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.

My PhD, supervised by Prof. Ludovic Leclercq, head of the LICIT lab (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).

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.

Traffic engineering and the development of simulation tools

I joined NEOVYA Mobility by Technology in 2020 as a R&D traffic simulation engineer for urban projects.

At Neovya, my tasks put all the knowledge and expertise learned during my PhD into practice. They consists in developing efficient simulation tools for the cloud-based Neovya Hubsim solution. This includes traffic flow models, route choice models, agent-based models, air quality and noise models. All these simulation tools are used to carry on studies for traffic operators.
