7 Simulation of Pedestrians
Case 2: Vehicles yield to
pedestrians
On the pedestrian link, the
area from 3 m upstream to
the begin of the conflict area
serves as “detection area”
for pedestrians approaching
the conflict area (cf.
Detectors below).
Pedestrians inside the
conflict area are always
Detectors
taken into account.
The time gaps between (groups of) pedestrians when the conflict area is
expected to be completely free of pedestrians are passed to approaching
vehicles so they can react accordingly.
Detector areas are used to model push buttons for pedestrian signals.
The Detector object is also used as SCJ detectors for pedestrians. It has to
be placed on the pedestrian link where the signal head is located.

For definition of detectors for pedestrians and subsequent changes to their
properties please refer to the detectors for signal-controlled vehicular
traffic, cf. section 6.7.1.3.
[ACTIVATION] tab:
The parameters in this tab regard
whether the link has been defined
for pedestrian traffic or for vehicles.
For a pedestrian link please select:
● Maximum speed: Enter max.
speed value. Slower
pedestrians will be recognized
as demanders by the detector.
● Pedestrian classes: A
pedestrian is only detected if his
type belongs to the selected
class.
You can define priority rules not only for vehicular traffic, but also for
conflicting pedestrian flows and also for the interactions between vehicles
and pedestrians.
For pedestrians, a priority rule needs to be placed on a link that is
permitted for pedestrians. Pedestrians can be the yielding flow as well as
the flow having the right of way.
