Traditionally, highway engineers applied the Ball-Bank indicator to capture drivers' feelings of discomfort on highway curves, but this research demonstrated that the brainwave test would be a better alternative. Recommended. Recommended Superelevation, Side Friction, and Roadway Consistency ...The Rieker digital ball bank is a digital inclinometer that can be used to assist in completing an engineering study to determine advisory speeds in curves. The unit provides two measurements (right and left) of the degree of bank collected when passing through a curve. The larger of these values collected for each data collection pass ... process referred to as the Direct Method and other traditional methods (such as the ball-bank indicator), which are generally assumed to produce accurate results. Comparing the results of these methods lets researchers evaluate their accuracy and usefulness for setting advisory speeds.For decades, the ball bank indicator method is one of the most commonly used methods by engineers worldwide for determining driver discomfort that correlates to setting the advisory speed. Setup your phone on your dashboard like you would typically setup a ball bank device. Press Start and drive. No need for a second person to write down the ...

Title: Review of the procedure for curve advisory speed determination: Author: Preisler=F (Connell Wagner (Queensland)) Broadhurst=KJ (Queensland. Department of Transport)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 ramp to/from a freeway.The Ball-Bank Indicator Method is based on a set of field driving tests to record ball-bank indicator reading using a ball-bank indicator and a speedometer. There are varied criteria for establishing the curve advisory speed based on ball-bank indicator readings.The meaning of BALL-BANK INDICATOR is a bank indicator consisting of a slightly curved tube in which a ball remains centered while the airplane is flying straight and level or while the airplane is making a properly banked turn.Traffic Operational Impacts of Higher-Conspicuity Sign Materials

Dec 6, 2021 · This ball is located in a tube filled with fluid and can move freely to the right and left. For example, when the ball is displaced to the left, this informs the pilot that left rudder input is required. The bank angle information is provided either by a miniature aircraft or a vertical line that rotates in the direction of the bank. For decades, the ball bank indicator method is one of the most commonly used methods by engineers worldwide for determining driver discomfort that correlates to setting the advisory speed.
