| Yes. That rings a bell. I used to know how to do quite a few of these tests (and even when to do them), but the student's t-test is just about all I can remember. I suppose that time series like these routes might (be expected to) be skewed to the right; after all, a minimum time might be, say 20 minutes, whereas a maximum time might be a heck of a lot longer due to road work, accidents etc.
It's cool to throw out a p-value, though...
