On the map of Belgium the highways have an Axx number/name, but we are accustomed to the European Exx naming.E.g.
A1=E19
A2=E314
A3=E40 but A10 is also a part of E40
A4=E411 and E25
A13=E313
and so on...
On singposts only the E-naming is used. A-numbers are only used by national administrations, not by (road) users.
Would it be possible to use the most common naming?
