Ball bank indicator

In 1937 the Missouri State Highway Department began experiments with ball-banking indicators, reporting that a 10-degree ball-bank reading corresponded to an approximate side friction factor of about 0.14 to 0.15, depending on the body roll of the vehicle. .

The RDS7-BB Digital Ball Bank Indicator has been the DOT adopted standard electronic measuring device for determining safe curve speed since the 1990’s. The “-09” version allows the operator to adjust the trip angle setting to the appropriate angle as indicated in your State’s adopted MUTCD (for setting safe curve speed based on road ... Ball Bank Indicator The ball bank indicator (BBI), shown to the right, measures the horizontal forces as a vehicle maneuvers through a curve. These forces are dependent upon the speed of the vehicle and the superelevation (or bank) of the roadway. Measurements are expressed in terms of degree of deflection with which the “ball” travels ...

The reading of the ball-bank indicator should be recorded as minus if the deflection of the ball is to the left on a right hand curve and to the right on a left hand curve. Drive around the curve at a constant speed that can be maintained without acceleration or deceleration and without driving outside the right hand traffic lane.
