Why not ask your question on the new OpenStreetMap Community Forum?

When tagging a way with shared lanes for bicycles in both directions there are three ways of doing to my understanding:

  1. cycleway:both=shared_lane
  2. cycleway=shared_lane
  3. cycleway:left=shared_lane and cycleway:right=shared_lane

Which is the most appropriate one? 1) is the most compact and has no ambiguities, but some tools (including JOSM) do not render it. 2) is also compact, but does not explicitly state that there are two ways. 3) has no problems but requires two keys.

The Bicycle page does not list a preferred tagging for type L1a, which is similar to your case (though not shared). I typically use (2). Since all three are equivalent and all data consumers should threat them the same, why bother typing extra characters to convey the same. Yes, I am lazy.
