Apart from safety and comfort, one of the goals is the alleviation of traffic congestion that is a major and challenging problem for modern societies. This thesis investigates the integrated use of two feedback control strategies utilizing VACS in different penetration rates, aiming at maximising throughput at bottleneck locations. The first control strategy employs mainstream traffic flow control using appropriate variable speed limits as an actuator. The second control strategy delivers appropriate lane-changing actions to selected connected vehicles using a feedback-feedforward control law. Investigations of the proposed integrated scheme have been conducted using a microscopic simulation model for a hypothetical freeway featuring a lane-drop bottleneck. The produced results demonstrate significant improvements even for low penetration rates.Thesis submitted in partial fullfillment of the requirements for the degree of Master of Sciencehttp://creativecommons.org/licenses/by/4.0/Πολυτεχνείο Κρήτης::Σχολή Μηχανικών Παραγωγής και ΔιοίκησηςMarkantonakis_Vasileios_MSc_2018.pdfChania [Greece]Library of TUC2018-09-14application/pdf10.4 MBfree Markantonakis Vasileios Μαρκαντωνακης Βασιλειος Papamichail Ioannis Παπαμιχαηλ Ιωαννης Papageorgiou Markos Παπαγεωργιου Μαρκος Nikolos Ioannis Νικολος Ιωαννης Πολυτεχνείο Κρήτης Technical University of Crete Bottlenecks Connected vehicles Traffic control LCC Lane Change Control VSL Variable Speed Limits VACS Vehicle Automation and Communication Systems
