[GraphHopper] Does Graphhopper merge ways with equal flags and name?

[John Zhao]

Hi,

AFAIK, there is no this kind of merging logic here.
Wait the answer from Peter.
Probably you need to implement it by your own.
And it's not easy.
Maybe can be done before import?
What you want, is actually convert a tower node to a pillar node.
