both sides. The default behavior has no restrictions: all doors on both sides
can be used for boarding and alighting.
Boarding pedestrians wait on a waiting area of a particular stop. In order that
a waiting area can be reached by pedestrians, it has to be defined as a route
destination.
Based on the boarding data of a stop, it is determined which lines the
boarding pedestrians want to travel with. If a vehicle of one of these lines
arrives at the stop, the boarding pedestrians walk straight to the nearest
door. Once, all alighting pedestrians have left the vehicle, the boarding
pedestrians board.
A vehicle departs from a stop as soon as the departure time is reached and
nobody has boarded during the last 3 sec. The departure time results either
from the timetable or from the preset dwell time. For the timetable-based
departure time the line´s Slack time fraction is considered.
For boarding passengers as well as for alighting passengers you can define
the distribution of the passengers to the doors. For boarding pedestrians,
select the distribution in the Pedestrian areas window, for alighting
pedestrians set the distribution in the PT stop data window. Use the option
Late boarding possible to configure how a PT vehicle having a timetablebased
departure time or a predefined dwell time for departure time
calculation will handle a never-ending flow of boarding pedestrians.
If a pedestrian was not able to board the vehicle, e.g. for capacity reasons,
the pedestrian moves back to a waiting area.
Default data for boarding pedestrians is also generated for a platform edge
or waiting area which has been allocated to a PT stop for which no boarding
passenger share has been entered yet. According to the default data each
pedestrian who arrives at one of the waiting areas of this PT stop, will board
the next vehicle of any line serving this stop.
Another improvement is the possibility to define doors for 2D vehicle models.
A door is defined by its position (relative to the leading edge), its width and
one of the vehicle sides.
For each door you can specify whether it can be used for boarding only or for
alighting only or for boarding and alighting as well.
These settings are stored in the Geometry window.
The properties of doors are derived automatically from the 3D model (if any).
The user can add or delete doors by using the context menu and modify the
data directly in the table in the [DOORS] tab.
If changed values do not match the 3D model a warning appears.
Nevertheless, you can confirm the new values. The data set in this window is
used for simulation only, whereas the 3D model values are used for the
visualization of opening/closing doors in 3D mode.
If not even a single door has been defined for a vehicle, a temporary door will
be created at the middle of the vehicle length. This way it is ensured, that
pedestrians can alight from the vehicle and board the vehicle. To provide this
information, a warning is logged to the trace file.
