Abstract
This study focuses on the importance of the acquisition of the passengers transferring data and application to the planning of railway station amelioration, and proposes an obtaining method of the behavioral data. It is important to use the 4-dimensionality path data of the passengers in interchange stations for the improvement of the transfer LOS. Little attention, however, has been given to the acquisition of the data, because the conventional planning has not considered the passengers behavior. The study develops an acquisition system of the 4-dimensionality path data of the passengers from the video images with the help of the image processing technique.
