hmm model misses out last few gps points #14

Hi Guys

I am trying to use the hmm model for map-matching. After running the hmm algo for various datasets, I found out that the algorithm does not match the last few data points (gps) to desired road nodes. It maps these data points to the road nodes occurring much before it.
Please find the screenshots. The highlights portion in blue color shows the points which are not matched properly.

Thanks

I am also facing the same problem. Did you get any solution?

Try increasing the variable 'dist', which is by default set to 1000.
if you still face the same issue, let me know.
