As part of my PhD, I developed a simple way of creating a road network splitting up collected coordinates based on where they cross. I know the standard method is to use a shapefile (or similar) as the network, and match coordinates to it. However, I was not interested in all junctions, simply the junctions where the recorded vehicles went more than one way.
What would be the term for creating a new network?
I have tried looking it up multiple times, but always get directed towards ready-made networks and their analysis.
