Abstract

The aim of the work presented here is the inverse identification of the railway tracks irregularities and more precisely the lateral offset using a railway dynamics software with measured irregularities as inputs. The broader goal is to use on-board sensors to identify track irregularities for the purpose of facilitating the maintenance of the railways. First of all, this identification involves the search for statistical correlations with the train’s accelerations and other irregularities. Then, an estimator is constructed in order to create an a-priori on the lateral offset irregularity.
