Building network of streets for generate service areas

  1. I have loaded the GTFS data into ArcGIS, and performed GTFS shapes to features and stops to features.
  2. I then created a Service Areas layer
  3. Then I added the GTFS shapes to features layer into the Facilities.

The only layers I have in my map are:

  • Service Area
  • Trip origins
  • Trip destinations
  • GTFSStops_to_features
  • GTFSShapes_to_features

My goal is to see if transit can service the trips - so the origin and destination must lie within 0.25 miles walking distance of transit stops. 

 

Can I execute Generate Service Areas with just the facilities loaded? I don't understand how it can calculate a service area with a walking distance impedance with just facilities? Do I need to import a street network in so it knows what paths a pedestrian can walk? Or is there already a pre-loaded universal street network in ArcGIS that it uses?
