Render barriers bicycle access

[Florimondable]

How to know if a barrier let bicycle pass ? With bicycle=yes, so we could render them in blue. And in red/orange when bicycle=no ? I think the feature is realy usefull.

Examples yes : https://www.openstreetmap.org/node/6864894893 no : https://www.openstreetmap.org/node/721443597

Indeed. I would be more in favor of having grey by default and blue if bicycle can pass.

There are three states : unknown, bicycle=yes, bicycle=no so grey, blue, red/orange/yellow

[Phyks]

I would be in favor of considering unknown is the same as bicycle=no (as no precision likely means that bicycle are not allowed). Therefore, we could only consider:

• bicycle=yes in blue
• bicycle=no or unknown in grey

I'm not so much for having red/orange/yellow, this attracts too much the eye for something which is blocking.

[barrier=gate][bicycle=yes] is pretty useless to notice for a cyclist, In my experience, it's the same effect than [barrier=cycle_barrier], Maybe it is simpler to render them the same way. https://wiki.openstreetmap.org/wiki/Tag:barrier%3Dcycle_barrier

However, I would not make these barrier blue as blue means good for bike, but generally it is not that good : you need to slow down or to put your feet down. In best cases, it's simply something you want to ignore.

What about adopting the same strategy as for amenities. An amenity is rendered with full opacity but an access=private|no amenity is rendered with reduced opacity.

We could render barriers with full opacity (hard barriers) when bicycle access is forbidden. We could add them dimmed a bit (reduced opacity / grey instead of black) if they are bicycle=yes or bike-passable (e.g. cycle barrier).

What do you think?

We really must distinguish hard gates closed for bicycles which have a tag access|bicycle=no|private I would colour them for example orange to make them stand out and also visible on a lower zoom level. On a long-distance cycle journey a single closed barrier can mean a long detour.

549 was closed as a duplicate but suggested rendering slaloms and the much more obstructive A-barriers differently, and drawing the gap width above the barrier symbol.

At the moment, cyclosm renders A-barriers with a slalom symbol, which is misleading (and OSM suffers the same bug). A-barriers do not have a width:separation tag, but I am not sure how else they are distinguished.
