| Summary: | 碩士 === 國立臺中技術學院 === 事業經營研究所 === 94 === The paper is to study travelers’ choice behavior for intercity bus operators. We focus on the influences of service quality and inertia effect to the integrating model. This model is aimed to combine RP and SP utility based on the individual concept instead of data concept and to raise model’s explanatory power effectively.
Based on the past choice experiences of each traveler, a customized computer questionnaire was designed to collect the satisfying index of service quality for intercity bus operators. Then the choice scenario designed by stated preference method is used to analyze the choice preference of bus operators for travelers. This survey includes for major routes, Taichung-Tappei, Taichung-Taoyuan, Taichung- Tainan, and Taichung-Kaohsiung and adopts face to face interview to process data collection on the four bus terminals.
Sixteen evaluating criteria of service quality are identified and extracted to four common factors by using factor analysis. Those are safety and service attitude, comfort, convenience, and information provision. For correcting the bias of subjective specification for inertia effect, the logistic regression is used to construct the generalizing inertia index. Based on the individual viewpoint to combine RP and SP utility, we use the utility scale factor to conduct the scale difference between the two utility. The generalizing inertia index is also used to be the linkage variable between RP and SP utility.
By the likelihood ratio test between different specifications, we discuss the influences of service quality, generalizing inertia index, and utility scale factor on the integrating-utility model. The empirical results also show that the proposal specification has the better explanatory power than those previous specifications.
