Network-Wide Mesoscopic State Estimation based on a Variational Formulation of the LWR Model and using Lagrangian Observations

Abstract

Traffic Granular Flow, DELFT, PAYS-BAS, 28-/10/2015 - 30/10/2015; This paper presents a generic data assimilation framework based on a mesoscopic-LWR model formulated in Lagrangian-space coordinates and using both Lagrangian observations. This is a challenge work since probe trajectories are not directly related to specific vehicle/platoon indexes in the simulation model. Therefore, we develop a method to incorporate probe information and to further estimate states. The proposed method has been validated on a homogeneous road stretch, and it provides promising results for further extension of the framework.
