To display all paths in the flow bundles that do not traverse the selected network objects, show the alternative routes. Then only those OD relations are taken into account that use the selected network objects. If 60 % of the paths of an OD pair traverse the link s selected for the flow bundle, then the alternative routes make up the remaining 40% of the paths of this relation. These are the OD pair paths that do not traverse the selected link s.
In the example in Illustration 239, a link is marked as a flow bundle condition. All paths that lead across this link are displayed.
Illustration 239: Link flow bundle
In Illustration 240, a flow bundle of alternative routes is displayed for the same flow bundle criterion as in Illustration 239. For all OD pairs for which paths were found in the original flow bundle, the paths are listed that do not traverse the link selected. The comparison of the two illustrations shows that most traffic on these OD pairs uses the route closer to the city. A smaller share uses a long-distance bypass around the city. In a planning project the effectiveness of a created measurement could thus be allocated.
