Support for OSM noexit tag

[zcc@…]

Routes should not pass via dead ends

[anonymous]

I dont want to call this useless, but a dead end is always defined by physical conditions (road ends or continues as a cycleway/footway) or legal ones (road becomes oneway street...) that are mostly already covered by navit.

I would rather like to see support for the OSM barrier tags, like barrier:bollard. Many streets are divided in the middle by barriers that only let bicycles and pedestrians pass, but not cars.

It would be cool to have these tags split the (car-)routing graph at such nodes and maybe show a symbol on in the map view. :-)

Please provide a node or way id where this tag is used

I'm not the original poster, but i believe that this feature is required. Examples:

way_42323075 and way_42323104 represent same street, but this street is physically divided by barrier (node_528206252)

Same thing is on the near by street (way_41768680 way_42376985 node_514753526)

You can look to this area at  http://www.openstreetmap.org/?lat=54.7215&lon=20.4935&zoom=17&layers=B000FTF

Another one example is way_42348290 and node_528656485 This street is connected to way_19754089 but there a fence, that doesn't allows cars to pass, only pedestrians are allowed.

The noexit tag is either redundant (if you have to look at the barrier node also) or not sufficient (it doesn't tell which side of the way has no exit).

Ok, I am putting implementing support for barriers to my todo list. But the fence example most likely won't work even if navit supports the barriers. You need to split the way at the barrier then.

Looks reasonable. Anyway, may be it would be useful, if roads with such tags will be rendered/marked as deadends?

Ok, thank you! But why the fence will not work? It's a barrier, like a barrier=bollard etc
