I think that only these informations could help us to choose the good way to set our french roads.

Penalties

General definition

The penalty system, is responsible to find the fastest route, it eliminate possible routes giving them more time than expected.
As the word says it by itself, the penalty system, will give negative score to segments that could interfere in our route.
The Estimated time of arrival will be increased by the "penalty system" if moving from segment to segment is not recommended.

Type of penalties

Road type: non drivable roads, such as Boardwalk, Runway, Railroad equal a 1 hour increase to the ETA.
((need more road type penalties here, parking lot road, private road, service road and such))

Toll roads: If "Avoid toll roads" was set on the client, it will multiply the penalty, otherwise it will be considered a regular road.

Sharp angled turns: Such as "U" turns adds an infinite amount of time to the ETA. A penalty will also be given to "U" turns made out of three segments. In some places, if the length of the middle segment (connecting the two larger ones) is larger than 15 meters it wont grant a penalty.



Road direction:
Direction not set : +0.30 seconds to the ETA (in the U.S and countries with basemaps).
Direction not set with drives in the opposite direction only: For every drive recorded in the opposite direction it will be a 30 seconds penalty to the ETA.

Minimum turns selected in the client: The system will add 1 minuet to the ETA for every turn.

Long Distances:
0-15 km - All road types are allows for routing.
15-20 km - All road types except Streets.
20-30 km - All road types except Streets and Primary streets.
30-200 km - Only Minor, Major, and Freeways.
more than 200 km - only Freeways.

Or do you also have voie express roads without a number?

Long story.

Indeed, I know what Mycrophage mean. And indeed, Mycrophage know what I mean.

Freeway have very strict classification rules : http://www.waze.com/wiki/index.php/Map_Legend#Freeway

If all these criteria are present, then it is Freeway. As simple as that.

Some "Voie express" are Freeway, some other are not because they don't meet all the criteria.
What Mycrophage propose is to set all the Voie Express as Major because they are not 'Autoroute'. Of course they are not 'Autoroute', but they are Freeway not Major.

Thx for you're attention.
The main reason why "voies express" shouldn't be freeways to my mind is their function.
Autoroutes are for long distances.
Voies expresses are mostly for medium distances or shorts with heavy trafic.
They can have ramps or roundabout.
I do not said that Voie Express have to be the only road to set in the Major Highway category.

Autoroute, routes nationales, routes départementales.

This is non useable.
Look at the difference between the D980 (near Toulouse) and the D234 (in the french alps near Briançon)

Deparemental: Minor highway

There is an historical thing to know in France: The "Routes Nationales" will become "Routes Départementales" because of some new administrative rules. The government gave (and is giving, and will continue to give) the maintenance of those big roads to the "départements" instead of managing them itself. Those new "Routes Départementales" are often the D9xx, they were the N1xx before the "Nationale" to "Départementale" change. All the "Routes Nationales" are concerned, a day or another.

So, when a "Route Nationale" will be changed to a "Route Départementale", we should change it from Major Highway to Minor Highway? This is all but a functionnal map.

After, every "Route Départementale" is not a big road. Some should not be more than a Primary Street, but they are called "D6" for example ("Route Départementale 6").

Basing the map on the name and on the numbers is not the right way in my opinion.

We must find the way to sort the roads, a way which is not the name and not the physical aspect.

There is a map which give the "Routes à Grande Circulation" (RGC), an administrative status given by the government stated on the function of the road in a local environment. Those roads are sometime "Nationales", sometimes "Départementales" and another times "Autoroute". They are sometimes like freeways, sometimes like "voies express", and the most times like every simple road: one two-ways road. We gave in the past an idea to use this RGC map to make the dinstinction between Minor Highways and Majors Highways with the roads in blue may be Freeways, the ones in red may be Major Highways and the others in grey would be Minor Highways.

Please, excuse my bad english

You can also have a look on this Map : Raster
The Map "Raster" use the same color and the same Road labeling.

Il faut juste les classer par aspect .
