Measuring Travel Behaviour Changed of Travellers Using Latent Class Model for Discrete Choice Analysis

Abstract

This study analyses the factors influencing the behaviour of travellers before and after the construction of a new bridge in the Jayapura, Indonesia. This study used panel data obtained from the stated preference experiment and applied the latent class discrete model to determine the route choice. The latent class model results revealed that the survey respondents were divided into three clusters (groups/cohorts): convenient choice free traveller, a group of regular daily travellers such as commuters (45 per cent); captive travellers, most of whom depend on public transport or only orient with their existing vehicles (47 per cent); and conservative travellers, a group of travellers whose trips were casual and/or irregular (8 per cent). This research showed that there was a structural change between classes before and after the opening of the new bridge. The results of the study will assist local authorities to formulate appropriate land use and transport policies.
