Can you point to an example, please? consider a u-turn on a motorway with a no u-turn sign posted and maybe an emergency vehicles only sign. you need a no u-turn restriction, but the connecting segment of road is typically a way with 2 nodes (one node on each of the motorway ways.) so you 1) split each of the motorway ways at this node, and set up 2 no u-turn restrictions, with the via element being the short 2-node way between the motorway ways. Okay, that makes sense. you could use this elsewhere, although i think for your example it's not really necessary, an only-left-turn restriction where the left leg of Riva meets West is probably sufficient. I went in and made changes that appear, according to GraphHopper, to route correctly now.

[Talk-us] Turns on bidirectional highways
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 I've been searching for some documentation to explain an intersection that has several turn restrictions that need to be mapped for routing to work properly. The intersection in question is where Riva Road intersects with West Street[0]. Traffic flowing towards West Street need to make an early decision (at the first split) as to whether they are going left or right at West Road. I've been able to add turn restrictions on the right-most intersection showing two lanes turning only right. I'm trying to figure out how to show the bottom intersection but with it being bidirectional I'm not sure how to do so. Any help?

Any help? i don't clearly understand what restriction is troubling you, but be aware that 1) there's no problem splitting ways if it facilitates adding a turn restriction 2) you have some latitude as to how you place the restriction as routers will have some look ahead. placing a left turn restriction on the left side where Riva meets West may be sufficient guidance for routers 3) you can use a way as a via, not just a node. richard signature.asc Description: OpenPGP digital signature ___ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
