Contributions à la modélisation et la commande des réseaux de trafic routier

Abstract : The main objectives of this thesis are to propose dynamic models in order to describe road traffic by adapting models of fluid mechanics and based on these models to design and implement control algorithms. Road traffic is seen as a complex system organized in a decentralized structure. At the highest level of complexity there is the traffic network, considered as a part of a city’s road infrastructure. At the next level, the network is decomposed into traffic objects represented by road sections (streets) and intersections. At the last level of complexity there are the road segments that are parts of a road section.The thesis is organized into six chapters. The first chapter presents specific problems of road traffic networks, as well as control models and algorithms found in literature. The second chapter presents the main tools needed to describe a macroscopic traffic model, and some ways of representing the flow of vehicles. In the third chapter, dynamic models are proposed for different road segments and sections. The fourth chapter is devoted to designing algorithms for traffic control and optimization, including a robustness analysis to evaluate the system’s tolerance to model nonlinearities. The fifth chapter presents a control strategy for the road network, using the representation with compartmental models and the concept of positive dynamic. In the last chapter of the thesis, the author’s contributions are highlighted and some perspectives for further development of the research are presented
