A macroscopic multi-lane traffic flow model for ACC/CACC traffic dynamicsA macroscopic multi-lane traffic flow model for ACC/CACC traffic dynamics Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2019-08-302018enAn extended second-order macroscopic traffic flow model is presented that describes multi-lane traffic dynamics and also incorporates the effects of adaptive cruise control (ACC) or cooperative ACC (CACC). The extended model equations stem from a recently proposed multi-lane gas-kinetic traffic flow (GKT) model that can simulate lane changes due to vehicle interactions as well as spontaneous ones. The proposed extension that models the effects of ACC/CACC satisfies the time-gap principle of such systems on each lane and allows for consideration of mixed traffic comprising both manual and ACC/CACC vehicles. Numerical simulations are performed for a particular three-lane motorway stretch in the United Kingdom, where recurrent traffic congestion is observed during the morning peak hours, so as to compare the effects of ACC/CACC in the traffic flow conditions with those resulting from manual driving.http://creativecommons.org/licenses/by/4.0/Transportation Research Record267220178-192 Delis Anargyros Δελης Αναργυρος Nikolos Ioannis Νικολος Ιωαννης Papageorgiou Markos Παπαγεωργιου Μαρκος SAGE Publications Adaptive cruise control Kinetic theory of gases Motor transportation Extended model Traffic flow modeling
