Identifies group of links, which start and end at the same two nodes. These might give problems in some networking algorithms ("emme/2" for instance).


RW Net has no problem with parallel links, unless you want to apply a turn restrictions from one parallel link to another and only want it at one of the 2 nodes they have in common.


The function returns the number of parallel links found.


The generated GIS file contains fields for:

Link: Original link ID

Group: 1, 2, 3 ....

SameLength: Logical value, which is true if all links in the group has the same length. This usually means the same link has been digitized twice.


Syntax: ParallelLinks(filename: string; GF: TGISformat): integer


In Standard version you are limited to networks with <10000 links.
