The research thematic is about modeling, analysis, and simulation of agent-based systems. Applications rely on the safety of highway and urban traffic, driving automation systems, and pedestrian and evacuation dynamics.

Pedestrian and vehicle flows are both dynamical systems of self-driven agents interacting locally with partial knowledge of the environment. They are complex in the sense that the system performances can not be directly deduced from the individual behaviors of the agents. The dynamics describe non-linear phenomena and phase transitions to self-organized collective dynamics, e.g., lane formation or stop-and-go waves upon other coordinated behaviors and paradoxes.

We develop and analyze mathematical models and numerical simulation tools for pedestrian and vehicular dynamics based on differential systems, stochastic processes, or data-based algorithms. We calibrate, test, and validate the models using experimental and field data. The objective is to understand and predict traffic states and to devise safe and intelligent traffic solutions. We perform simulations and numerical analyses using open-source packages such as R or Python, and the simulation platforms NetLogo, JuPedSim, SUMO, CARLA, or GAMA.
