A strategy to evaluate the satisfaction of different passenger groups.

Abstract

The Measure of the passenger satisfaction presents more difficulties like the measure of human performance, attitude. In this work a strategy based on Rasch analysis and Analysis of Means (ANOM) is proposed. This is based on the idea that the Rasch rating scale model gives ’sufficient statistic’ for an underlying unidimensional latent trait as the satisfaction generated by local transport operators. Furthermore, the ability of passengers, measured by the rating scale model, are studied by ANOM decision charts to verify if different groups have different level of satisfaction.
