6 The Traffic Network
● PT stop active: Allows to activate or deactivate a PT stop (for the
current line only). A deactivated (= not served) PT stop is displayed as
green.
● Departure time offset: Option to define a schedule-based departure at
this stop that will be used in addition to the passenger interchange time.
The resulting departure time is calculated as follows:
arrival simulation second + dwell time +
max (0,
( (PT line Start time + Departure time offset)
- (arrival simulation second + dwell time))
• PT line Slack time fraction).
In other words, if the scheduled departure time is later than the sum of
arrival time + dwell time, then the PT vehicle will wait until the scheduled
departure time is reached, if the slack time fraction is 1. In case of lower
the slack time fraction values the vehicle departs proportionally before its
scheduled departure time.
If either the Slack time fraction or the Departure time offset is 0, then this
schedule-based operation is inactive and the dwell time is determined
according to the current settings in the Dwell time section.
Section Dwell Time:
Decide how the dwell time of the PT line vehicle is to be determined by stop
event.
As you can see from the image below, some of the PT stop parameters are
regarded only by a micro-simulation.
For a micro-simulation, pedestrian areas with Public transport usage (type
Waiting area or Platform edge) need to be allocated to the PT stops, cf.
section 7.1.4.3.
