Local feedback-based mainstream traffic flow control on motorways using variable speed limitsLocal feedback-based mainstream traffic flow control on motorways using variable speed limits Σύντομη Δημοσίευση σε Συνέδριο Conference Short Paper 2015-11-092010enRecent research has proposed mainstream traffic flow control (MTFC), enabled via variable speed limits (VSLs), as a novel motorway traffic management tool and has demonstrated its efficiency based on sophisticated optimal control methods that may face difficulties in practical field implementations. A simple local MTFC feedback controller is designed in this paper, taking into account a number of practical requirements and restrictions. The MTFC controller relies only on readily available real-time measurements (no online model usage and no demand predictions are needed) and is therefore robust and suitable for field implementations. The controller is evaluated in simulation and compared with optimal control results. Despite its simplicity, the new controller's performance is shown to approach the optimal control results while considering several practical and safety restrictions for a number of investigated scenarios.http://creativecommons.org/licenses/by/4.0/1261 - 12763rd NEARCTIS Workshop Papamichail Ioannis Papageorgiou Markos Παπαγεωργιου Μαρκος Carlson, R.C.
