Latent Class Model to Test the Preferences Heterogeneity in the Perceived Information by Public Transport Users

Research output: Contribution to conferenceOther

Abstract

The aim of analysis is to understand as not reliable information influencethe user behaviour and how much disincentive the public transport use. For thispurpose, a Stated Preference Survey has been carried out in order to know thepreferences of public transport users related to information needs and uncertainty onthe information provided by Advanced Traveller Information System (ATIS). Theperceived uncertainty is defined as the information accuracy. In our study, it wasconsidered the difference between forecasted or scheduled waiting time at the busstop and/or metro station provided by ATIS, and experienced one by user, to catchthe bus and/or metro respectively. A questionnaire has been submitted to a sample ofPalermo’s population. A Latent Class Logit model have been calibrated, taking intoaccount attributes of cost, information accuracy, travel time, waiting time, and cutoffsin order to reveal preference heterogeneity in the travel choice behaviour due toperceived information. The calibrated model has showed various sources ofpreference heterogeneity in the perceived information of public transport users ashighlighted by reported analysis.
