import bus lane restrictions from OSM

[ambuehll]

It seems as if dedicated bus lanes allow private vehicles. OSM has some tags which would allow identifying such lanes and reducing the number of lanes accessible to cars. I guess the OSM tagging not really unified.
Nonetheless, there are some tags, e.g:

	<tag k="bus:lanes:forward" v="designated|"/>

	<tag k="psv:lanes:forward" v="yes|"/>

	<tag k="bus:lanes:backward" v="designated|"/>`

which provide information regarding the number of lanes dedicated to cars.

Thanks!

There are three tagging schemes for bus lanes (https://wiki.openstreetmap.org/wiki/Bus_lanes).
Currently, netconvert only supports the busway scheme

also somewhat related to #10650

is fixed now with 40e0519 but needs the option --osm.lane-access

@ambuehll Just one more question concerning the Seilergraben example edge (145204590). It has a trolley wire and a tram edge running parallel (217408202). Is this correct? (Are there rails?)

[ambuehll]

Thanks!
Seilergraben has 4 lanes in total: 2 lanes inbound, 2 lanes outbound. in each direction, there is a lane for cars (the right lane in direction of travel) and one lane for bus and trams. This lane has tram tracks and is used as a bus lane at the same time.
I hope that clarifies things. Essentially, how I see the OSM-tagging in Zurich, it's "psv:lanes" if there is something else than a bus (either a tram or a bus and a tram) and a "bus:lanes" when it's only for buses.

Thanks for the answer, I just could not imagine that you can have a trolley bus and a tram on the same track but my trolley bus experience is very limited ;-).
The way it is currently implemented psv:lanes maps to taxi and bus while bus:lanes maps only to bus. Tram is always imported from the tracks. Are taxis allowed on Zurich's psv and/or bus lanes?

[ambuehll]

ha! good question, the answer is "it depends". so I am not quite sure actually how this is tagged in OSM by the Zurich community.
