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? Even more, I would be interested in a whole benchmark/test suite for this purpose.

  • If you are seeking open data then the place to ask will be the Open Data Stack Exchange. – PolyGeo Mar 4 '18 at 0:46
  • Would be interested to know if such a thing exists for evaluating our own system as well. Maybe some of the traces of openstreetmap? – Fabrice Marchal Mar 4 '18 at 9:53

This paper by Newsom and Krumm on map-matching includes a test dataset that you can use to evaluate other algorithms. It's called "Hidden Markov Map Matching Through Noise and Sparseness."

  • I know this article, but I don't think that one trace is enough for benchmarking. – Fido Aug 7 '19 at 17:50

Finally, I've found trace dataset suitable for the benchmarking, containing 100 traces from different parts of the world. It is described in the article called Dataset for testing and training of map-matching algorithms by Kubicka et al. (available on IEEE).

The dataset itself is stored on zenodo.org as an open-access dataset.
