[OSM-talk] Turn left restriction on two way highways
Hi, In Argentina we have a general rule. If you are driving in a two way highway (residential, primary, secondary, etc) you can't turn left. You can do it only if there is a sign and/or traffic light with the turn left row. We are discussing in the Argentina forum about if it's make sense to map the no_turn_left restriction on every crossing road or not. I think that we should drive the exception to the rule, the routing software should apply the default restriction. What are you doing in the other countries?

Re: [OSM-talk] Turn left restriction on two way highways
I'm reading the law again and it's a little confusing. It says "you can't turn left on ways with traffic lights". I'm discussing about this in the Argentinian OSM forum.

I reviewed the local law and sometimes you can turn left so we must tag the restriction on every case.

[OSM-talk] Cost of tolls
Hi, Mapping the tolls of a highway a found that there is no tag to assign the cost of the toll. I haven't found examples in taginfo or tagwatch. Are you using something for this? I know this is a little complex because the cost of the toll is different and depends in the size of the vehicle, the time of the day, etc. but may be we could do something.

That schema works in Argentina I think, and may be in other countries. I posted it to hear opinions about it.
