DriveTime Methodology - Help page incomplete sentence [no node within search radius]

[RickPack]

What is the completion of this language from the DriveTime Methodology help page, following "explained on"? Thank you.

"In rare cases it is possible that no node is found within the initial search radius and therefore the road network is not joined. This is explained on."

The way that I read it is that while a latitude and longitude is known, that point is far enough away from a known road that it can't be connected to a route. 

cheers,

Hi @RickPack 

That documentation page was copied from the original source: a Word document that used to be circulated with the data installation. In the original document, the complete line is "This is explained on Page 4". Page 4 is the part of the documentation that explains the off-road buffer process, which also applies if a node is not found. You can test this in Alteryx by placing a point far from your road network (like in a body of water) and you'll see that the resulting polygon is a circle, which is the off-road buffer to the duration of the specified drivetime. 

I've attached the original document from 2013 for your review. Let me know if you have any questions.
