Cramer-Rao Bounds for Road Profile Estimation
(IEEE, 2017)In this paper, we study estimator accuracy in road profile identification. We derive a Cramer-Rao lower bound on the variances of all unbiased waviness parameter estimators for an ISO 8608 road profile, widely used in ... -
Parallel Track Models from Road Measurements
(IEEE, 2017)In this paper, coherence function estimation for parallel tracks from road measurements is studied. A two-stage scheme is proposed. In the first stage, the measurements are de-trended and periodic components are removed. ... -
Road Roughness Evaluation by Curve-Fitting and Subspace-Identification Methods
(Asce-Amer Soc Civil Engineers, 2016)In this paper, for a quarter-car model, root-mean square response variables are calculated for roads classified by the international standard organization, based on the straight-line spectrum models. Covariance expressions ... -
Road Roughness Modelling by Using Spectral Factorization Methods
(IEEE, 2016)In this paper, road roughness model for the right and the left tracks are constructed by utilizing two methods. In the first method, from time-domain measurements the empirical auto and cross-power spectral densities of ... -
Stochastic Models for Parallel Road Tracks
(IEEE, 2016)In this paper, we propose a method for constructing road roughness on parallel tracks. This method uses empirical power spectral densities and coherence of the left and the right-tracks estimated by non-parametric methods. ...
