Traffic streams are prioritised using the priority elements in vs | plus. Each traffic stream that is to influence the control process must be assigned to a so-called priority class. There are two levels per class. 

Figure 36: 6 priority elements in 3 classes and 2 levels

Up to vs | plus version 8.x, you have the option of using 3 priority classes. From vs | plus version 8.1, the number of classes has been increased to 12.

Figure 37: From vs | plus 8.1 12 classes and 2 levels

A traffic stream is in level 1 when it is registered and can be moved to level 2 using the maximum waiting time parameter. 

As a starting aid (recommendation), the traffic streams can be divided into the following classes according to their type.

  • Class 1: normal traffic
  • Class 2: Public transport
  • Class 3: Emergency vehicles

With this first categorisation, the number of classes and therefore the priority elements can be selected. 

The individual priority elements have the following numbers.
