oneway タグ は、ウェイの通行制限を示すために使われます。 This means that this tag should be used when this way can only be used in one direction.
Take a look on the access=* page to add more detailed restrictions.
マッピング方法
任意の highway=* タグに加えて、oneway=yes タグを追加します。 ウェイの方向と一方通行の方向を合わせるようにしてください。 (JOSM でウェイの方向を見るには、一般あるいはレイヤーの設定で有効にします; Potlatch では、ウェイの方向を表示するための、画面の左下に矢印があります。)
道路の一部分だけが一方通行の場合は、ウェイを複数のウェイに分割する必要があります。
Some tags (such as junction=roundabout, highway=motorway and others) imply oneway=yes. You don't need to add a oneway tag, because they are oneway by default. If a tag implies an oneway value, this is noted on the implying tag's wiki page. There is ongoing discussion about implicit oneways, so applying a tag is not wrong.
If for some reason the oneway goes not in the direction of the way, the fix in most cases is to turn the way around ("reverse way" tool in the editors, JOSM and Potlatch have menu options for this), and apply oneway=yes. もし、ウェイの方向を変えられないという希な状況の場合は、oneway=-1 とタグ付けすることもできます。
If bicycles are allowed drive the opposite direction tag it with one of the values of cycleway=*!
値
- oneway=yes (非推奨のその他の値: "true", "1")
- oneway=no (非推奨のその他の値: "false", "0")
- oneway=-1 (非推奨のその他の値: "reverse")
その他の値の意味は未定義です。 The oneway-tag may be completely ignored as illegal or may be handled as oneway=yes.
- oneway=reversible is presently used to indicate a road that is one-way at certain times of day, and one-way in the other direction at other times.
- One can also use hour_on:oneway=* and hour_off:oneway=*. A more flexible solution for time-dependent oneways is using oneway:[[:Key:<opening_hours value>|<opening_hours value>]]=* as proposed by Extended conditions for access tags. But this doesn't work in cases where there is no schedule and the roadway direction is set based on current traffic flows on a day-to-day basis.
レンダリング
Osmarender renders little blue and grey arrows at the beginning and end of a oneway street.
Mapnik renders little blue arrows at the beginning and repeats these arrows until the end of a oneway street.
