A generic integrated motorway traffic flow control concept is proposed in 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 maximisation. The approach enables a pre-specified (desired) balancing of the incurred delays upstream of the employed actuators, via a suitably designed knapsack algorithm. Despite the multitude of the offered configurations, options and possibilities, the overall control algorithm remains simple, efficient and suitable for field implementation. The control algorithm is evaluated and demonstrated using a validated macroscopic traffic flow model for a number of 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/4.0/315-32214th IFAC Symposium on Control in Transportation SystemsIFAC-PapersOnLineIordanidou_et_al_CTS_2016.pdfChania [Greece]Library of TUC2017-11-13application/pdf999.0 kBfree Iordanidou Georgia-Roumpini Ιορδανιδου Γεωργια-Ρουμπινη Papamichail Ioannis Παπαμιχαηλ Ιωαννης Roncoli Claudio Roncoli Claudio Papageorgiou Markos Παπαγεωργιου Μαρκος International Federation of Automatic Control Traffic management Integrated motorway traffic flow control Ramp metering Mainstream traffic flow control Variable speed limits Feedback control Delay balancing
