I wanted to see if you are aware of any North America Road network which has travel time integrated in it already (could be available via AGOL) which I can use to create service areas in Network Analyst? Thank you in advance.
The Streetmap Premium has travel times for North America. You can read more about it here:
StreetMap Premium for ArcGIS | Street Dataset | Geocoding Addresses
This data is also embedded into the AGOL logistics services that you can access on ArcGIS.com. Service Areas are supported in the AGOL logistic services.
