DATAHYKING MSCA Joint Doctorates Network (https:// datahyking.eu/) aims at training a new generation of modeling and simulation experts to develop virtual experimentation tools and workflows that can reliably and efficiently exploit the potential of mathematical modeling and simulation of interacting particle systems.
To this end, DATAHYKING unites researchers from 7 research institutes (KU Leuven, Università degli Studi di Ferrara, Università di Roma Sapienza, RWTH Aachen, Technische Universität Kaiserslautern, Université de Lille and INRIAi). This consortium will create a data-driven simulation framework for kinetic and hyperbolic models of interacting particle systems and define a common methodology for these future modeling and simulation experts. DATAHYKING will focus on:
We offer a fully funded 3-year joint PhD position between Inria Centre of Université Côte d'Azur and Università di Roma La Sapienza. The successful candidate will spend the first 18 months of this PhD at Inria (Sophia Antipolis, France), the next 18 months at La Sapienza (Roma, Italy). A 6-month secondment to Autovie Venete (Palmanova, Italy) is foreseen to work on an industrial case study.
ACUMES Project-Team (https:// team.inria.fr/acumes), leaded by Paola Goatin (https:// www-sop.inria.fr/members/Paola.Goatin/index.html), is a joint team from Inria Centre of Université Côte d'Azur and the Mathematics department Jean-Alexandre Dieudonné (LJAD) of Nice University. The research conducted concerns the analysis and optimization of systems governed by partial differential equations, with applications ranging from fluid and structural mechanics to modeling of biological phenomena, road and pedestrian traffic. In particular, ACUMES Project-Team has an established experience in (macroscopic) traffic flow modeling, simulation and optimization, including industrial and international collaboration.
The Department of Mathematics Guido Castelnuovo at University of Rome "La Sapienza" is one of the most important in Italy and takes a prominent place in the history of mathematics. The excellence of the research performed, together with the wide-ranging collaborative relationships maintained by researchers in the Department of Mathematics, guarantee the high quality of the doctoral program. In particular, the research group in numerical analysis gathers, among others, experts in multiscale mathematical modeling and high order finite volume schemes for conservation laws.
During the first phase at Inria, the PhD student will study micro-macro models consisting of coupled PDE-ODE systems to describe the mutual interaction between a finite number of particles and a fluid flow and allow designing efficient control strategies to regulate traffic flow by acting on the speed of a few controlled vehicles. She/he will develop new PDE-ODE coupled multilane models for the mutual interactions between the main (human-driven) flow and a small number of specific autonomous particles/agents. We will study the well-posedness of the resulting systems, develop numerical schemes to compute approximate solutions and study the dependence of model properties of interest on particle penetration rate.
The second phase at La Sapienza will be devoted to the development of mixture models, containing human-driven and a small percentage of autonomous cars. These models result in macroscopic flow models, coupled with ODEs for driver behavior. She/he will develop efficient numerical methods for these models and study the sensitivity of the stability of traffic flow with respect to the interaction rules at the microscopic level between autonomous and human driven cars, as well as the effect of partially autonomous cars with increasing levels of automation.
The secondment at Autovie Venete will focus on model calibration against real world data provided by the industrial partner.Main activities
After a complete literature review, the research fellow will develop and investigate multi-scale traffic flow models, including the well-posedness and other analytical properties and the development and coding of specific numerical schemes. She/he will also validate the results against real traffic data.
