There is not much documentation on the wiki. The only thing that I found was a statement at http://wiki.openstreetmap.org/wiki/Tag:highway%3Dservice that says that highway=service is wrong, but everything else is okay. I agree that *_link is not good. (Also because you can often use the frontage road with smaller/slower cars than the main road.) As frontage roads are quite common in some countries, I think it would be useful to create a wiki page with some documentation and a best practice guide. Proposal for the content: – frontage roads are never highway=*_link nor highway=service – frontage roads have usually a lower level than the main road (which one is up to the mapper to decide) Example: If the main road is secondary, the frontage road must be one of “tertiary” or “unclassified” or “residential”.

(Also because you can often use the frontage road with smaller/slower cars than the main road.) Set it to unclassified currently for my example http://www.openstreetmap.org/edit#map=18/36.34904/139.28130 I quickly mapped out a frontage road along the secondary. As frontage roads are quite common in some countries, I think it would be useful to create a wiki page with some documentation and a best practice guide. I'm surprised to see so many new large roads here in Japan planned with extensive (and narrow, dead-ending near intersections) frontage roads. Every new major road in my area made int he last 2-3 years has them now. they all look similar to the one linked originally and my example. +1 Proposal for the content: – frontage roads are never highway=*_link nor highway=service – frontage roads have usually a lower level than the main road (which one is up to the mapper to decide) if it is not of (severely) lower importance, it isn't a frontage road. Example: If the main road is secondary, the frontage road must be one of “tertiary” or “unclassified” or “residential”. Tertiary max, if not unclassified max . I mean, a big road often parallels a major way, but this is mostly discussing local access being separated from the faster, adjacent road for traffic management reasons. I don't think there are going to be many beyond unclassified, as they are just chopped up little pieces of road just for local access to driveways and alleys. That might be a good test - if you think it is tertiary, it probably is't a frontage road, as these scream local access and nothing more. Could this be a useful guide?

I also do not see why we should exclude highway=service as a possiblity. It’s just raw guess, but maybe the intention of the statement at the wiki page was not to exclude highway=service, but to avoid mixing up concepts. Because sometimes frontage roads are called “service roads”, people might think that this was the _only_ valid tagging for frontage roads. However, in OSM highway=service is defined differently. So other values may be more usefull – overall highway=residential. Probably the wiki statement would just say this. as these scream local access and nothing more. Sometimes you have frontage roads who mostly don’t give local access. Example http://www.openstreetmap.org/?mlat=39.47925mlon=-0.45146#map=17/39.47925/-0.45146 Here the mapper decided to use “tertiary”. The road has mostly through-traffic. I would not make a strict rule for all cases, but just leave this up to the local mappers to decide.

A frontage road is any parallel road for local access, which is normally bypassed by the larger road. Tertiary is perfect for your example. I guess these frontage alleys in Japan are really small and cut up (less than 100m or so long, and dead-end to nothing).

[Tagging] Understanding links
I have a question on highway link roads. I came across some trunk_links that seemed really out of place today, but they were recently added by a tagger that usually knows what they are doing. https://www.openstreetmap.org/#map=19/36.30046/139.19574 The frontage road for local access to the buildings along the road is marked as trunk link. As I understand it, the local access roads would be an unclassified road with bollards or a kind of barrier at each end, and with trunk links, (or one way unclassified roads?) that lead onto the actual new trunk road. This seems like an incorrect use of trunk_links for the frontage road along the buildings and maybe for the little entrance exit driveways that connect it to the trunk roads.
