Ed Thanks a lot - that is all very clear and helpful and makes perfect sense. I will follow your example.
I already tend to average ways where necessary in similar manner to your description and, as I almost always am doing walking surveys, any bus stops that I have manually added have indeed been done stationary at the stop.
