Analysis of factors affecting the decision to select travel modes in Mahidol University Salaya Campus

Abstract

Mahidol University, Salaya Campus, has many intracampus traveling mode choices for travelers. Trips may be divided into two forms, active travel, and non-active travel. Examples of active travel are walk and bike cycling. Mode choices of students and staffs were explored in this study. The intracampus mode choices mainly have six modes; tram, bicycle, motorcycle-taxi, motorcycle-private, car, and walk. The survey of 923 samples about travel characteristics, satisfaction, and attitude was conducted. The proportions of each traveling mode were 39.7%, 20.8%, 15.7%, 9.4%, 7.4%, and 7.0% for trams, walking, motorcycle-taxi, motorcycle-private, car, and bicycle, respectively. Factors that most affect the level of satisfaction for active travelers were needing to exercise and not too hot weather. The nested logit model was developed. The significant factors were Distance, Cost and Travel time. The prediction accuracies were 83.23% and 83.15%, for the developed and validation data set, respectively. The investigated on modal shift were applied and analyzed.
