Traffic congestion imposes costs on the economy and generates multiple impacts on urban regions and their inhabitants. There are a number of specific circumstances which cause congestion; most of them reduce the capacity of a road worsening the situation. An optimal use of the capacity of the infrastructure can be obtained through suitable traffic control measures. After a presentation of the main properties of traffic and of the main reasons for infrastructure deterioration due to traffic congestion, this tutorial will address an overview of different existing methods of traffic control strategies. Freeway management control concepts; ramp metering; control concepts for single intersections; arterial streets and networks will be exposed.
Speaker - Neila Bhouri
Neila Bhouri is a Researcher at IFSTTAR (The French Institute of Science and Technology devoted to Transport, Planning and Networks). She obtained her PhD “Automatic control of a freeway transportation system” in 1991. Her research fields are related to multimodal urban and freeway traffic control strategies and systems and to transportation network analysis. Prior to joining The Grettia laboratory (Engineering of Surface Transportation Networks and Advanced Computing Laboratory) of IFSTTAR in September 1999, she worked as an Associate Professor in Automatic control theory mainly at the Naval Academy and the ENIT (Tunisian National School of Engineering). She also gave lectures on Transportation control and planning in different Engineering Schools. She acted as an expert in national and international committees (OCDE/ITF; MEDDAD/DGMT). She is also member of the board of Transportation Research Procedia (TRPRO)
