Factors affecting the future utilisation of high-speed train services in Eastern Economic Corridor (EEC)

The high-speed rail project connecting three airports stands as a pivotal public transportation initiative, strategically designed to enhance economic growth within the Eastern Economic Corridor (EEC), Thailand. This study focuses on examining the factors influencing the future utilisation of this project. Mueang Chon Buri district, positioned at the heart of the EEC, is chosen as a case study. Data is then collected through a stated preference survey involving 400 randomly individuals, and a binary logistic regression model is constructed for the analysis. The results reveal that individuals with larger households and personal vehicles are less inclined to choose high-speed train services in the future, with probabilities of usage being 48.5% and 55.5% lower, respectively, compared to those with smaller households or without personal cars. To address this trend, service providers should undertake comprehensive public relations efforts and consider different pricing strategies. These measures have been found to enhance the likelihood of high-speed train usage by 3.097 and 1.411 times. In addition, the study also found crucial factors for successful high-speed train services, including station facilities, system reliability, efficient train schedules, and reduced travel time throughout the trip (emphasising seamless connections with other modes of transportation). Effective implementation of these factors could enhance public acceptance and usage of the high-speed train service in the region by 1.659, 2.089, 1.729 and 1.496 times, respectively.
