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.
