I have my own map matching algorithm and I want to compare it's accuracy to some other algorithms. Is there a free trace dataset that has a confirmed match for each trace (ground truth), so I can perform the comparison?
Your question is pretty old now, but I'm looking for the same stuff and found this article so far: https://ieeexplore.ieee.org/document/7225829
The corresponding dataset (described in this article) can be found here: https://zenodo.org/record/57731#.XDS-Plz0laQ
Maybe this helps you. If you found something yourself in the meantime I would appreciate it if you could share/link it here.
