43、 Guide for the Calculation of Braking Distances for Rail Transit Vehicles 2. Definitions, acronyms, and abbreviations 2.1 Definitions For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionary: Glossary of Terms the tangent of the angle formed by the

44、algebraic value of the rise divided by the horizontal component of the run, typically expressed as a percent. gradient: The horizontal run over which one unit of rise occurs. jerk rate limit: The limit to the rate of change of acceleration designed into the propulsion, automatic train operation (ATO

45、), and/or braking apparatus. maximum attainable speed: An entry speed, commonly used with trip-stops with wayside signals, which is the highest speed that a train can achieve at the entry point of the braking model while operating in accordance with the rules of the authority having jurisdiction. ma

46、ximum authorized speed: The highest speed at which a train is allowed to operate in the absence of any condition requiring a lesser speed. operator reaction time: The time from passage of an entry point until an operator has performed a definitive action in recognition of the existence of a more res

47、trictive speed limit. 1The IEEE Standards Dictionary: Glossary of Terms specific transit applications may not require use of all model components. The “worst-case” combination of parameters applicable to the vehicles (or combination(s) of vehicles) and physical location(s) being analyzed, as used in

48、 calculations, is defined by the authority having jurisdiction. Where a component is not to be included, the development of a comprehensive failure analysis supporting this decision is strongly recommended. Similarly, failure modes or other specific conditions considered and all components values us

49、ed should be validated by supporting analysis and test results wherever possible. A simplified illustration of the braking model is shown in Figure 1. 3 Copyright 2009 IEEE. All rights reserved.
