We could, but you couldn't trust them. (I'm assuming you mean speeds?) Too many factors to be dogmatic about average speeds. Hills, winds, temperature, length of course, type of race (crit, circuit, or road race), number of riders in race, location of race (Belgium faster than U.S.?), general feeling of the pack on any given day, etc...
The best advice is already given here: check out the resources that Six jours & chasm54 are mentioning.
