Clarifications for an American

It seems like motorroad=yes generally indicates that the road is designed for high-speed travel, offers no direct access to adjacent properties, and may or may not have at-grade intersections with other public roads. Is that correct? American engineers and roadgeeks would tend to call such a road an "expressway". Vid the Kid 20:29, 16 July 2010 (UTC)

No - access in the expressway sense refers to driveway access, while access in the motorroad sense refers to cyclist/pedestrian access. --NE2 13:29, 25 October 2011 (BST)

I have a hard time understanding how/why this key should be used in the context of roads in the US. Motorways, Trunks, and Primaries already do a decent job (at least according to classifications used in civil planning) for what appear to be the types of roads being described. Adding the necessary access specifications to any of those makes more sense to me organizationally than a whole separate keyspace (with only one value).

Existing usage is almost all in Europe, India, and Japan, and in combination with highway=*, with 80% yes and 20% no values. For all I know, it may have pre-dated the access concept. I worry that usage elsewhere (especially without highway=*) might be from mappers who didn't grok highway=* . AM909 00:55, 14 December 2011 (UTC)

"Access concept" predates this for certain; that doesn't mean tagging motorroads with this tag wouldn't be valuable. A motorroad is always signposted as such, with the distinct traffic sign, and can have special implications that might not be relevant for ordinary car routing. Many other high volume roads can have a different traffic sign "no bikes or pedestrians", but without any of the visual and functional characteristics of a typical motorroad. Here we have quite few motorroad sections, but I believe they're more common in Central Europe. Motorroad=yes without a highway tag must be a mapper's error. Alv 08:10, 14 December 2011 (UTC)
Motorroad is useful where the government has defined a specific class between trunk and motorway. It's really not useful otherwise (e.g. the U.S.). --NE2 18:50, 14 December 2011 (UTC)

France

The page currently states that all Trunk Roads in France are automatically motorroads - surely this is incorrect! Many all-purpose roads have green destination signs (and therefore mapped as Trunk in OSM) but only some Trunk routes in France have the 'car on a blue square' sign indicating motorroad restrictions... unless I'm missing something. Can anybody help on this one?--CunningPlan What's on your mind? 14:35, 6 August 2014 (UTC)

In France the use of the C107 sign is reserved for "Voie Express". These roads are regulated and involves a ban for slow vehicle (motorcycle, pedestrian, ..)=> Trunk. They are often limited to 110 KM / h. Warning: some roads are limited to 110km / h but are not "Voie Express" and slow vehicle are allowed => Primary and maxspeed=110
