The ball-bank indicator has been accepted by a majority of the states as a procedure for the determination of safe driving speeds on curves. The criteria that were developed in the late 1930s and early 1940s are still basically used today, practically unchanged from the initial recommendations.

A BBI measures the combination of lateralBall 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 first gyroscopic aircraft instrument was the turn indicator in the needle and ball, or turn-and-bank indicator, which has more recently been called a turn-and-slip indicator.

In a Ball Bank Indicator, a ball held in fluid moves in response to travelling around a curve. The goal of a ball bank study is to determine the speed of travel where the ball stays below the maximum reading. The posted speed is usually rounded down to the nearest 5 mph. It is important to follow correct procedures when using the ball bank ...Basic ball bank indicator (BBI) • Advanced BBI • Chord length • Compass • Field survey • Global Positioning System (GPS) unit • Lateral acceleration • Plan sheet • Speed advisory plate • Vehicle yaw rate .

Respondents also underscored the belief "that design speed should always exceed or equal expected operating speed."Ball bank indicator readings were correlated with lateral acceleration rates. Additionally, the influence of vehicular body-roll on ball bank indicator readings was investigated.determining appropriate and uniform speeds for such signs has long been the ball-bank indicator; however, debates over suitable ball-bank thresholds continue and inconsistent standards between jurisdictions persist. Moreover, research regarding the effectiveness of advisory speed/curve signs in general has been long neglected.

NYSDOT came through for me. The paper discusses the effect of body roll rate on the ball bank indicator. The authors state that a sports car will roll 3 degrees per 1 g of lateral acceleration, and a passenger car is around 7 deg/g. This, they calculate, results in a .48 degree difference in ball bank indication at 100 km/h. lawrence ks personal trainer Topic No. 750-000-005 March 1999 Traffic Engineering Manual Revised: November 2017 Signs Use of Slippery When Wet Signs 2-1-1 Section 2.1 USE OF SLIPPERY WHEN WET SIGNS 2.1.1 CONDElectronic Ball-Bank Indicator The electronic ball-bank indicator is used to measure lateral acceleration.
