yes,I only need to use the tracks to add roads to OSM once for each road at the first time,but the problem is that how can I know whick roads are missing,especial even the same road can have different GPS points in different gpx files.

it is a small city for china, the current data in OSM about the city is not enough, many roads are missing,so I need to use the 100,000 gpx files to add the missing roads,so i can get the bicycle distance between different points of the city.

of course, they are many repeated roads in  the 100,000 gpx files, what I need is the actual way info, how can I find them out?

You probably don't want to use the tracks directly to add roads to OSM (you would only want to do this once in any case). Definitely they could be useful for detecting which roads are missing, and, if the available aerial imagery  isn't good enough for actually adding any missing roads. 
Can you indicate where the city is?

my ios app has 10,000 users in one city, and they wii collect the trajectory in gpx format, i want to add way to  openstreetmap use their gpx trajectory.

there will be almost 100,000 gpx files one day, so it is not possible to edit map manual by software such as JOSN.

I want to know if I can product ways accord to the 100,0000 gpx files automatic,I need a C++ library which can do this,can anyone help me please?
