The following options are available:
- No red flag (NoRedFlag)
Standard behaviour: The traffic stream remains green until it is switched to red by a conflicting traffic stream.
Figure 60: Red flag: No red flag
- No traffic (noTraffic)
The traffic stream switches to red as soon as there is no more traffic. The frame signal is ignored.
Figure 61: Red flag: No traffic
- Up to extension frame (upToSFext)
The traffic stream switches to red at the latest at the start of the frame for extension.
Figure 62: Red flag: Until start of frame extension
In the case of overlapping traffic streams (several traffic streams are assigned to the same display element), vs | plus checks whether the red detection of the others can also be executed. If this is not the case, the red detection does not take effect.
Red flag does not take effect in the "Advance" area, but only at the start of the frame for extension.
- Until frame end (upToSFend)
Der Verkehrsstrom schaltet spätestens am Rahmenende für Verlängerung auf Rot.
Figure 63: Red flag: To end of frame
- Up to tg min 1 (uptotgmin 1)
The traffic stream switches to red after the minimum green time 1 (tg min1).
Figure 64: Red flag: Until minimum green time 1
- Up to tg min 2 (uptotgmin 2)
The traffic stream switches to red after the minimum green time 2 (tg min2).
Figure 65: Red flag: Until minimum green time 2
- Up to tg max 1 (uptotgmax 1)
The traffic stream switches to red after the maximum green time 1 (tg max1).
Figure 66: Red flag: Up to maximum green time 1
- Up to tg max 2 (uptotgmax 2)
The traffic stream switches to red after the maximum green time 2 (tg max2).
Figure 67: Red flag: Up to maximum green time 2
- Until conflicting call (upToConflCall)
The traffic stream switches to red as soon as an conflicting is requested.
Figure 68: Red flag: Until conflicting call
The request is valid if a request time counter (twdet) assigned to the traffic stream is greater than zero.
From vs | plus version 8.0.0: Problem with minimum red time fixed: If the minimum red time is very long, it covers the signalling frame. The red flag now checks the minimum red time of the conflicting traffic stream.
- Until conflicting request (upToConflAppl)
The traffic stream switches to red as soon as an conflicting traffic stream is requested.
Figure 69: Red flag: Until conflicting request
The registration is valid if its traffic stream waiting time (twts) is greater than zero. The prerequisite for this is that a request time counter (twdet) assigned to the traffic stream is greater than zero and the frame for call is available.
From vs | plus version 8.0.0: Problem with minimum red time fixed: If the minimum red time is very long, it covers the call frame. The red flag now checks the minimum red time of the conflicting traffic stream. In addition, a frame signal for extension checks whether a conflicting call exists.
- Until conflicting frame (upToConflFrame)
The traffic stream switches to red as soon as a conflicting frame is pending. This happens regardless of whether the conflicting traffic stream has been requested or called.
