Hi Minko, Hi Gerd,

You're reminding me of a question I've got for mkgmap developers.

I'd like to know if the right turn on red
(https://en.wikipedia.org/wiki/Right_turn_on_red) is taken into account by
Garmin in their map format and routing algorithm. I guess yes because Garmin is
US-based, where this kind of traffic light is widespread and that it allows for
faster right turns.

Has anyone ever succeeded in reverse-engineering it in the map file format ?

It'd be great because we recently got a new sign in France allowing cyclists to
turn right on red after yielding to crossing pedestrians.
(https://en.wikipedia.org/wiki/File:Turn_right_on_red.JPG).
In OSM, it's tagged with :
type=restriction
restriction:bicycle=give_way

Thanks,

Paco
