Abstract

Measuring successful introduction of the access mode choice behavior with concerning the customer satisfaction is vital to improve the attractiveness of the service sector of public transport. This study examined a model with a statistical approach of Structural Equation Modeling (SEM) to assess the affection of access mode choice to select the main public mode for regular travel purpose by using the data from a Stated Preference (SP) survey conducted to Colombo Metropolitan Area (CMA) in Western Province of Sri Lanka. From the results of final model estimation, it was revealed that the access mode choice affected to the decision of choosing public main mode and first select the main public mode and then select the access mode for traveling.
