Took me some time to figure out why samples were wrongly matched to crossroads although the bike continued on the main road.
Not sure why direction filtering has been disabled in AnnotateMeasurements on calling
self.roads = Roads(map_source, d_max=point_way_tolerance, d_phi_max=90, cache_dir=cache_dir)
The direction of 90 in fact disables direction filtering resulting in lots of wrong matches to crossroads. Get much better results with the default 40 degrees.
