Summary

An example to show Lanes features and caveats at a junction. Note that there is a need to map the shortcut link in the north-east separately, since drivers may skip the traffic light using it. The detail would be lost if it is omitted. This does not work for any other corner, so it is semantically equivalent whether curves are drawn or not.

The style supports offsetting Lanes wrt to the osm way, but if you use a transitional segment, e.g. when road markings are dashed or not present and placement=transition is used, offsetting is unsupported which seems to be an artificial limitation.

Note that a turn restriction is used, to prevent routers sending vehicles coming from the west going north at the single-laned tertiary link. If software properly supports Lanes however, the turn restriction should not be needed as it is deductible by turn:lanes:backward=none used on the primary branch leaving east.
