I need some basic instructions on how to create a network dataset in ArcMap 10.1. I do realize there are esri tutorials out there but I'm having difficulty understanding everything. I'm just looking for a little help to get started.
What I want to do: perform Network Analysis on a potential new hospital site - I want to see how this new site will compare to an existing hospital location in terms of how many people it covers, accessibility, etc.
So first I need to create a Network dataset. I currently have streets and public transit route shapefiles, and I created 2 polygon features for the old and the new hospital location. What else do I need? Where do I go from here?
