[Talk-us] Separate sidewalk vs crossing in the middle of 45 mph road

[Roman Yepishev]

Hello,

As per https://wiki.openstreetmap.org/wiki/Sidewalks#Sidewalk_as_separa
te_way I started mapping the sidewalks that run along the main roads,
but are physically separated from the carriage with more than a curb - 
http://overpass-turbo.eu/s/gKo

Should the highway=* with separate highway=footway/footway=sidewalk be
tagged as sidewalk=no?

Now, routing via Grasshopper and Mapzen will direct you to the road
without a sidewalk just because you want to turn before the crossing
(instead of going a safer route via pedestrian crossing with traffic
signals):

https://graphhopper.com/maps/?point=42.506496%2C-83.42391&point=42.4836
81%2C-83.417076&locale=en-
US&vehicle=foot&weighting=fastest&elevation=true&layer=Omniscale

http://www.openstreetmap.org/directions?engine=mapzen_foot&route=42.505
9%2C-83.4242%3B42.4837%2C-83.4172#map=17/42.49893/-83.41971

The sidewalk "islands" are in the real world as well, forcing you to
seek alternative route through the grass/bushes or cross a 45 mph
street.
