Can network datasets from different locations be merged?

[RyanSnead]

Hello, I have generated many public transit network datasets across the state of Pennsylvania by local authority (e.g., Southeastern Pennsylvania Transportation Authority and Pittsburgh Regional Transit). I would like to merge them all to run a service area analysis based on provider facilities across the state. I could run the analysis for each local authority separately but that would take quite a long time and I have four sets of providers. Is there a feasible method to combine all of my public transit network data sets so I only have to run four analyses rather than over 40? Thanks!

Hi again, Ryan.

You can't really combine existing network datasets, but you can definitely combine multiple public transit agencies into a single network dataset.  The GTFS To Public Transit Data Model tool allows you to input as many different GTFS datasets as you want.  You will need a single feature class of street features, so if you have a separate one for each city, you'll need to merge those in advance.

Okay, that's not bad. Thanks again, Melinda! Everything worked smoothly after sorting out the last SQL issue.
