The term "Ball Bank Indicator" refers to an inclinometer that is used for the specific purpose of determining safe (uniform advisory) curve speeds for horizontal curves. It measures the overturning force (side friction), measured in degrees, on a vehicle negotiating a horizontal curve - whether it is an isolated curve, multiple "S" curve, or a ...The ball bank indicator has been used since the 1930s to measure the speed at which occupants become uncomfortable. Reported in degrees, the reading of the ball bank indicator is the sum of a vehicle’s lateral acceleration and the body-roll minus the roadway superelevation.ball bank indicator method. 5. Advisory speed plates (mph) should be used in conjunction with curve and turn signs when the operating speed is below the posted or prevailing speed on the roadway. When plates are used with curve and turn signs, the miles-per-hour value shown on each plate should be determined by the use of the ball-bank indicator.
