Entrance roads are named in the official language of the region where they are located. They always indicate a certain direction.
Only when Freeways (A-number) also have a European road number, only the E-number is used. In all other cases, the national road number is used.
Exits are named in the official language of the region where they are located (see cityname). If the exit has been numbered, the number must be added to the streetname. Citynames that are mentioned on the road signs, are added to the streetname, seperated by a '/'. Road numbers aren't added to the name of the exit.
Text To Speech (TTS) - ri - di
In case of a (officially) French speaking region, the abbreviation 'di is used, which stands for direction. In the (officially) Dutch and German speaking regions we use 'ri', which stands for the Dutch richting and German richtung.
We've chosen to use an abbreviation so the rest of the instruction stays visible on the screen. These abbreviations are pronounced fully by TTS (Text To Speech), in the navigation instructions with use of streetnames. A win-win situation!
