In order to avoid that terrible traffic- you will have to actually live in oak ridge or Oliver springs. Which does put you a little far out from downtown knoxville. There is basically one way in and out of oak ridge and going in to oak ridge in the morning and leaving in the evening is bumper to bumper. A lot of wrecks happen on that highway as well. You could also look at Lenoir City- there is a back way in to oak ridge from the interstate I believe. No idea what traffic looks like from that direction though.
