked to the ‘multimodal modelling and simulation’ section above.

Analysis of the resilience of transport networks

In an urban context where transport networks – complex and operating at near-capacity – are subject to significant pressures (traffic disruptions, major events, or even terrorist attacks), resilience is becoming a key issue. The laboratory is addressing this by developing a dynamic operational tool that adapts to changes caused by performance degradation with minimal loss of network functionality. To this end, the DESCARTES platform, dedicated to the assessment and regulation of resilience, is currently under development. This platform, which is now operational for the assessment of public transport networks, will be extended to multimodal networks and their regulations.
