Hi Gerd, IMO it should goes like that: - Each duplication of a road should duplicate restrictions. - Any modification of access flags for original or duplicated roads should be performed accordingly on restrictions. - Redundant restrictions should be removed, this can happen because of changes in access flags or when restriction goes wrong-way.
Assume that a via way of an only_left restriction has also an opposite cycleway. Should mkgmap create all possible combinations of restrictions to make sure that also bicycles are only routed left ?
I don't understand this problem. If OSM restriction "only_left_turn" include bicycle, then you should create Garmin restrictions to route bicycles too. I see your next post, will processing of restriction:bicycle solve this question? -- Best regards, Andrzej
