M. Kubicka, A. Cela, P. Moulin, H. Mounier, and S. I. Niculescu, "Dataset for testing and training of map-matching algorithms", in 2015 IEEE Intelligent Vehicles Symposium (IV), Jun. 2015, doi: 10.1109/ivs.2015.7225829
Worldwide map matching dataset to download from:
https://doi.org/10.5281/zenodo.57731
Unzip the map-matching-dataset.zip zip file and place in this directory
the map-matching-dataset folder that contains everything.
The data set is hand-corrected and thus contains some matching errors.
The following commands need to be run from the base map_matching_2,
the path to the map_matching_2 executable can be adjusted as needed, e.g.,
for GCC: run/gcc/release/bin/map_matching_2,
for Clang: run/clang/release/bin/map_matching_2,
for MSVC: run\msvc\release\bin\map_matching_2.exe.
# prepare networks
./map_matching_2 --conf data/kubicka-et-al/conf/prepare.conf
# prepare ground truth networks (not simplified!)
./map_matching_2 --conf data/kubicka-et-al/conf/prepare_ground_truth.conf
# convert ground truth routes
./map_matching_2 --conf data/kubicka-et-al/conf/ground_truth.conf
# match tracks
./map_matching_2 --conf data/kubicka-et-al/conf/match.conf
# match tracks with export-edges mode (uses the slower ground truth network!)
./map_matching_2 --conf data/kubicka-et-al/conf/match_edges.conf
# compare matches with ground truth
./map_matching_2 --conf data/kubicka-et-al/conf/compare.conf
# compare export-edges matches with ground truth
./map_matching_2 --conf data/kubicka-et-al/conf/compare_edges.conf
The results will be in the results folder that is automatically created.
Results on our test system (accuracy is the weighted mean correct fraction in percent):
| Mode | Time (s) | Max RAM (MiB) | Accuracy (%) |
|---|---|---|---|
| Prepare | 31.24 | 2,717 | N/A |
| Prepare * | 16.24 | 1,761 | N/A |
| Prepare (Ground Truth) | 25.98 | 2,640 | N/A |
| Prepare (Ground Truth) * | 20.64 | 2,553 | N/A |
| Convert Ground Truth | 8.69 | 1,303 | N/A |
| Match | 7.77 | 1,220 | N/A |
| Match (Export-Edges) | 28.82 | 2,934 | N/A |
| Compare | 0.94 | 41 | 98.73 |
| Compare (Export-Edges) | 0.90 | 55 | 98.93 |
Max RAM contains shared memory (cached memory backed by disk, not actually used).
The prepare runs marked with * were run with --memory-mapped-preparation off.
In this case, only the final data is written into memory mapped files and during the preparation,
non-cached RAM (actually used by the process) is used.
