Factors Affecting Decision-Making to Use Feeder Bus Services and Air-Conditioned Buses in Salaya Subdistrict Towards A Sustainable Transport Policy

Abstract

This research aims to study the factors affecting the public transport travel behavior of people in the community around Salaya station area. We distributed 375 questionnaires to examine the behavior of people in Salaya subdistrict municipality area and its environs. To promote sustainable transport, it is important to consider policy interventions that encourage the use of public transport and reduce dependence on private cars. Therefore, the study area has been chosen in order to give an insight into feeder bus planning will supports the commuter railway line that is to be developed in the near future. This study focuses on two research questions necessary for the feeder transport planning as factors that affect the choice of a feeder system to travel in the area and the factors that affect the choice of using the air-conditioned feeder bus. The behavior of the samples was analyzed by binary logistic regression in two steps: first, to predict the factors that affect the probability that people will use the feeder bus service that picks up passengers between destinations in SALAYA and between SALAYA and Bangkok. Second, to predict the factors that affect the probability of choosing an air-conditioned bus service. As a result, the demographic factors that appeared to affect the decision of choosing a feeder bus were income and the number of vehicles owned. Furthermore, the factors affecting the decision to use air-conditioned buses are age, education, and income. Understanding these factors can help local transport authorities for designing more effective shift-mode strategies.
