While a ball-bank indicator was the primary method of setting advisory speeds on horizontal curves, a number of respondents voiced concern about its use. Respondents also underscored the belief "that design speed should always exceed or equal expected operating speed."Equipment includes standard traffic measuring devices (traffic counters, recorders, ball bank indicator); traffic signal controllers, surveying instruments (transit, theodolites, levels, total stationing); roadway design CADD software, and time-lapse still and video photographic equipment.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.She also mounted a ball-bank indicator upside down in the instrument panel, for control coordination in inverted flight, just above the one used for normal flight.

The threshold is set as any curve that has a ball bank indicator reading of 12 degrees or larger qualifies for HFST. 1 Once curves are identified, GDOT Office of Traffic Operations and GDOT District Office identify the limits for the HFST. 1. A 12 degrees of ball-bank should be design for posted speeds of 35 MPH to 45 MPH according to ...
Electronic Ball-Bank Indicator The electronic ball-bank indicator is used to measure lateral acceleration. The electronic ball-bank indicator must have a digital output data stream matching that of the Rieker RDS7-BB-C Digital Ball-Banking Indicator (or Inclinometer). The electronic ball-bank indicator reports the ball-bank angle at a rate of …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 ...Ontario traffic manual ….

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.Enter the email address you signed up with and we'll email you a reset link.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. It was reported in 1995 that 88 percent of states, cities and counties use ball-bank indicators. Since the 1940's ...
