Wrong exit number in a roundabout if a waypoint is inside
Oliv opened this issue · comments
Describe the bug
When a waypoint is inside a roundabout, there are 2 main problems :
- The instruction
At roundabout, take exit X onto ...is on the waypoint coordinates, and not on the roundabout entrance - The exit count is wrong, since it counts starting from the waypoint and not the roundabout entrance
To Reproduce
Put a waypoint on a roundabout
Expected behavior
I think there are two possible behaviours:
- Make an exception for the use case where a waypoint is inside a roundabout
- Introduce the concept of "silent waypoints". Waypoints could be flagged a silent, and then would be used only for routing, and not for instructions
What are your thoughts on this ?

No idea if this simplifies something, but IMO before fixing this issue we should first introduce an extra instruction for "leaving the roundabout": #1787
Hello again,
what is the status on this bug ? This is quite an issue for us since in bike / car profile we have quite a lot of wrong instructions.
Please let me know if you don't plan to have a look at this issue, and I'll try to fix it myself.
Regards, Olivier
I don't think anyone is working on it right now.
