The 'easiest' way I see is to compare those results with the same calculation based on data from a week or a month old. Wherever the difference in time / distance is more than a certain threshold, say 5 or 10%, the route needs to be looked at. More elaborate method is to look at the spatial correlation between old and new route, and make a map showing the routes where new diverges from old more than a certain threshold. That said, I don't really know how ot do either offhand, but hope it helps anyway.
