Is 'travers' also related to 'tracking'?


Only if you can construe that "traversing" is related to "tracking"... Plus, the phrase is à travers, which must be considered as a whole (as with "by and large," for example).

Plus, just to keep things nicely muddied-up, the very word "track" (as used in "soundtrack" or "music track") has a pretty specialized meaning that doesn't link too directly with "track" in its more generic sense.
