摘要

Bangkok Mass Transit system (BTS) is launched in 2000 with the aim to solve congestion problem by reduce number of cars on streets. Due to BTS characteristics of rapid and punctuality, it is believe that BTS gain the popularity as a major mode of transportation in Bangkok. The ridership records report that the number of riderships are significantly increased from approximately 55 millions in 2000 to 220 million in 2014, whereas the number of registered cars in Bangkok also increased. This poses a question on the effectiveness of BTS which lead to our investigation on factors affecting attitude toward behavior in using mass transit system in Bangkok. Theory of planned behavior (TPB) is employed to categorize factors effect-behavior as attitude, perceived behavior control, and habit. Attitudes toward behavior were attained through various literatures, then they were categorized according to the Marketing Mixed (4Ps) framework. Questionnaires were designed according to best-worst scaling framework [1]-[9]. There are 95 car users response to our survey. Survey data were analyzed with Best-Worst scoring system. The result shows that car users consider speed of travel (A1) and distance between station and ridership's origin/destination (D1) as the most influencing factors affect attitude toward the use of BTS.
