Traffic modeling for large-scale transportation systems

My research interests are about modeling and simulation of road traffic at metropolitan scales for traffic operations, management and control. With classical modeling tools, large-scale simulation requires extensive knowledge of individual trip patterns, hardly accessible in practice, and very long computational time which makes some real-time applications impossible. Therefore new models have arised to reduce urban network complexity, while still fairly reproducing congestion dynamics in metropolitan areas.

My PhD, supervised by Prof. Ludovic Leclercq (Lyon, France), was aimed at developing a macroscopic simulation platform for large-scale urban areas. This tool is based on the very novel Macroscopic Fundamental Diagram (MFD) concept, which describes congestion level in a homogeneous urban region. Road traffic flow in a city can then be represented by clustering the area into several regions that exchange flows of vehicles with each other. This modeling approach was validated through different comparisons with other existing simulation tools, and traffic data from Lyon's urban area (France).

(funny interpretation of the question on the MFD existence, the MFD being a network-wide extension of the Fundamental Diagram concept at a link level)

The MAGnUM Project

This thesis was supported by a European Research Council (ERC) grant entitled MAGnUM: Multiscale and Multimodal Traffic Modelling Approach for Sustainable Management of Urban Mobility. This project has received funding from the European Commission under the Horizon 2020 Research and Innovation Program.

LICIT lab: an ENTPE-IFSTTAR joint research laboratory

I am working at the LICIT lab (Transport and Traffic Engineering Lab). This one is partly located at the ENTPE school (National Engineering School for State Public Works), which is affiliated to the University of Lyon (France). This laboratory was initially part of the INRETS institute (National Research Institute on Transportation and its Safety), which merged some years ago with the LCPC lab (Central Lab from École des Ponts Paris) to create the IFSTTAR institute (French Institute of Science and Technology for Transport, Development and Networks). Since January, 1st 2020, follow-up to a merge with Paris-Est university, IFSTTAR became Université Gustave Eiffel.
