Status: de facto

The maxspeed=* tag is used on ways to define the maximum legal speed limit for general traffic on a particular road, railway, or waterway. By default, values will be interpreted as kilometers per hour. The speedlimit can be specified in different units if necessary. Those will be added behind the value, separated by a space (see Examples). The tag is also used on nodes to specify maxspeed traffic signs.

Values

The maximum speed limit for a highway=*, railway=rail, waterway=river etc. can be specified as follows:
While the tagging examples are given for linear features, single positions with restrictions can usually be mapped by tagging a node with the same tags.

Type Example Meaning
Numeric speed limit maxspeed=60
maxspeed=50 mph
maxspeed=10 knots
The maximum fixed numeric speed limit, followed by the appropriate unit, if not measured in km/h. When the value is in km/h then no unit should be included. For example, maxspeed=60 for 60 km/h and maxspeed=50 mph for 50 mph (note the space between the value and the unit).
Variable speed limit maxspeed:variable=*
Main article: Key:maxspeed:variable

Indicates that a variable maximum speed can be displayed on electronic variable message signs, for reasons indicated in the tag's value. Can be used together with maxspeed=* to indicate the speed limit in the normal situation.

Please do not use this tag for railway lines, and tag instead the maximum allowed speed there.

No speed limit maxspeed=none Indicates that there is no fixed maximum numeric speed limit for this section of road (on some German autobahns and a very few other places). Not to be used for situations where there is a limit, but it is not known. Where the limit is not known, do not include a maxspeed tag.
Walking speed limit maxspeed=walk In Austria and Germany, the speed limit for living street (German: Wohnstraße bzw. Verkehrsberuhigter Bereich) is defined only as being a walking speed, but there is no defined numeric value for this. The maxspeed walk proposal suggests that walk should be used, but it is not commonly used.

If the law defines a numeric equivalent, that can be used instead. For example, in the Netherlands, walking speed is legally defined as 15 km/h, so one simply uses maxspeed=15 instead of maxspeed=walk.

Implicit speed limit maxspeed=<countrycode>:<zone type> In some countries, notably Romania and Russia, it's common to use maxspeed with implicit values. The format includes a country code followed by a ':' and a zone identifier (For example 'RO:urban'). For example it is used in Russia for areas where the speed limit is indicated on the street by use of a symbol or icon rather than a number.

This non-numeric notation is used to avoid the correction of an entire country map due to legislation changes regarding maximum speed.

Note: Some local communities, prefers to tag the same information in the tag maxspeed:type=* and the tag source:maxspeed=* is also common in some communities. A project wide consens how this information is tagged was not found, yet.

Implicit maxspeed values

Main article: Default speed limits

The maxspeed=* tag may use with context-specific values, such as where a road is unsigned and a "default" maxspeed value in-force by legislation/law applies.

Note: In some communities this information is commonly tagged in source:maxspeed=* or maxspeed:type=*.

Maxspeed zones

Where the speed limit is indicated by special speed limits signposted at the zone boundaries, they can be tagged as follows:

maxspeed=30
maxspeed:type=DE:zone30

or less commonly with maxspeed=DE:zone:30.

Note: The dedicated key zone:maxspeed=* overlaps with both methods and can be used for this purpose in combination with an explicit maxspeed value, e.g zone:maxspeed=DE:30 and maxspeed=30.

Extended tagging

Vehicles

Where different speed limits are posted for different classes of vehicles, these should be specified using maxspeed:<vehicle>=*. The possible values for <vehicle> correspond to the values for transport modes of the key access=* (see also Examples).

Note: Where a lower blanket speed limit is applied for certain classes of vehicle across all roads within the jurisdiction, then this should not be tagged at the individual road level.

For example:

Driving direction

Main article: Forward & backward, left & right

Where different speed limits are specified for each driving direction, those can be specified using maxspeed:forward=* resp. maxspeed:backward=*, whereas forward applies to the speed limit for the same direction as the OSM way and backward to the speed limit for the opposite direction.

Lanes

Where different speed limits are specified for each lane of a road, those can be specified using maxspeed:lanes=*. Each lane’s maximum speed has to be separated with the “|” character. The first maximum speed is the maximum speed of the leftmost lane (viewed from the direction of the OSM way), the second maximum speed is the speed of the lane right from the leftmost lane and so on until the rightmost lane. Further, if they should be specified for each driving direction separately the key maxspeed:lanes:forward=* resp. maxspeed:lanes:backward=* can be used, whereas lanes:forward applies to the speed limit of the lanes for the same direction as the OSM way and lanes:backward to the speed limit of the lanes of the opposite direction. See therefore also the Examples as well as the article about mapping individual lanes.

Time or other conditions

Main article: Conditional restrictions

Example: The maximum speed is 30 km/h between 7am and 2pm on workdays (in Germany: Monday-Saturday, but not on public holidays) but otherwise is 50 km/h as implicit speed limit in the city:
maxspeed=50
source:maxspeed=DE:urban
maxspeed:conditional=30 @ (Mo-Sa 07:00-14:00; PH off)

Other considerations

The maxspeed=* tag should ideally be added to only the segment of roadway for which the speed limit applies. Depending on the jurisdiction, a speed limit may take effect at a speed limit sign [1][2], at a solid line painted across the roadway near the sign [3], at a fixed distance away from the sign, or at the nearest intersection.

Services

  • JOSM
    • The default internal mappaint style displays the value of maxspeed on a node if tagged together with traffic_sign=* as traffic sign.
    • The mappaint style maxspeed displays the value of maxspeed on ways as coloured underlay.
  • StreetComplete has a quest (disabled by default) that asks about max speed info
  • MapComplete Maxspeed editor (does not support the use of *:urban tags)
  • Other services:
    • Worldwide maxspeed overlay. Only compatible with maxspeed default unit. No support for mph.
    • Overpass turbo queries. Does not read values with km/h or mph, only the implied default unit.
      • Maxspeed coloured similar colour style to previous ITO map (Yellow for maxspeed of 'none'. dark blue for 130/120/110. light blue for 100, purple for 90/80, red for 70/60 orange for 50 and green for 5/10/15/20/30/40)
      • Maxspeed major roads coloured similar colour style to previous ITO map (Yellow is used for ways with maxspeed set to 'none', dark blue for 130/120/110, light blue for 100, purple for 90/80, red for 70/60, orange for 50 and green for 30

Parser

Regular expression for numeric values only:

^([0-9][\.0-9]+?)(?:[ ]?(?:km/h|kmh|kph|mph|knots))?$

Regular expression which catches numeric values and implicit values, e.g. like none or signals:

^([^ ]+?)(?:[ ]?(?:km/h|kmh|kph|mph|knots))?$

One mile per hour corresponds to 1.609 km/h and one  knot to 1.852 kilometres per hour.

Routers

Router developers should be aware that the highway=* tag is not necessarily a good proxy for speed limits in some jurisdictions. For example, in the U.S. state of Ohio, many factors affect a roadway's speed limit, to the extent that rural, unpaved highway=unclassified ways have a higher speed limit by default (55 mph) than some urban highway=motorway ways (50 mph).

Notes and references

  1. Applies to both urban and rural areas, where no signs exist. That said, most roads and highways in Saskatchewan have posted limits, commonly 50 in urban areas, 80 in most rural roads, 100 in undivided provincial highways, and 110 in divided provincial highways.
  2. https://lebenswerte-staedte.de
  3. 130 km/h is the recommended maximum speed on motorways, as indicated by a square blue sign (round blue sign = minimum speed). Many sections of the German motorway network are now covered by speed limits, usually ranging from 80 to 130 km/h (140 km/h as speed limit is being tested in Lower Saxony -some politicians are against it, because 140 km/h is over the recommended maximum speed, depending on local conditions (i.e., frequent traffic, terrain, etc.). It is usual for drivers involved in crashes who were exceeding the 'recommended' speed limit to be held to be at least partly at fault, regardless of the circumstances of the crash, and insurance companies have the right to withhold payment. Already more than 50% Autobahns now have a (partially variable) speed limit. Vehicles also must be able to go faster than 60 km/h. Roughly 30% of German Autobahn have permanent limits. An additional 17% have at least partial limits depending on time, weather or traffic. Study on the speed limit on German Autobahn. Archived 25 May 2013 at the Wayback Machine.

  6. This value seems unnecessary, since the speed limit of 50 km/h in urban areas is always signed at the entrance of the settlement by road sign 2.30.1.
