Macroscopic Traffic Flow Control via State Estimation

The studies presented in this paper deal with traffic control in case of missing data and/or when the loop detectors are faulty. We show that the traffic state estimation plays an important role in traffic prediction and control. Two approaches are presented for the estimation of the main traffic variables (traffic density and mean speed). The state constructors obtained are then used for traff...

Parameter estimation using macroscopic diffusion MRI signal models.

Macroscopic models of the diffusion MRI (dMRI) signal can be helpful to understanding the relationship between the tissue microstructure and the dMRI signal. We study the least squares problem associated with estimating tissue parameters such as the cellular volume fraction, the residence times and the effective diffusion coefficients using a recently developed macroscopic model of the dMRI sig...

On Parameter Estimation for Exponential Dispersion Arma Models

A class of autoregressive moving-average (ARMA) models proposed by J rgensen and Song [Journal of Applied Probability (1998), vol. 35, pp. 78–92] with exponential dispersion model margins are useful to deal with non-normal stationary time series with high-order autocorrelation. One property associated with the class of models is that the projection process takes the exact form of the classical ...

Fast Parametric Estimation for Macroscopic Traffic Flow Model

The main traffic parameters such as the critical density and the free flow speed of a motorway segments are subject to changes over time due to traffic conditions (traffic composition, incidents, . . . ) and environmental factors (dense fog, strong wind, snow, . . . ). As such parameters have an impact on the performance of the traffic control strategies, they must be estimated on-line. Our app...

Real-time travel time estimation using macroscopic traffic flow models

This paper presents the estimation of travel time on highways based on macroscopic modelling. The focus is on real-time values as compaved to average or static values. The macroscopic models are used for distributed and timehpace lumped settings and corresponding travel time estimation functions and algorithms are developed. The implications of these algorithms for the implementation of various...
