Outline of Final Research Achievements |
Recently, decrease in travel time reliability of commuter rail has become a serious issue. Then, an internet survey for railway commuters was conducted and 1000 respondents answered to the questionnaires. Arrival situation at the destination station was investigated and Kernel density of the difference between desired arrival time and actual arrival time was estimated for each respondent. Respondent was classified according to the similarity of the shape of Kernel density. All respondents were classified into 3 classes. Teacher data for SVM was made for each class. Every respondent was classified into 3 types by SVM. The departure time decision behavior under the travel time uncertainty was formulated and the buffer time model was estimated by adopting different distributions to each type. As the result, the classification of the respondents and adoption of mixture distribution model were available to estimate travel behavior of railway commuters.
