The runway is banked, and the angle of the bank is proportional to the radius. Anything moving along the runway, at any speed, should naturally stay on the runway. Slower objects will roll towards the inner, flatter area, and faster objects will zip around the high rim.
The word you want is not banked, it is curved. Unless you say it is progressively banked, but that's solely an unnecessarily loquacious means of stating the same precise thing. But that's just another undesirable added complexity. Now if you don't touch down at the correct lateral position for your airspeed, you're going to have to deal with the runway trying to either dump you off the bottom, or squirt you off the top.
