Hi Martin, you will not get a correct solution for this problem. Your road network and the gps points differs always.
A possible "solution" is building a buffer around the streets und look für intersection with gps points and filter by direction road/points. Grouping gps points can give you the start and end point for the road. If a road is only one times driven.
