I have a question about start and end point in network analyst. I have a multimodal net with streets (lines), buslines (lines) and busstops (points). When I calculate the Closest Facilities the start snapps on a busline or street, but not on an busstop. How can I configurate the net, that the startpoint is only on the street (line) or a busstop (point)? What ist the best way? Shoud I do that with hirarchy, Z-coordiantes, restrictions? Other suggestions?
