Re: [mkgmap-dev] question about ignored no_u_turn restriction

Hi Chris, many Garmin devices do have an option "avoid u-turns / Ausschluss

Kehrtwenden".

So I guess this kind of turn restriction is for the Garmin routing algorithm a complete other thing as "normal" turn-restrictions.

I think the 'avoid u-turns' option tells the device to only do u-turns when it's the only choice - effectively a 'no u-turn' restriction at every intersection. I assume that the routing algorithm follows the actual turn restrictions when the 'avoid u-turns' option is disabled. But as Gerd pointed out, he's not sure if the no u-turn restriction in my example actually has an effect so my assumption could be wrong. Thanks, Ben
