maxspeed:type=* is only in used in certain regions of the world, such as the United Kingdom. In other regions for consistency and simplicity of practice the tag source:maxspeed=* should be used instead, which serves the same function in those regions.
This tag can be used to information about the type of speed limit specified in maxspeed=*. More specific, the tag informs about the method how given speed limit had been set into force. This can be, as example
- maxspeed:type=sign - by a speed limit sign for specific road at traffic sign location
- maxspeed:type=FR:urban - by law for roads in residential area
- maxspeed:type=AT:rural - by law for country-side roads
- maxspeed:type=GB:nsl_single - by law for non-motorway single carriageways
- maxspeed:type=NL:motorway - by law for roads with controlled access
- maxspeed:type=PL:rural/maxspeed:type=PL:urban - default speed limits in Poland
In cases where traffic signs had been mapped separate from ways as individual nodes or are missing at all, this tag maxspeed:type=sign informs that current speed limit on a way had been set into force by a traffic sign.
The tag maxspeed:type=* is useful in cases where actual speed limit had been tagged as a hard value like maxspeed=120 which is or was valid by law at time of editing. But law might be changed at some time and maximum allowed speed given by law as well. As long as value of a maxspeed tag had not been changed or should not be changed from a numeric value to preferred context related value like maxspeed=NL:motorway, tag maxspeed:type=* may help to identify such cases by automated procedures.
The tag maxspeed:type=sign may indicate that applicable speed limit may be shown as traffic sign.
The tag maxspeed:type=* with value <country_code>:<context> may indicate that applicable speed limit may be shown as related symbol or icon, especially for rural or urban areas.
How to use
- In cases of an applicable traffic sign using a numeric value for a speed limit: Add tag maxspeed:type=sign
- In cases of an applicable law limits maximum allowed speed limit: Add a tag maxspeed:type=* with value <country_code>:<context>
|Value||When to use||Maxspeed||Taginfo|
||When there are explicit signs stating a speed limit (usually there are also repeater signs every few hundred metres).||Tag maxspeed=* as shown on the sign|
||When there is an implicit 30 mph speed limit, due to the road being single carriageway and there being street lights.||Tag maxspeed=30 mph|
||Single carriageway roads which are national speed limit (the white sign with diagonal black line).||Tag maxspeed=60 mph|
||Dual carriageway roads which are national speed limit (the white sign with diagonal black line).||Tag maxspeed=70 mph|
||Motorways which are national speed limit (the white sign with diagonal black line).||Tag maxspeed=70 mph|
||20 mph zone, there are usually only signs when the zone starts and ends, without repeater signs inside the zone.||Tag maxspeed=20 mph|
