Another option, if you want to define a different VoT or VOC (vehicle operating cost) per vehicle type and trip purpose, is to define these values as an attribute of the User Class instead of using the Vehicle Type parameter. Activate the Types window, find the User Class type and double-click on User Class (GKUserClass) to access the Type Editor.

Click the Add button and create a new attribute of the type Double.

This attribute will now be available for any User Class. You can find it in the Attributes tab in the User Class Editor. Just fill in the values and access this attribute in the cost functions (for section, turn, or both).
