The permitted transport systems specify the configuration of a link. The following types can, for example, occur:
- a simple road which can be used by PrT-vehicles and street-bound PuT
- a rail track which can only be used by trains (trains, subways)
- a road with tramlines
- a one-way road which can only be traversed in one direction
- a transfer walk link between PuT-stops
The Illustration 7 shows three examples for permitted transport systems on different types of links.

Illustration 7: Examples for defining transport systems of a link
The number of the lanes of a link is entered as an attribute, but also has to be considered for the capacity (this means that the entered capacity does not refer to one lane, but to all lanes). A link is always meant for both directions. In order to define a one-way road, close the opposite direction to all transport systems.
- Links which are open to PrT transport systems are taken into account during private transport assignment.
- Links which are open to PuT transport systems are taken into account during the construction of line routes for public transport lines. PuT assignments (headway-based or timetable-based procedures) are not based on link data, but on PuT line timetables.
To model passenger transfers between certain public transport stops, a special public transport system PuTWalk may be introduced. These links are taken into consideration for PuT assignments.
