Abstract:
Although railways in Japan are known to be very punctual, we sometimes experience small delays of trains especially during the peak hours in urban areas. I will show some of our results to improve robustness of timetables using historical train traffic records; namely, a visualization method of historical train traffic records which we named the chromatic diagram, an algorithm to detect delay propagation routes based on the association rules, an algorithm to differentiate poor drivers and excellent drivers based on the decision trees and so on.

Biography:
Professor TOMII graduated from the graduate school of Kyoto University majoring in computer science. Then, he started his career in ex Japanese National Railways (JNR) and then joined Railway Technical Research Institute (RTRI) when JNR was divided and privatized. In RTRI, he consistently engaged in the research of scheduling algorithms in railways. Since 2007, he has been working as a professor in the department of computer science in Chiba Institute of Technology, where he is continuing research about scheduling algorithms in railways.
He was serving as a board member of Japan Transport Safety Board (JTSB) for about ten years, which is a national organization to conduct investigation to determine the causes of aircraft, railway and marine accidents.
Professor TOMII is also acting in international societies. He is the President of IAROR (International Association of Railway Operations Research) and serves as a conference co-chairperson of COMPRAIL (International conference on Railway Engineering Design and Optimization).
