Thanks Philip, The two selected nodes are the starting and ending points.
I know that interpolation can be out by tens of meters, due to varying plot sizes. Even worse is that I intend to use even interpolation for suburbs where the increment is 4 (for example, Nominatim thinks that 328 Edna,Pretoria exists, while it doesn't). But collecting these details will make the projectsmuch too large. I'll help you with writing the code that generates the parallel ways. It will take a list of lat/long pairs (the road) and produces another list of lat/long pairs (the new way). Assuming it's a Josm plugin, I'll do it in Java.
