Abstract
This paper introduces key concepts used to formulate day-to-day scheduling of
the Tokaido Shinkansen, the main transportation artery linking Japan’s principal
metropolitan areas of Tokyo, Nagoya, and Osaka operated by the Central Japan
Railway Company (JR-Central). In order to schedule train services so that
passengers can always reserve a seat smoothly, we adjust the number of services
for every single operating hour throughout the year, by adding extra services in
addition to regular services to meet the demand of passengers, based on the
detailed demand forecast. In addition, we analyze unsatisfied and potential needs
by keeping a close eye on ticket sales information. For example, ticket sales
progress is used to tell us whether the sales were quick or slow. Quick and good
sales are an indication of strong potential needs. We add extra services promptly
when the sales are faster than expected. If the Shinkansen is crowded with few
seats available, it would be inconvenient and uncomfortable for
passengers. Furthermore, even when there are travellers who would choose the
Shinkansen if a ticket were available, we may lose the opportunity to serve them
if there are no seats to sell. Therefore, we at JR-Central aim to respond to
passenger needs, suppress congestion, and avoid fully-booked-up situations. As
above, this paper focuses on the measures taken to avoid congestion and
maintain efficient and smooth transport services for passengers. Minute and
flexible tuning of timetables, along with scrupulous and expeditious scheduling
approaches, is a feature of the Tokaido Shinkansen, the most densely scheduled
high-speed railway in the world, operating up to 12 train runs per hour per
direction and more than 370 train runs per day and serving approximately 410
thousand passengers a day.
