First-order traffic flow models incorporating capacity drop: overview and real-data validationFirst-order traffic flow models incorporating capacity drop: overview and real-data validation Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2018-04-162017enFirst-order traffic flow models of the LWR (Lighthill-Whitham-Richards) type are known for their simplicity and computational efficiency and have, for this reason, been widely used for various traffic engineering tasks. However, these first-order models are not able to reproduce significant traffic phenomena of great interest, such as the capacity drop and stop-and-go waves. This paper presents an overview of modeling approaches, which introduce the ability to reflect the capacity-drop phenomenon into discretized LWR-type first order traffic flow models; and also proposes a new approach. The background and main characteristics of each approach are analyzed with particular emphasis on the practical applicability of such models for traffic simulation, management and control. The presented modeling approaches are tested and validated using real data from a motorway network in the U.K. 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/Transportation Research Part B: Methodological10652-75Kontorinaki_et_al_Transport.
