Werkzeuge für dieses Attribut

Diese Eigenschaft wird für Straßen verwendet, die durch eine Verkehrsbeeinflussungsanlage verschiedene Höchstgeschwindigkeiten zulässt.

Werte

key/value Beschreibung
maxspeed:variable=yes Zeigt an, dass die mit dem Tag maxspeed=* angegebene Geschwindigkeit eine maximale Geschwindigkeitsbegrenzung darstellt und mithilfe einer dynamischen Geschwindigkeitsanzeige weiter verringert werden kann.

Dies ersetzt maxspeed=signals.

maxspeed:variable=<Grund> Gleiche Bedeutung wie oben, gibt jedoch zusätzlich Gründe für die Geschwindigkeitsanpassung an. Mögliche Werte finden Sie im nächsten Abschnitt.
maxspeed:variable=no Standardwert. Zeigt an, dass die in maxspeed=* Tagging angegebene Geschwindigkeit ein fester Grenzwert ist.
Feste Grenzwerte können abhängig von den Bedingungen variieren, z.B. Uhrzeit.
maxspeed:variable:forward=*
maxspeed:variable:backward=*		 Gleiche Bedeutung wie oben – diese Tags wirken sich jedoch nur auf die Vorwärts- bzw. Rückwärtsrichtung aus. Wenn vorhanden, überschreibt dies maxspeed:variable=*.

Werte für <Grund>

Der Wert kann zusätzliche Informationen darüber liefern, warum das Tempolimit im Abschnitt "Variables Tempolimit" geändert wird. Sie sollten von Personen beobachtet werden können, die häufig den Abschnitt mit der variablen Geschwindigkeitsbegrenzung verwenden. Wenn der Grund nicht bekannt ist, verwenden Sie bitte yes.

Die Werte geben einen Hinweis auf die Häufigkeit einer Geschwindigkeitsbegrenzung.

maxspeed:variable value Description Example
peak_traffic The speed limit is frequently lowered (from the given maxspeed) on high traffic loads during peak hours on many days of the year. Traffic management systems reduce the speed limit to optimize traffic thoughput by harmonizing the speed of the vehicles, to reduce the inflow traffic into a congested section and also for safety reasons to lower the speed before queues.

The value peak_traffic includes obstruction, adding obstruction to the value (separated by ';') is unnecessary.

Note: This value is not intended for sections with occasional traffic peaks (e.g. start of holidays, an annual concert), even if the variable speed limits is reduced in such situations too. Use obstruction instead.
Speed limit 40 because of dense traffic (rush hour)
weather This value indicates that the speed limit changes with the weather conditions. Most modern traffic management systems have sensors to detect wet road conditions, snow/ice or fog. The information can be used to reduce speed for increased safety.

Note: Only use maxspeed:variable=weather if the speed limit is affected by the weather, not if just warning signs are displayed.

Illustration only, variable speed limit not visible on this picture.

environment The speed limit can be reduced to protect the environment and/or nearby residents (e.g. to reduce emissions, smog or noise).

Note: This value (and maxspeed:variable in general) is not intended for permanent but e.g. time dependent speed reductions like even if they have been installed for environmental reasons (smog, noise). Use maxspeed:conditional=* instead.
Variable speed limit of 100, activated to reduce emissions (indicated by IG-L)
school_zone A lower speed limit is indicated due to children in nearby schools.

Note: This is not a generic tag for school zones. It only applies to school zones where the lower speed limit is changed or indicated externally (for example by switching on flashing lights or changing a digital display) and not just with static signs. For static signs with written conditions like "when children are present", "on school days" or fixed times or days (Mo-Fr, 8-16), please use maxspeed:conditional=* and do not tag it with maxspeed:variable.

 or Speed limit sign operated from inside of school
obstruction The speed limit is lowered exceptionally in cases like accidents or breakdowns, on occasional traffic peaks (few days of year only, for example start or end of school holidays), road works or other traffic obstructions ahead.

Note: Variable speed limits in tunnels and at tunnel portals outside urban areas are candidates for maxspeed:variable=obstruction.

Here the tunnel has been completely closed due a car break down ("Panne"), the reduced variable speed limit would be 30.

Examples

  • maxspeed:variable=yes, maxspeed=80 – indicates that the maximum allowed speed is 80 kmph, however, this speed limit can be reduced further to accomodate traffic conditions
  • maxspeed:variable=yes, maxspeed=none – indicates that there is no maximum allowed speed (no legal limit!), however, the speed limit can be reduced if necessary. Normally only useful on German Autobahn.
