If the aim is to actually smooth lines, this was posted recently to the list: 


it uses R to accomplish the task.  The links at the bottom are still active as well for the sample output that was created.

I'm sorry, but this question does not have enough detail to understand
what you want to do.

o convert point to lines?
o smooth how? moving average?
o why do you think you need to smooth your tracks?
o are you asking about map matching your tracks to a road network?

I just guessing here, so give a little more details.
