SMR ?!? man you are in Poland !! they don't even have radar (yet) for the approach in Wroclaw !!
It needs proper signs at WRO for taxiways (not so many taxiways in WRO!), hold short position illuminated on both side of runway(nothing on north side), a bloody centerline light on the runway, nothing more, well that means money, and in Poland they don't have much... (and some pilots to scratch their heads when they take off with blue lights on the side
)
when you take off in low vis it is also wise to have the LLZ centered (WRO has ILS on 29)
There is a fantastic system with synthetic voice that says ("approaching runway XX", "On runway XX", I can't remeber the name of that system, I already heard it on a Luthansa 737, impressive ! (I think it works with localizers , not with Gps), both an excellent safety equipment for runway incursion and runways/taxiways confusions.
