Hi Marco,

...

Mark, may I suggest a totally different approach?

why not to use a couple of restriction relations?

a no_straight_on between the segment before (from) and after (to) the bollard node (via) and a second no_straight_on relation the way round.

Of course with the right "except": bicycle, foot, ...

You could also invent an "internal" relation restriction like "no_passage"

The issue here seems that the "except" key does not foresees "foot".

Would it be feasible?

I don't think so because turn restrictions affect all traffic except foot so you could not distinguish between a car and a bicycle.

Mark, the wiki page about restrictions http://wiki.openstreetmap.org/wiki/Relation:restriction says I can put a key except with the following values/meaning: except - psv/bicycle/hgv/motorcar - The restriction does not apply to these vehicle types (more than one: except=bicycle;psv) So do you mean that mkgmap does not actually support/handle the except key in a relation restriction? Ciao, Marco.

Cheers,

Mark _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
