Moreover, research regarding the effectiveness of advisory speed/curve signs in general has been long neglected.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. The proposed speed limits are based on speed studies, topography, and ball-bank indicator tests performed on the horizontal curves. RESO - Gunnison Rd speed limit 9.6.23.pdf.

Unlike regulatory signs, which are determined by the law, advisory speeds are based on physics. A scientific instrument called a ball bank indicator allows ...An example of a ball-bank reading is illustrated below in Figure 2. Figure 2 - A display with ball-bank indicator readings. Table 1 shows the maximum ball-bank reading to be used when determining the maximum safe operating speed. Table 1 Maximum Ball-Bank Reading Maximum Safe Operating Speed (Paved surfaces) 10° Speeds 55 to 100 km/h may be Oct 15, 2014 · The ball-bank indicator must be mounted in the vehicle so that it displays a 0-degree reading when the vehicle is stopped on a level surface. The positioning of the ball-bank indicator is checked before starting any test. This can be done by stopping the car so that its wheels straddle the centerline of a two-lane highway on a tangent alignment.

Jan 9, 2008 · 9 Jan 08 16:10. 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. One device widely used for establishing advisory speeds on curves is the ball bank indicator.
