Abstract
We propose an algorithm for automatic train rescheduling with a train
rescheduling pattern language processing system. Intended for restoration from
heavy train traffic disruption, our proposed algorithm has inherent abilities to
make effective train rescheduling plans. While the previous algorithm tries to
make a train rescheduling plan in small steps, the proposed one surveys the train
timetable at first and applies “train rescheduling patterns” to prepare
rescheduling plans. Applying actual train schedule data, we have confirmed that
our algorithm works satisfactorily. For severe train traffic disruption caused by
an accident, in particular, requiring the suspension of train operations for more
than an hour, the algorithm is helpful for preparation of adequate rescheduling
plans for practical application.
Keywords: train rescheduling, pattern description, train rescheduling pattern,
train traffic disruption, train traffic control, framework of train rescheduling
system.
1 Introduction
Train traffic is sometimes disrupted when accidents, natural disasters or technical
problems occur on railway lines. In order to restore disrupted services, railways
have continuously made a series of modifications to the current train schedules.
Such a task is termed as train rescheduling [1, 2]. It is quite important for railway
companies to prepare an adequate train rescheduling plan hereinafter referred to
“the plan” whenever train traffic disrupted.
Keywords
train rescheduling, pattern description, train rescheduling pattern,train traffic disruption, train traffic control, framework of train reschedulingsystem.
