- Stop only if: Activates the condition so
that the stop line is only active when the
following condition is true.
- If the selected Signal Group of the selected
SC (Signal controller) has the selected
Signal State then the stop line is active and
checks the other conditions as well (min.
headway, min. gap time etc.).
Non-Signalized Intersections
The following properties affect each conflict marker:
● Min. Gap Time: Minimum gap time (in s) between the conflict marker and
the next approaching vehicle.
● Min. Headway: Minimum headway (distance) between conflict marker
and next vehicle upstream.
● Max. Speed: Any vehicle approaching the conflict marker will only be
taken into account for the headway condition if its speed is the same or
lower as the Maximum Speed.
● Look beyond red signals: Also vehicles located upstream of red
signals are "seen" by the conflict marker. If deactive, headway and gap
time are only checked up to red signal heads.
