2 years ago In your example, the GPS id field is used to determine the trajectory from the GPS points, you have a single trajectory so you need to have the same ID, but different timestamps.

Hi, thank you for sharing this wonderful software.
With open data, "Dataset for testing and training map-matching methods" https://zenodo.org/record/57731#.YV-lbBrP3Zv I implemented the fmm and used the data from "00000001". The data converted to a shapefile is copied here. https://www.dropbox.com/s/swwicff3lc68239/test_data.zip?dl=0
The problem I am facing is shown in the attached. results.pdf The "cpath" from edge 139208 should go to 8970 via 133950, but it skips 133950. (The content seems to be identical to “opath”). I have checked the geometry, source and target of shape file, and everything seems to be fine for this place. The settings I used are shown below for reference. Do you have any idea why this is happening?
