But what about when both are present?

In the US, we have the situation where on ramps (link roads, slip roads)
the regulatory white sign will be the one from the highway (often 65 mph) and
then there will be an advisory yellow sign saying something lower,
sometimes as low as 20 mph.

Then there is maxspeed:typical.

So it seems that it should use the first of

  maxspeed:typical
  maxspeed:advisory
  maxspeed

that is present, but it sounds like you are saying that osmand only
uses maxspeed:advisory when plain maxspeed is missing.


The real question for routing is "at what speed can we expect that a
reasonable driver will traverse whis segment".  That's why I put typical
first.  There is a ramp near me where (reality, not sure of todays'
tagging)

  maxspeed:typical=  40 mph
  maspeeed:advisory= 20 mph
  maxspeed=          65 mph

I realize it varies from country to country, but in many parts of the US
the relationship between regulation and reality is quite off.  Having
driven in the UK, I can realize how this would seem very strange to UK
drivers who have not experienced the US outside of large cities.
