Modelling of Travel Behaviour of Feeder Service for Intermediate Public Transport (IPT) Modes
摘要
Accessibility of public transport systems is limited in many developing countries primarily due to the lack of proper feeder services. The paper focuses on the development of feeder services based on intermediate public transportation (IPT) systems. Large numbers of commuters use public transportation systems, including local trains, buses and mass rapid transit (MRT) systems in developing countries. These need to be supplemented by feeder services to provide last mile connectivity. A feeder service can be made using IPT attractive by enhancing its mobility, easy access, convenience and comfort to its users. A stated choice (SC) survey instrument was designed and data was collected from commuters regarding their socio-economic characteristics and their travel characteristics including their choices in stated hypothetical scenarios. A stated choice survey was conducted among 392 respondents in a representative urban area, capturing user preferences for key attributes including travel cost, waiting time, safety, comfort, and reliability. For collecting data, respondents were approached randomly. Face-to-face interviews were carried out with all nominated respondents. Choice scenarios were formed using a different combination of values of the levels of attributes for different modes. The present study tries to develop a mode choice modelling for feeder service of IPT modes. Many types of modes are identified of feeder service which can find their utility functions using multinomial logit models by the econometric software NLOGIT 4.0. A Multinomial Logit (MNL) model was employed to analyse mode choice behaviour and quantify the influence of these attributes on feeder service selection. The results obtained from the analysis suggest that commuters consider safety to be the most important attribute of feeder service followed by comfort and waiting time. The findings of the study shall be useful for model development and analysis of choice behaviour.
