A Conceptual Framework of a Travel Demand Modeling for a Public Transport System

This paper presents a conceptual framework relating to a demand modeling that links socio-economic, customer satisfaction and feeder bus system acceptance factors to the demand of the electric train services provided by KTM Malaysia. The model in this framework will serve as a predictive model for the demand pattern of ETS coupled with the demand for the services of its feeder bus system. The proposed framework will be developed with the theoretical underpinning as follows: activities based travel demand model, classic transport demand supply function, a unified theory of consumption and travel, utility theory travel demand model, and the theory of planned behavior. From these theories, four constructs and their measurement variables are highlighted in the study.
