I map matched a sequence of GPS-points to a road network using the Offline-Map Matching plugin for QGIS. This map matched trajectory passes certain roads segments multiple times (for example, the selected red matched trajectory segment in the picture below has two unique fid numbers, 60 and 359, see left).
In the picture below, only trajectory with fid 60 is selected. As you can see, these trajectory segments are generated between two consecutive GPS points.
In order to visualise where most vehicle activity occurred in the network (with the line thickness/size being proportional to the number of overlapping map matched trajectories), I need to analyse the number of overlapping map-matched trajectories per road link in the road network.
I have tried several things but unfortunately without success. Any ideas on how to do this in QGIS?
