<p>Hi Andrew,</p>
<p>From your description in example A, it sounds like you are describing frontage roads (what we would call service roads in Australia). Rather confusingly, the service tag isn’t the best tag for these roads; <a href="https://wiki.openstreetmap.org/wiki/Frontage_road">https://wiki.openstreetmap.org/wiki/Frontage_road</a> has a good explanation.</p>

<div dir="ltr">Hi Again,
<div> </div>
<div>With regards to service roads. I would like to know if there is a tagging convention that would provide a distinction between roads that appear to all fall under highway=service for the following examples:</div>
<div> </div>
<div>Example A: This is what is referred to "traditionally" as a "service road" (outside the OSM world that is). I'd describe it as,a minor road that is associated with a major road, it runs parallel to its major road counterpart and gives general access to the local area so that the major road is occupied by traffic that does not want to stop in the local area <a href="https://www.openstreetmap.org/way/118171809" target="_blank" rel="noopener noreferrer">https://www.openstreetmap.org/way/118171809</a></div>
<div> </div>
<div>Example B: A way (perhaps even a driveway or parking_isle?) that provides access to a carpark. It's not really paired with a major road and is not designed to "split" the local traffic from traffic passing through as per A <a href="https://www.openstreetmap.org/way/28262128" target="_blank" rel="noopener noreferrer">https://www.openstreetmap.org/way/28262128</a></div>
<div> </div>
<div> </div>
<div>The main difference I feel between A and B is that A is really part of a major/bigger arterial way and services the local needs that the arterial way will not. B is not really a thoroughfare and is more in line with the "destination" rather than a thoroughfare. You only use the B way to access the carpark(s). Someone else might have a better interpretation however I do feel like on the ground they are very different roads and tagging with highway=services alone doesn't reflect that.</div>
<div> </div>
<div>Thanks in advance,</div>
<div>Andrew</div>
