I have 3 files a bus route network, road network and bus stops. I want the bus stops to be the connections between the road network and the bus route. When I try and build the network dataset I am getting a standalone user-defined junction error. I tried snapping the stops to the bus route and building a network dataset with just these 2 files but still got the same error. I followed the instructions from here Snap point to line in ArcGIS to do that. Does anyone have any suggestions on what I can do to fix this?

what problem are you trying to solve? Optimal bus routes? – Craig Mar 3 '14 at 19:42

My first suggestion would be to investigate the geometries involved. Note that snapping is not enough - the layers must be coincident, meaning in order for a network junction to occur there must be a vertex at the same point in all related layers. You can't just snap the stop points anywhere along a route segment/edge (nor for that matter will a junction occur just because a bus route line and a street line cross).

The second suggestion would be from the help files where there is a specific solution outlined for correcting standalone junctions (note it's in the geometric network section rather than the network analyst section):

  1. Add the Geometric Network Editing toolbar to ArcMap.
  2. In the ArcMap table of contents, select one of the feature classes that participates in the geometric network containing the illegal features.
  3. Click the Network Build Errors command to identify illegal features.
  4. Locate the standalone junction to correct - These will have a build error code of 16.
  5. Correct the junction in one of two ways:
    • Delete the junction
    • Connect the junction to the preferred edge feature

First you should snap points to lines .You can use GME (Snap Points to Feature ). If you want to use bus stations for routing you should create multimodal network.Follow the Multimodal network excercise. You should create stations,entrances, Bus lines , use ovverride for entrances then build your network dataset.

I had the same problem and read this post hope it will help you, just exclude the stops in the network, it worked for me.

We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.

While this post may be helpful for the asker to read, your Answer would be more valuable if you described the steps that you are proposing in some detail. – PolyGeo Mar 3 '14 at 21:10
Also, since the asker specifically wants to use the stop locations as the connection points between the two modes, how would excluding them help solve the problem? – Chris W Jul 21 '14 at 2:11
While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes. – Devdatta Tengshe Jul 21 '14 at 3:34
