Re: [mkgmap-dev] vehicles in restriction relations

Hi Paco,

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 ? AFAIK the img format doesn't contain any kind of traffic light. I think this is not needed, as it only influences the avg. speed.

BTW: In Germany we have a green arrow which allows right turn after stopping and giving way. It is often misunderstood to be something like a "ignore red light" sign. Gerd
