列車運行実績データの可視化手法とその評価

抄録

Historical train traffic records are useful for identifying the cause of delays and to trace the propagation of delays. However, because the volume of the records is huge, visualization algorithms are necessary. In this paper, we introduce three methods; namely a chromatic diagram, a delay diagram and a 3D diagram. Then we show the results of evaluation by professionals who are engaged in timetabling.
