The road is labelled RA6 on the map, but not on the physical road. The
exit I should have taken had no mention of RA6, nor did the road
itself (when I finally found it) have any RA6 sign. RA6 may be a
formal name which exists on some piece of paper in Rome and Brussels,
but it is not a name used on the highway. The AA route planner
describes the correct exit much better.

Nor on the graphic, they provide of the sign you have to follow.

Are you saying that the sign Via Michelin depicts in a graphic is wrong?
I googled and found Italian sites referring to RA6. Others must be aware of RA6.

Re: Accuracy of route planners
The formula I use, that I find consistently accurate, is to divide the
distance by 70kph.
In every single route? Routes where 70% of the road is autobahn?
Routes through mountain passes where you can't drive 70? I don't think
so...

Re: Accuracy of route planners
Found this site:
http://www.tcs.ch/main/de/home/verke...enzustand.html
It shows the actual traffic situation in Switzerland, including
autobahns and the most important roads.
There aren't too many jams. However, one 3 km "stau" in St. Gotthard
tunnel. Surprise, surprise...
Check this out: http://tinyurl.com/34682f
Photo: http://www.gotthard-strassentunnel.ch/aircamgr.htm
It's quite easy to calculate the realistic driving times if you know
where the jams usually are. Putting extra 30-45 minutes passing St.
Gotthard isn't exaggerated.
Cheers.

Actually, I looked at it again, and I see that it was much more
explicit than just "RA6". The exits were popping up fast and furious,
and maybe I didn't look at the itinerary carefully enough. I was also
contending with a backseat driver who had his own ideas about what
route we should follow, and whom my husband occasionally obeyed, with
unpredictable results.
>I googled and found Italian sites referring to RA6. Others must be aware of RA6.
I can say with absolute certainty that the road is not signed as RA6.
The only sign identifying it called it the Raccordo Perugia-A1. There
were four of us looking for a sign with RA6, both before we found the
road and after we were on it, and no one saw any such sign.

I can say absolutely that I never said it was. :-)
What I said is that Italian websites refer to RA6. We have a similar problem
with Dutch A motorway notation and EU references to E routes.

We had a similar problem near Pisa a few years ago. I was trying to
find a limited access highway I saw on the map but didn't know what it
was called. I later learned it was called the PIFI something or other
(three city abbreviations all ending in "I", two of which were Pisa
and Firenze.)

Re: Accuracy of route planners
Following up to [email protected] :
> Rest is windy road where the speed is quite low, I suppose.
Max 80km/h (national speed limit), and on average in the mountains I reckon
on getting around 40-50km/h. That's on a fast-ish bike.

Yes. Try it. I've just returned from a 2,532.1 mile trip, 2,101.7 on
the Road that included high-speed freeways and two-lane roads,
two-lane mountain roads, some gravel roads, and two national parks.
The highest-speed leg was 63.9mph, the lowest 19.7mph. The trip's
average speed was 46.2mph. A detailed chart will be posted in the
"Travel" section at the site at right in the sig within a month or so
under a subject similar to "The Road: June/July 2007" that already
exists at rec.travel.usa-canada.
The formula I incorrectly converted for your convenience is distance
in miles divided by 50mph. So the trip should have taken 42.2 hours.
It actually took 44.1 hours, a difference of about six percent. Big
deal.
