Position Accuracy with Redundant MEMS IMU for Road Applications
Philipp Clausen,Jan Skaloud,Pierre-Yves Gilliéron,Bertrand Merminod,Harris Perakis,Vassilis Gikas,Ioanna Spyropoulou +6 more
TL;DR: In this article, the authors focus on the positioning assessment of vehicle trajectories collected by different navigation sensors (GNSS and redundant MEMS Inertial Measurement Units (R-IMU)) in real test scenarios.
Proceedings ArticleDOI
Towards distribution-based calibration for traffic simulation
Constantinos Antoniou,Vassilis Gikas,Vasileia Papathanasopoulou,Thanassis Mpimis,Ioulia Markou,Harris Perakis +5 more
TL;DR: This research explores the use of distributions of collected data (such as accelerations, using opportunistic sensors, such as smart-phone accelerometers) for calibration purposes, and proposes a methodology for the integration of data in traffic simulation model calibration and validation.
Journal ArticleDOI
A Data-Driven Model for Pedestrian Behavior Classification and Trajectory Prediction
Vasileia Papathanasopoulou,Ioanna Spyropoulou,Harris Perakis,Vassilis Gikas,Eleni Andrikopoulou +4 more
TL;DR: The objective of this research is to predict pedestrian movement in various perspectives utilizing historical trajectory data to provide a thorough description of pedestrian movement prediction, whilst contributes to the context of pedestrian modeling and Intelligent Transportation Systems.
Proceedings ArticleDOI
Collaborative navigation field trials with different sensor platforms
Allison Kealy,Guenther Retscher,Azmir Hasnur-Rabiain,N. Alam,Charles K. Toth,Dorota A. Grejner-Brzezinska,Terry Moore,Chris Hill,Vassilis Gikas,Chris Hide,Chris Danezis,Lukasz Bonenberg,Gethin Wyn Roberts +12 more
TL;DR: The presented preliminary results of the field experiments show that a positioning accuracy on the few meter level can be achieved for the navigation of the different Platforms, based on mass users of multiple-sensor platforms.
