Hm, I would think that a restriction-type relation would necessarily restrict what's possible, whereas a two-stage turn box gives more possibilities rather than takes away possibilities (at least in cases where it's not mandatory). However: Does the French sign mean that the cyclist is not required to obey a red light but instead is only required to yield? If yes, then that's similar to the two-stage turn box (it gives more possibilities rather than restricts), and if that's already established, I'll be happy to go along with a similar scheme. > > - optionally segregated=yes if there is a designated, separated > > waiting area for the bikes rather than only a painted area that is > > also driven over by other vehicles (would usually be at particularly > > wide intersections or at T-intersections) > I disagree, today the use of segregated key is for path where the segregation > is made from painting line. https://wiki.openstreetmap.org/wiki/Key:segregated > If we use the key segrageted for physically segragation by kerb or island > that can lead easily to mistakes. > May be use waiting_area=painting_box if there is only painting, and > waiting_area=track ? island ? if it is physically protected. Ah right, then let's not use segregated. If there is no better existing tag to reuse, a waiting_area=painted_box and waiting_area=track seem good to me. Or to match values in https://wiki.openstreetmap.org/wiki/Key:cycleway#Dedicated_cycle_lanes how about waiting_area=advisory and waiting_area=exclusive? > I think it can be interessting to know if the two stage turn is mandatory or > not for the cyclist, I’m not talking about national law here but only if > there is a traffic sign saying this obligation. > mandatory=yes ? Yeah, that could work. `mandatory` is already in use on the Key:cycleway wiki page as linked above, so using it as mandatory=yes could work (if indeed there is such an obligation somewhere).
