Map Matching Issue

[AshmoreLevi]

I'm having problems performing road network matching of track points:
1, Have you reproduced the map matching code for the tktp tool provided in MTrajRec? I get all null values None after running the road network matching.
2、After running the hmm.cpp you provided, I got an error segmentation fault (core dumped). What is the possible reason for this?
Looking forward thank you for your reply!

Sorry for the issue, the provided hmm.cpp is not an official code of the paper. You can use the tktp tool provided in MTrajRec for map matching and adjusting the data format of the road network and trajectory to our format. Also, if you prefer the code from MTrajRec, you can also feel free to use their codes and copy the network and dataset definitions to their repository.
