Abstract

The railway centerline is defined by a polygonal line with some level of uncertainty in the train onboard database. The goal of this paper is to estimate the train speed by GPS and to study the impact of railway centerline uncertainty on the speed estimation. The equations for first two moments of the estimated speed are obtained and compared with the results of Monte-Carlo simulations.
