[Talk-us-massachusetts] Crossings

[Alan & Ruth Bragg]

Tagging crossings is a bit confusing for me. The crossing wiki
<http://wiki.openstreetmap.org/wiki/Key:crossing> itself is being cleaned
up.

Previously, I just extend my footway across a highway and tagged the
intersection node as highway=crossing.

Now I'm splitting the footway at either side of the road and tagging the
section crossing the road as highway=footway, footway=crossing and
crossing=uncontrolled,
​unmarked..

Do I still need to tag the node with highway=crossing?

I've been using overpass to see what others are doing.

type:way and highway=footway and footway=crossing in "MA"
​ (3,202 occurrences in MA​


type:node and highway=crossing  in "MA"
​ (​5,295 occurrences in MA)


The wiki page indicates you can put highway=crossing on a way.
​ I don't understand this.​


I don't understand why you would tag a way like this but there are 12 ways
tagged this way in MA.

Joe Holmes offered me this advice:
​"A common problem is sidewalks which go along a street, and the walkers
can cross all the side streets. This is your "crossings" case. The
sidewalks are always highway=footway. It is important that the sidewalks
actually connect to the road to indicate that someone walking or biking on
the road could get on the sidewalk. So I have always been making a
connecting node. I was unaware of the highway=crossing point attribute. I
think you should include that, to document why you are connecting different
types of highways. I will do that in the future. Not if there is actually a
pedestrian bridge or tunnel.

My reading of the use of highway=footway is that there are only three types
of footways, as follows:

1) footway=sidewalk  -- A sidewalk along a street.
2) footway=crossing  -- A pedestrian crossing of a street
3) <no footway= tag>  -- Everything else. Examples are paved entrances into
buildings like schools and churches, and sidewalks not along a street.

So when I see a sidewalk in OSM, I make sure it is marked highway=footway /
footway=sidewalk along the street. And where it crosses a street it is cut
and marked highway=footway / footway=crossing / crossing=xxx. However, I
now see that my crossing values are depreciated. This is changing so fast!​"

​I've been following Jim's method in Bedford.  All of our newer sidewalks
in Bedford have tactile curb cuts so I'll be adding  kerb=flush and
tactile_paving=yes and wheelchair=yes to nodes at either side of the street.
