How are the cross-section values of link labes calculated? At attributes like 'name' only one value of dircetion is suggested.

At the link labels the cross-section of both directions is suggested. What is suggested as cross-section can be defined for each link attribut. Many attributes get add up (i.e. number of routes, link volumes, user-defined attributes), for others, the average (i.e. v0 PrT), the maximum (i.e. length, link type, slope) or the minimum (i.e. plan no.) is suggested. For attributes that may contain text (i.e. name) there is no average - in this case the value of the direction whose start node is smaller than the destination node is taken. For user-defined attributes, the average-logic can be defined by the user.
