==General==
In order not to break the KISS principle in the chapter [[Straßen_zuordnen_und_benennen/en|Assigning and naming streets]], we have provided additional information here for those who want to know more precisely why the municipality name is entered in the City field.

The question often arises why the place name, the cadastral municipality or, in the case of larger cities, names of districts are not entered in the city field. This is and has been discussed intensively again and again in the forum. 

It is often argued that this is handled differently in other countries than in Austria.

It can be countered that, even if Waze is a transnational project, the individual countries have to decide for themselves how the country-specific structure should be shown in the map - that's why there is also a separate Austria Wiki.

For the functionality of the client, certain parameters must be taken into account; for example, when searching for addresses and calculating routes, each segment must be clearly addressable. Another parameter is that the number of segments should be as small as possible. Such background information is behind the justification of specifications in the wiki page, which are not specifically listed there due to the desired clarity. Further information related to this can also be found in the chapter [[Wie Waze Routen kalkuliert/en|How Waze calculates routes]].

==Street naming==

If we were to fill the city field with the place name, ALL segments not located within place-name signs would be in a gigantic "No-City" and would then no longer be easily accessible. The community network is nice and close together, without gaps and still more finely structured than districts (in the country with district administration and such, not now the city districts) or even the federal states. It's just important for the way Waze finds the destinations in the background and calculates the route - there can't be this no man's land between the locations.

In Waze, the municipality name is currently the only way in Austria to reduce an area to the lowest denominator. Fields for towns or postcodes have long been eagerly awaited.
Normally, however, a street name in a municipality is unique, even if it takes a lot of getting used to for many, which makes the street naming the necessary uniqueness. This also makes it clear that all segments of a street must have the same designation (spelling !!!) in order to be recognizable as a street for Waze (see routing page keyword [Wie_Waze_Routen_kalkuliert#Fernstreckennetz]) and to minimize the time required for a route calculation.

==Why no districts as City==

In addition, there is the next level of these discussions, which happens again and again, namely the recording of districts (especially in large cities). 

The main argument for this is usually the traffic reports. For this, Waze uses other methods, which are described in more detail in the [Wie_Waze_Routen_kalkuliert#Verkehrsmeldungen].
The additional information value is only for those who are familiar with the area (who do not need a sat-nav at all); those who are not familiar with the area usually do not know the names of the districts anyway. For the purely visual assessment (where am I driving and where is the flag), the entire naming is not relevant.

Für die Routenberechnung hingegen ist das Erfassen von Ortsteilen wiederum kontraproduktiv, da hier nicht einzelne, sondern sehr viele Straßen durch die Ortsteilgrenzen getrennt sind - damit sind die Straßen und das ganze Netz wieder extrem segmentiert, was wieder zu Penalties in der Routenberechnung führt und die Gruppierung von Segmenten erschwert.
==Besonderheiten beim Fernstraßennetz==

Das Fernstraßennetz hat für die Routenberechnung in Waze eine besondere Bedeutung.

Bei den Autobahnen & Schnellstraßen (Freeways) ist das City-Feld auf "No City" zu setzen, da diese innerhalb Österreichs eindeutig sind und durch viele Gemeinden führen. Würde man hier ebenso den Gemeindenamen eintragen, würde bei der Routenkalkulation an jeder Gemeindegrenze segmentiert werden. Das führt zu einem ganzen Haufen völlig nutzloser Fake-Junctions, behindert die Gruppierung der Segmente zu einer durchgehenden Straße und verlängert die Routenberechnung.

Autobahnen muss man als eine Art unabhängigen Korridor sehen, der sich durch ein Land zieht.<br>
