Re: [Tagging] symmetrical guardrails
My original question arouse from guardrails that separate a cycle path from the road. The normal approach here is that the smooth inner side is towards the car traffic and the rough side (support structure) towards the cycle path. In the examples http://www.mapillary.com/map/im/9-9-x8ynIiIdpNQHeA5CWg the approach is more cycle-friendly by offering smooth sides to both, cars and cycles. The entire structure is maybe 0.3m thick. I was thinking of using an additional tag like symmetric or both for these, as it would be a lot of work to model them as double ways.

Just draw a closed way.

Often you find perfectly symmetric guardrails (example: http://www.mapillary.com/map/im/9-9-x8ynIiIdpNQHeA5CWg) I would like to tag this fact.

Re: [Tagging] symmetrical guardrails
Depending upon which side of the road the guardrail is on, either the left side or right side may be inner. If there is a distinct inner and outer side, the inner side will always be towards the traffic. -- John F. Eldredge -- j...@jfeldredge.com Darkness cannot drive out darkness; only light can do that.

Japanese motorway barriers. https://goo.gl/maps/7iZrg https://goo.gl/maps/7iZrg Countryside https://goo.gl/maps/qNir5 https://goo.gl/maps/qNir5 Urban There are some guardrails which share support poles with the one for the opposite road, the total set being about 50-80cm wide. If they used separates poles, and had any kind of a gap between them, I could see drawing two ways to represent both guardrails. Unless it is very easy to map both sides of the guardrail ( there is a gap) or putting two ways running in opposite directions on the same nodes, (to represent both guardrails), wouldn’t a “both” value of some kind (like for embankment) be reasonable in some instances?

Re: [Tagging] symmetrical guardrails
That seems reasonable. I was responding to the idea, stated in the original definition, that the right side of a guardrail would always be the inner side of the guardrail, and the left side would always be outside. In practice, guard rails can be present on either, or both, sides of a roadway, particularly if it is on a raised embankment. The side towards the traffic will be the inner side. As you said, a guardrail dividing two ways may have two inner sides if the supports are shared. -- John F. Eldredge -- j...@jfeldredge.com Darkness cannot drive out darkness; only light can do that.
