[talk-ph] Request for clarification on road tagging guidelines

Thanks everyone for your time in clarifying us.

We found a couple of segments in PH and ID cities where the link segment
classification in continued as that of connecting way.  As mentioned by
Eugene and Maning, these could probably classified basis traffic flow and
segment usage.

So, if the connector segment is already available, we better off do not
change its existing classification as we will not be sure on the traffic
flow through satellite imagery alone, unless we have mapillary or OSC
imagery.

But, how would we go about when we find a missing connector.  Will it be a
good idea to tag it as highway = road?

Thanks
Lavanya

There is a list:

But not everyone agrees. ;)

Agree with Eugene here.  It depends on the traffic-flow and general purpose
of that segment.
