7 Simulation of Pedestrians
● Behavior type: Optional property of areas, serves for modelling
occasional changes to speed or other parameters. Select a type from the
list of area behavior types defined via BASE DATA - AREA BEHAVIOR TYPES,
cf. section 7.1.9.2.
● Dwell time distribution: Optional property of areas. Select a dwell time
distribution from the list defined via BASE DATA - DISTRIBUTIONS - DWELL
TIMES, cf. section 5.2.6. This dwell time distribution will be applied to
pedestrians that pass this area due to their strategic route. Dwell time
distributions at input areas have no effect on pedestrians that are
inserted there.
For pedestrian areas with PT usage of either waiting area or platform
edge type, you can define a minimum dwell time by allocating a dwell
time distribution. PT vehicles do not depart until the minimum dwell time
is over or (even with minimum dwell time = 0) will depart later, when all
alighters will have deboarded. Optionally, you can check the option Late
boarding possible by PT line stop event, cf. section 6.5.2.5.
● Queuing: Waiting type attribute of rectangular pedestrian areas with
intermediate routing point or route destination point. If this option has
been checked, waiting pedestrians will queue for the duration of their
dwell time, or just for some seconds if no dwell time distribution has been
allocated. The queuing follows the direction vector that has been defined
during the creation of the area. The vector is displayed in center line
mode. This option does not work with pedestrian areas for public
transport usage.
● Public transport usage: Select the appropriate PT usage type.
- None: The area is not used by PT
- Waiting area: Location where pedestrians wait for the PT line they
want to board at the allocated stop. If at least one public transport
stop is selected, the pedestrians will choose a random point on the
waiting area and wait there for the next public transport vehicle. It is
currently not possible to model ordered waiting as a queue.
If the PT vehicle which the passenger intends to board has arrived
already the passenger does not follow his route to the randomly
determined position in the waiting area. Instead, he directly walks
towards the vehicle after reaching the waiting area as long as the
vehicle’s dwell time will last at least two more seconds.
- Platform edge: Location where pedestrians go to when alighting from
a PT line at the allocated stop. Alighting passengers will always use
the nearest platform edge. Then they follow the routing decision
placed on that area. If no routing decision has been set here, they
are removed from the network. For a platform edge, width = 2m is
required for minimum. An area (polygon type) serving as platform
edge can automatically be generated with a door, cf. section 6.5.1. A
platform edge can be allocated to multiple stops.
● For PT stop(s): Allocate one or several public transport stops to an area
of the Waiting area or Platform edge type.
