OpenStreetMap
There's a road near here (Hampden Road) with the usual Evel Knievel sign at its start (it's a cul-de-sac). The sign is qualified with the equally usual "Except for Access".
It is shewn in OSM as access=destination; bicycle=yes; highway=residential
Where does access=destination come from ? Is it a made-up value ? (Not that there's anything wrong in that)
Thing is, access=private, access=permissive and so forth, refer to all classes of traffic whereas, here, it seems to refer just to motor traffic. Which is correct
I would have put the "destination" bit as motorcar=destination | motorcycle=destination and left everything else as defaults (access=public being assumed)

The destination value is documented here: access=*
In my opinion, access=destination is not the best choice here, it should indeed be =destination.

Sorry, this was supposed to read: ... it should indeed be *insert_vehicle_class*=destination

Please, don't use motorcar and motorcycle if you want to adopt it for all vehicles. See the access page for the classification: osm.wiki/Access#Land-based_transportation
So in your case, I guess it should be motor_vehicle=destination.
On the other hand, most people think that destination-only access implies that pedestrians and bikes are allowed because they don't travel large distances (except for some racers). I don't know if that's right, but I know that no policeman would stop a bicycle because he's in a access=destination street. So I believe that allowing bikes and pedestrians in access=destination areas is OK.

Thank you, Tordanik and Sanderd17.
I will indeed use motor_vehicle=destination
In this particular street, there is nowhere for bicycles to go (the only exits are cycle-prohibited footways). This doesn't stop a persun physically picking up a bicycle though as (in the UK), it ceases to be a vehicle. This is the same if you just wheel a bicycle (but I know this isn't true in other countries)
Anyway, irrespective of what a Police persun would be likely to do, I would like the tags to match the actual road signs. In this case, it says "No MOTOR Vehicles"; there is a "No Vehicles" sign (which no-one ever understands because it's just a white disk with a red border). I've never seen one of the latter qualified with "Except for Access", but such a Traffic Regulation Order could exist.

access=yes is public access. access=destination means you can't go there by any mode unless it's the only way to your destination.
