Example 1: Motor vehicle with parallel PED

If, for example, a pedestrian is no longer allowed to switch to green when his parallel motor vehicle traffic stream is green, the motor vehicle traffic stream is considered to be decisive (it does what it wants) and the pedestrian is considered to be dependent. The latest permitted switching of the pedestrian is determined with dt.


Example 2: vs | plus internal locking tables

Assignment of traffic stream to display element:

From these two parameters, vs | plus now creates a new table containing the locking of the display elements.

The interlocks of the individual display elements are now determined using this new table and, if necessary, the corresponding corrections are made in the transitions.


To control the node, vs | plus also needs the interlocking information at the traffic stream level. A new table is now created internally with the assignment of the traffic streams to display elements.

This contains the interlocking at the traffic stream level

also due to the overlays.

The interlocking table of the traffic streams is very different from the original interlocking parameter table. These internal tables are built up dynamically by vs | plus as soon as the parameter base changes. The great advantage for the user is that only one traffic stream interlock needs to be parameterised, regardless of which display elements are used together. A display element that is influenced by an IT and a PT traffic stream only needs to be entered once.
