If I may correct your suggestion, that’s not quite right.

 

To quote the wiki for lanes:

 

The lanes=* key should be used to specify the total number of marked  <http://en.wikipedia.org/wiki/en:lanes>  lanesof a road.

The following lanes should be included:

*         General purpose   <http://en.wikipedia.org/wiki/Lane> traffic lanes suitable for vehicles wider than a motorbike.

*           <http://en.wikipedia.org/wiki/Bus_lane> Bus lanes, that are reserved for public service vehicles (PSV), for example buses and taxis. Additionally to the total number of lanes, consider to tag the number of lanes for PSV with lanes:psv=*, lanes:bus=* and lanes:taxi=*.

*           <http://en.wikipedia.org/wiki/High-occupancy_vehicle_lane> High-occupancy vehicle lanes (sometimes also called carpool lanes, commuter lanes, express lanes, transit lanes). The number of such lanes could be tagged using lanes:hov=*.

*         Other lanes such as  <http://en.wikipedia.org/wiki/nl:Spitsstrook>  spitsstroken(nl) in the Netherlands or  <http://en.wikipedia.org/wiki/de:Stra%C3%9Fenquerschnitt#Seitenstreifen>  temporäre Standstreifen(de) in Austria, Germany and Switzerland which are available to traffic at certain restricted times, for example during the rush hour.

*         Longer slip-roads, for example on motorways and other fast major roads. Turning lanes for minor roads are not normally included. See  <https://wiki.openstreetmap.org/wiki/Key:turn> turn=* for further details about tagging turning lanes.

And the following lanes should be excluded:

*         Minor slip roads without a deceleration/acceleration lane, i.e. the main road is wider only because of the intersecting road.

*         Parking lanes. Consider using  <https://wiki.openstreetmap.org/wiki/Key:parking:lane> parking:lane=* to provide further information.

*         Bicycle lanes. Use the tag  <https://wiki.openstreetmap.org/wiki/Key:cycleway> cycleway= <https://wiki.openstreetmap.org/wiki/Tag:cycleway%3Dlane> lane for those.

*         Emergency   <http://en.wikipedia.org/wiki/Shoulder_(road)> shoulder lanes. See  <https://wiki.openstreetmap.org/wiki/Key:shoulder> shoulder=* for further details.

 

So a “normal” two way road with cycleways (in Australia, with left hand traffic) would be tagged as:

 

cycleway=lane

lanes=2

vehicles:lanes:forward=no|yes

vehicles:lanes:backward=no|yes

bicycle:lanes:forward=designated|yes

bicycle:lanes:backward=designated|yes

 

When tagging to this level, I generally try to also add the width:

 

width:lanes:forward=1|3

width:lanes:backward=1|3

 

in JOSM the “lane and road attributes” mapstyle will help visualizing these tagged lanes.

 

Use vehicle instead of motor_vehicle (to keep carriages out of your cycle lanes…).

 

Important: Do NOT include the cycleway lanes in the lanes=x count! The lanes count (which only counts marked lanes for motorized traffic) and the number of entries in the :lanes prefix keys can and will be different! (Which is maybe somewhat unfortunate, but the lanes=count tag predates the :lanes prefix tags by many years, and has been used that way all over the place. Mixing different definitions of the lanes key in different places, or even just different segments of the same road, is going to result in useless, unreliable data as a data consumer will have no way to differentiate what definition of lanes=count would apply.)

 

See https://wiki.openstreetmap.org/wiki/Lanes#Crossing_with_a_designated_lane_for_bicycles for an example of that.

My suggestion:

 

cycleway=lane

lanes=4

lanes:forward=2

lanes:backward=2

motor_vehicle:lanes:forward=yes|no

motor_vehicle:lanes:backward=yes|no

bicycle:lanes:forward=yes|designated (maybe no|designated if you're not allowed out of the bike lane on a bike)

bicycle:lanes:backward=yes|designated

 

 

 

 

 

 

Rationale for this:  Sometimes things get complicated.  For example, how would you smash the following tag scenario into "don't include bike lanes in the lane count" schemes?

 

cycleway=lane

oneway=yes

lanes=5

turn:lanes=left;through|left;through|through|through|right

bicycle:lanes=designated|yes|yes|designated|yes

motor_vehicle:lanes=no|yes|yes|no|yes

 

And sometimes the cycleway=* tag just can't deal with the situation at all, like when you have curbside bike lanes and the rest of the lanes are shared.

 

access:lanes:backward=yes|yes|no

access:lanes:forward=yes|yes|no

bicycle:lanes:backward=designated|designated|designated

bicycle:lanes:forward=designated|designated|designated

cycleway=lane

highway=tertiary

lanes:backward=3

lanes:forward=3

lanes=6

name=South Greenwood Avenue

turn:lanes:backward=left;through|through|through

turn:lanes:forward=left;through|through|through

I want to tag a road (one of thousands in this country) that has two lanes for cars  (one in each direction) and two cycle lanes, one on each side. Thes cycle lanes are by law one-way in the same direction of the motorized traffic in the neighbouring road lane.

My (basic) tagging would be:

highway=unclassified (or whatever)

cycleway:right=lane

cycleway:right:oneway=yes

cycleway:left=lane

cycleway:left:oneway=-1

the value "-1" is discouraged for the "oneway" key, but in this case I see no alternative
"cycleway:left:oneway=-1" has some 800 uses in taginfo, "cycleway:right:oneway=yes" has some 2800 uses in taginfo.

Should I go ahead with my tagging? Alternatives?
