Superelevation Transitions Consists of Tangent Runout and Superelevation Runoff Sections • Runout: length of roadway needed to accomplish a change in outside lane cross slope from normal rate to zero • Runoff: length of roadway needed to accomplish a change in outside lane cross slope from zero to full
