Using the closest facility tool, I've noticed that when I try to figure out the shortest distance between two nodes there are some discrepancies. Case in point, I'm trying to connect nodes to several transit locations - trying to see which routes are closest to transit in the surrounding communities. I have 10 transit stations (Facilities) and about 700 nodes (Incidents). Some Incidents are not being routed to the closest Facility. There's no hierarchy in my network dataset, it's just a bare bones one (just using TIGER files in which I ensured its topological accuracy and checked for dangling nodes). Any thoughts would be greatly appreciated! It's only happening a few times out of hundreds so it's not terrible but still a little puzzling.
