Hello,
I was fixing incorrect restrictions tagging in the area, when I noticed restriction=no_u_turn on the
highway segments forming the roundabout (not talking about the junctions with the roundabout, but
really the roundabout itself). [1]
Indeed the restriction is about u-turning onto the identical road segment. This
makes no sense.
I find strange to tag the segments of the roundabout with no_u_turn because the roundabout and the
entry/exits junctions are tagged oneway (and you're not supposed to make a u turn in a oneway).
junction=roundabout is considered implicitly to be a oneway. Some people prefer to add an explicit
oneway=yes which would do no harm.
Am I missing something ?
No.
Shall I remove these restrictions ?
Yes, and contact the mapper via changeset discussion. Ask him/her what the intent was behind the
restriction. Sometimes people try to fix the behaviour of a particular satnav system, while in this
case the issue would need to be filed with the satnav software.
Thx.
