A generic integrated feedback-based motorway traffic flow control concept has been proposed recently by the authors of this paper. It is based on the combination and suitable extension of control algorithms and tools proposed or deployed in other studies, such as ramp metering or VSL (Variable Speed Limit)-enabled cascade-feedback mainstream traffic flow control, and allows for consideration of multiple bottlenecks. The new controller enables coordination of ramp metering actions at a series of on-ramps, as well as integration with VSL control actions towards a common control goal, which is bottleneck throughput maximization. While doing this, the approach considers a pre-specified (desired) balancing of the incurred delays upstream of the employed actuators, via a suitably designed knapsack problem. Despite the multitude of the offered configurations, options and possibilities, the generic control algorithm remains simple, efficient and suitable for field implementation. The control algorithm is demonstrated and evaluated using validated macroscopic traffic flow models for two case studies and for a number of different scenarios.The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP/2007-2013) / ERC Grant Agreement n. 321132, project TRAMAN21. http://creativecommons.org/licenses/by-nc-nd/4.0/8th International Congress on Transportation Research in GreeceProceedings of the 8th International Congress on Transportation Research in GreecePapamichail_et_al_ICTR_2017.pdfChania [Greece]Library of TUC2018-04-16application/pdf926.0 kBfree Papamichail Ioannis Παπαμιχαηλ Ιωαννης Iordanidou Georgia-Roumpini Ιορδανιδου Γεωργια-Ρουμπινη Roncoli Claudio Roncoli Claudio Papageorgiou Markos Παπαγεωργιου Μαρκος Traffic management Integrated motorway traffic flow control Ramp metering Mainstream traffic flow control Variable speed limits Feedback control Delay balancing
