Hi Liu IMO you should solve this with relations.
1st relation: type=route route=road ref= 19A 2nd relation: type=route route=road ref= 172 then you just need to add the ways/nodes to the according relation (and please avoid overlapping ways). voila :) Greets Mario Louis Liu schrieb: > Hi: > > How do I tag highway section that shared by two or more highways? > > This is an example: > http://p2.p.pixnet.net/albums/userpics/2/2/32022/1207242904.jpg > The road sign presents the way section is highway 19A (省道臺十九甲線) and > also highway 172 (172 縣道). > The situation is common in Taiwan. > > In cording http://wiki.openstreetmap.org/index.php/Tw:Taiwan_road_tagging, > highway 19A is tagged as "highway=primary" > and highway 172 is tagged as "highway="secondary". > > So, how can we tag it? > > The relation between the two highway: > > > | > |19A > | > --------------========================------------------ > 172 19A & 172 | 172 > | > |19A > | > _______________________________________________ > talk mailing list > [email protected] > http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk > _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
