Hello, I have a question regarding correct tags on a road with conditional access to motor vehicles with an exception for buses, motorcycles, mopeds, mofas. Specifically, I am not sure Grafton Bridge, Auckland, New Zealand (36°51'33.4"S 174°45'54.1"E) has correct tagging.

Grafton Bridge:

  • 1 lane in each direction

  • condition - 7am-7pm, Mo-Fr - Bus Lane (access to buses, motorcycles, mopeds, mofas, psv) (Bus lane access description)

Current tags are following:

bicycle=yes 
bridge=yes
bus:lanes:backward=designated
bus:lanes:forward=designated 
foot=yes
highway=secondary 
lanes=2 
layer=1
maxspeed=30 
maxweight=44
motor_vehicle:conditional=no @ (Mo-Fr 07:00-19:00) 
motorcycle=yes
name=Grafton Bridge 
name:ja=グラフトン橋
psv=yes 
surface=asphalt

Question: Now, doesn't the bus:lanes occupy all the lanes and prevent all other vehicles from access? I would see the tags rather as following:

bicycle=yes 
bridge=yes
bus:lanes:backward=designated @ (Mo-Fr 07:00-19:00)
bus:lanes:forward=designated @ (Mo-Fr 07:00-19:00)
cycleway=share_busway
? Exception for motorcycles ?
foot=yes
highway=secondary 
lanes=2 
layer=1
maxspeed=30 
maxweight=44
name=Grafton Bridge 
name:ja=グラフトン橋
surface=asphalt

Or

bicycle=yes 
bridge=yes
foot=yes
highway=secondary 
lanes=2 
layer=1
maxspeed=30 
maxweight=44
motor_vehicle:conditional=no @ (Mo-Fr 07:00-19:00) 
motorcycle=yes
bus=yes
moped=yes
mofa=yes
name=Grafton Bridge 
name:ja=グラフトン橋
psv=yes 
surface=asphalt

Do I understand right that when there is a tag with a sub-group (motorcycle) of motor_vehicle, and without conditions, it excludes these from the motor_vehicle conditions?

Thanks a lot!

There is only one lane per direction and the same restrictions apply to both directions. So there is no need for any :lanes tagging. bicycle=yes, foot=yes etc. don't need to be tagged as they are default for a highway=secondary.

Your last question is a bit tricky and interpretation of conditions might be implemented differently by data consumers. To be on the safe side I would explicitly tag what might be confusing.

I'd propose:

highway=secondary  
name=Grafton Bridge  
name:ja=グラフトン橋  
bridge=yes  
lanes=2  
layer=1  
maxspeed=30  
maxweight=44  
surface=asphalt  
sidewalk=both  
motor_vehicle:conditional=no @ (Mo-Fr 07:00-19:00)  
motorcycle:conditional=yes@ (Mo-Fr 07:00-19:00)  
bus:conditional=yes @ (Mo-Fr 07:00-19:00) (or psv?)  
moped:conditional=yes @ (Mo-Fr 07:00-19:00)  
mofa:conditional=yes @ (Mo-Fr 07:00-19:00)

That is what I thought, thank you. I do not really understand why there was originally "bus:lanes:backward=designated..." as for one lane in each direction, it would occupy all lanes. These Bus Lanes in New Zealand are not the best for OSM tagging :D

Thank you, I agree...
