I am creating the network dataset for pedestrians. I have these layers:
1) footpaths which break when they intersect driveways or pedestrian crossings
2) pedestrian crossings (e.g. signalised crossings, zebra crossings)
3) permeability polygon layer (class 1-4 e.g. with fences (cannot pass through), with void decks, town centres promenades (pedestrians can walk everywhere)

A) the permeability layer did not auto appear in the new network dataset though it has been imported to file Geodatabase feature dataset - is there any criteria for the required layers to appera in the new network dataset?

B) In ArcMap, when i test the find shortest route.  "No route found" is displayed whenever it crosses the pedestrian crossings or when there is a gap in between the footpath layer.
How do i join the gap or how do i link it with the driveway layer to make the network continuous?
