Abstract
We are studying railway operation optimization. Two kinds of trains, local and
rapid, are under consideration to investigate the optimization of rapid trains
stopping stations by adjusting the stopping stations to reach optimum
convenience and rapidity. However, the rapid train has to overtake local trains
that are running ahead. Therefore, overtaking facilities need to be considered too.
In this paper, we describe the relation between stopping and overtaking
station combinations and operation effectiveness. First, the rapid train stopping
and overtaking stations are determined by DP (Dynamic Programming),
considering real overtaking facilities at stations. Second, the rapid train timetable
is determined and drawn on the train diagram. Third, the local train timetable is
determined based on overtaking stations. The diagram is drawn for both
directions starting from the overtaking station. The evaluation value is the
average trip time, and is calculated by the timetable (diagram) and the passenger
OD (Origin and Destination) table. By computer simulation using an existing
line, we show that the most effective conditions are fewer overtaking stations,
and no simultaneous overtaking at a stopping station.
Keywords: rapid trains, combination of stopping and overtaking at stations,
train timetable, average trip time.
