CORRIDOR 10 - a sustainable way of integrations
the train that starts before the calculation period begins, but then proceeds to pass part or all
of the calculation step in the calculation period (2.c.) (only in ÖBBmethod, in DB-method this
train is discarded).
Figure 5: Path compression [8]
In cases 2.a. and 2.b., the start of the block section occupation in the first block section of the
calculation step is moved to the start of the calculation period. In example 2.c., the train path remains
in the same position. When condensing the timetable the following train is pushed to the block section
occupation of train ahead, but the starting time of this train inside of the calculation step is maximum
adjusted up to the start of the calculation period, so that gaps between the block section occupations
may occur. Compression always begins at the start of the calculation period. Timetable compression
stops upon reaching the train whose first occupation is fully within the calculation period and is
performed until its final occupation inside of the calculation step.
5.4 The resulting infrastructure occupation (line Pragersko-Ormož)
The resulting infrastructure occupation time is measured at the beginning of the calculation step. The
infrastructure occupation time is defined as the time from the start of the calculation period to:
the end of the first occupation of the final train in the ÖBB-method,
the beginning of first block section occupation of the "Dummy-train" in the DBmethod
The results of the compressed paths for line Pragersko-Ormož are displayed in the figure below.
