Logo. 地物 : 速度制限
One example for 地物 : 速度制限



道路/鉄道/水路の区間に対する最高・最低制限速度は、適切なウェイmaxspeed=* および minspeed=* で定義することができます。

これらのタグには普通は数値が入り、単位が km/h でなければ単位('mph' または 'knots')を接尾辞につけます(km/h の場合は不要)。なお、数値と単位の間にはふつう空白を開けます。ですから、 'maxspeed=30 mph' とするべきであり、 'maxspeed=30mph' は非推奨です。30 km/h の速度は単に 'maxspeed=30' とします。


ウェイの方向別の制限速度については、 maxspeed:forward=* を参照してください。


標識によって、または暗黙的に速度が推奨されているところもあります。これらの速度上限は法的拘束力を持たず、推奨される速度に必ずしも従う必要はありませんが、安全に運転するための速度であり、他のドライバーもどの速度であることが想定できます。この場合は、 maxspeed:advisory=* でタグ付けします。他の条件などが伴う場合は、maxspeed:advisory に続ける (例: maxspeed:advisory:forward=*maxspeed:advisory:conditional=*) 形でタグ付けしてください。


速度制限の標識が実際に設置されている位置を、道路/鉄道/水路の脇に追加情報として追加することができます。これは、traffic_sign=maxspeed (または traffic_sign=minspeed) でタグ付けし、速度制限そのものを表します。たとえば、50 km/hの速度制限を示した標識には maxspeed=50 をつけます。

現在の速度制限を解除する (つまり、デフォルトの速度制限に戻す) 標識は、次のようにマッピングします


Fixed speed cameras can be marked using highway=speed_camera as a node at the location of the camera. For average speed limits use maxspeed:enforcement=* (or alternatively enforcement:maxspeed=*) on the way or the JA:Relation:enforcement. For physical measures on the road see traffic_calming=*.

Legal form and source information, country-specific trends

The meaning of the tag source:maxspeed=* to store information about the legal form of the speed limit (see 'legal form' below for an explanation of this) and the way the data was collected (see 'source' below) is recently disputed by some mappers from the UK (see Situation in the UK below). The international, longest standing and mostly used meaning of source:maxspeed=* is to hold information about the legal form of the speed limit.

'legal form' information

Sometimes a speed limit is given by a nearby sign with a numeric limit, in others the speed limit is given as a legal category where the actual numeric value is prescribed by legislation. By way of example, the speed on motorways in the UK is not shown as a number, but by a diagonal line which for the time being relates to a particular numeric speed of 70 mph for motorways and dual-carriageways and 60 mph for single carriageways.

Some people suggest that source:maxspeed=* should be used for this, others suggest use of maxspeed:type=*. Whichever tag is used, there is agreement that the form of this data should be of the form <country-code>:<category> where the first two letters (in capitals) form a country code and rest defines the type of the limit. By way of example: use 'DE:urban' for the German limit as used in towns, and 'GB:national' for the 'unrestricted' sign found on motorways and other fast roads in the UK.

'source' information

If maxspeed:type=* is being used to hold information about the legal form of the speed limit then source:maxspeed=* can be used to hold information about how the information was gathered. For example source:maxspeed=survey) where the information was collected by a manual ground survey or source:maxspeed=massgis where the date came from an official Massachusetts source in the USA (use suitable text to describe your source). Some people add a date to this, for example source:maxspeed=survey 12 May 2012

Situation in the UK

Some mappers in the UK have subsequently decided to use a different tag maxspeed:type=* for the legal form and use source:maxspeed at object level to hold meta information about how the data was collected. An alternative is also source:maxspeed=*, but generally there is an agreement that source tags should go to the changeset and not to the objects.

Situation in Romania

In a small number of places, notably Romania, the maxspeed tag is used to hold a value of the form '<country-code>:<category>' instead of (source:maxspeed or maxspeed:type).

Country code/category conversion table

Please note, you should tag both, the implied maxspeed explicitly and the source:maxspeed for the reason (sign or country specific area). Commonly used values:

The internal JOSM mappaint style displays maxspeed values tagged on nodes as maxspeed signs. You can also add the map paint style Maxspeed (Preferences -> Map Settings -> Map Paint Styles) and this will show the ways with a maxspeed.
