Highway traffic state estimation with mixed connected and conventional vehicles: microscopic simulation-based testingHighway traffic state estimation with mixed connected and conventional vehicles: microscopic simulation-based testing Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2018-07-022016enThis paper presents a thorough microscopic simulation investigation of a recently proposed methodology for highway traffic estimation in the presence of mixed traffic, i.e., traffic comprising both connected and conventional vehicles, which employs only average speed measurements stemming from connected vehicles and a limited number (sufficient to guarantee observability) of flow measurements from spot sensors. The estimation scheme is tested using the commercial traffic simulator Aimsun under various penetration rates of connected vehicles, employing a traffic scenario featuring congested as well as free-flow conditions. It is demonstrated that the estimation results are satisfactory, even for low penetration rates.http://creativecommons.org/licenses/by/4.0/1761-176619th IEEE International Conference on Intelligent Transportation SystemsIEEE Conference on Intelligent Transportation Systems, Proceedings, ITSC Fountoulakis Markos Φουντουλακης Μαρκος Bekiaris-Liberis Nikolaos Μπεκιαρης-Λυμπερης Νικολαος Roncoli Claudio Roncoli Claudio Papageorgiou Markos Παπαγεωργιου Μαρκος Papamichail Ioannis Παπαμιχαηλ Ιωαννης Institute of Electrical and Electronics Engineers Vehicles Road transportation Estimation Microscopy Sensors Velocity measurement Testing
