From the better late than never department:
I just discovered a description of how Inrix work with speeds to assist
with predicted journey times.
Inrix are a leading supplier of this kind of information to
organisations such as ITIS (in the UK) and TomTom, so I think they have

I wouldn't use 'average speed' for the tag, because it implies something
else, but that's what the OP chose for this thread. 'traffic speed' or
something like that would be better.
I'm not a native speaker, so any improvement on the tag

'time to destination' totally incorrect, the route chosen is often wrong as
well, because choosing a slightly different route would make journey times
much quicker.
but only if not all of the drivers are using OSM i.E. the same shortcuts...
cheers,

Let's start by splitting out static characteristics from dynamic influences

and whatever) is in there, something like TMC information can be used to add
We definitely need an average speed tag, to improve routing.
In my area the road speeds vary a lot depending on the amount of
traffic, which means that the fastest routes selected by routing
algorithms are often not good because the journey goes along roads
where the traffic is nearly

I very much disagree that this should be a tag. If it's going to be
included, it should be in a separate table or set of tables.

Well, where I live (Germany) we have a legal limit of 100 kph on roads
outside of cities, motorways excluded. This legally applies even to
small roads if there is no sign

would be much, much better than nothing. Right now when I make a
routable map for a Garmin GPS I can set the road_class and road_speed
only by looking at the Highway=* tag. This can lead to strange speed
estimates. I think a simple typical speed
