There is no standard. I even observed someone merging bus stops for 
different directions into one "because it looks better on the map".

This is the first that I ever hear from that scheme. But after reading 
it: how do split roundabouts and different relations for forward and 
backward not fit in this model?

I had made a start documenting Dutch busroutes [1], but I also see that 
I'm more or less the only one using it.
I don't know how it is done outside Limburg, but in Limburg the 
relations are IIRC not grouped. I'm also not entirely sure how we should 
group them. In Germany there is a strong grouping in the 
Verkehrsverbünde. We don't have that. We do have concessionareas, but 
these can be large (Limburg is one concession, run by Veolia) and can 
overlap (in Amsterdam, you'll find busses from different concessions).
Currently the logical division in Limburg is North/Middle, South, 
Parkstad, citylines Venlo, citylines Roermond, citylines Maastricht. 
This is a historical division based on buscompanies starting 60 years 
ago.
