VISSIM 5.30-05 User Manual

6 The Traffic Network
- For passengers available as type of pedestrians, the volume is
defined by relative flows.
● Alighting percentage: If option Calculation has been selected, enter the
percentage of passengers that alight at that stop. This value serves for
volume-based dwell time calculation.
No further calculation parameter settings required for pedestrians that have
been defined as vehicle type.
For users of the Pedestrian add-on, two more options are provided
additionally for calculation:
● Alighting composition: Select the appropriate composition of PT
passengers from the list of compositions that were pre-defined via menu
TRAFFIC – PEDESTRIAN COMPOSITIONS. Inside the PT vehicle, the
pedestrian types are created according to selected composition and the
user-defined percentage will be applied.
● Alighting location: Select the appropriate distribution of alighting PT
passengers from the list of distributions that were pre-defined via menu
BASE DATA – DISTRIBUTIONS – LOCATION. Inside the PT vehicle, the
pedestrians who want to alight at this stop, are distributed accordingly to
the doors of the vehicle.
● Alighting possible: Separately for Alighting and Boarding events, the
option possible can be checked for either side (left/right) of the vehicle
(due to door placement and use).
An arrow in the PT vehicle footprint indicates the direction the PT line is
heading to.
● Late boarding possible:
If this option is active, the minimum stop time is definitely kept and
furthermore the vehicle will not depart until all boarding passengers are
on-board. The doors are closed after three seconds without boarding or
alighting events.
This option has to be checked, if neither option Minimum is active nor a
timetable is used.
If this option is not active, minimum stop time = maximum stop time
applies.
- If slack time fraction = 0 applies, the vehicle will depart as son as the
minimum dwell time is over.
- If slack time fraction > 0 applies, the particular portion of the
remaining time until the departure according to the timetable will be
added to the stop dwell time, if the departure time has not yet come.
To make sure, that the PT vehicle leaves precisely at the time of
departure, if this option has not been checked, passengers can board the
vehicle only until the doors start closing.
Closing the doors takes three seconds. The doors also close if a
passenger boarded the vehicle right before closing the doors has started.
