Freeway tag

Posted under Tags

I've been updating some posts to include a new tag named freeway, which is distinct from a regular highway by its number of lanes per direction and the barriers dividing them. However, it appears that the most appropriate name for this tag is expressway, which is actually used in Japan, and freeway is a US term that might not be appropriate here.

By Japan's definitions, they consider these roads as:

  • Expressway for freeway (multiple lanes per direction).
  • National roads for regular highway (one road, two different directions).
  • Some prefectural roads are considered highway, but some aren't.

A lot of terms are used interchangeably and vary by country and even regions within a country. This is why in most cases we should use US terms/meanings where possible for consistency. In this case, there is nothing wrong with the term freeway or expressway in the manner that you wish to use it. As far as common usage and even the US government definition goes, both terms will fit your intended definition with only a minor difference of degree of access being the primary difference if there is any.

The US Federal government defines them this way:

  • Expressway: A divided highway facility with partial control of access and two or more lanes for the exclusive use of through traffic in each direction; includes grade separations at most major intersections.
  • Freeway: A divided highway facility with full control of access and two or more lanes for the exclusive use of through traffic in each direction.

In short: Expressway = limited-access, Freeway = controlled-access.

Wikipedia currently defines them this way:

Definitions

Controlled-Access Highway – Designed exclusively for high-speed, unhindered vehicular traffic, with no traffic signals, intersections, or property access. These highways are free of any at-grade crossings with other roads or railroads, which instead use overpasses and underpasses to cross the highway. Entrance and exit to the highway is provided by ramps at interchanges. Opposing directions of travel are usually (but not always) separated by a median or some sort of traffic barrier. Generally, pedestrians, non-motorized vehicles and farm machinery are not allowed on these types of highways, although some exceptions do exist in certain areas

Limited-Access Highway – A highway or arterial road for high-speed traffic which has many characteristics of a Controlled-Access highway (see above), including limited or no access to adjacent property, some degree of separation of opposing traffic flow, the use of grade-separated interchanges to some extent, and few or no intersecting roadways. Unlike Controlled-Access highways, pedestrians, non-motorized vehicles (e.g. bicycles), and farm machinery are not explicitly prohibited (although exceptions may exist). [...]

Freeway – In official use, a Freeway is the same as a Controlled-Access Highway. [...]

Expressway – In official use, an Expressway is the same as a Limited-Access Highway. [...]

I'm personally really not a fan of adhering to the US terms.

While I can't speak for everyone, at least in my own slice of not-the-US, when someone mentions "freeway" they're not just talking about controlled-access highways, they're talking specifically about the US freeways. Generally "highway" is used to refer to general high-speed motorways (as per the secondary definition listed on Wikipedia: Highway). However, because of the two different definitions, using this as the main tag name seems problematic and should probably be avoided.

For this reason I think "expressway" would be better (with utility aliases from freeway and other related terms), as it's still commonly recognized as meaning the same thing, plus it has the benefit of recognizing that we're still mainly dealing with Japanese artworks, where the in terms of access control there's basically just expressways and everything else (see asset #23179963 for an example of how non-access-controlled all but the expressways are).

I know it's not unprecedented that we stick to US-centric names/concepts for consistency and simplicity, but given the rather stark contrast between US, JP and rest of the world roads, I think it's better to construct a somewhat neutral approach.

I feel like highway deserves a bit more consideration, since if we apply it based on it's real definition it'd just turn into a synonym for road.

I guess getting rid of the images with sidewalks and buildings from the tag?

Basically, the real-world definition is:

A highway is any public or private road or other public way on land. It includes not just major roads, but also other public roads and rights of way.

That means it's.... basically everything? Using the tag for that doesn't seem very useful to me, and then there's the issue where some people are used to using "highway" to refer to what tis BUR would be calling expressways exclusively. Maybe someone has a better idea, but I'm not entirely sure what would be a good course of action with this tag.

Thinking this over more, I see no point in this tag, as it's essentially what we're trying to use highway tag for to begin with. If you look at the images under Wikipedia there isn't a single image of minor roads and everything you're apparently trying to call an expressway.
