Safe Braking Distance Alert

SAE Technical Paper Series, 2008
<div class="htmlview paragraph">Since the technology applied to vehicles is constant increasing, new systems are being developed to improve performance, comfort and safety. The main way to improve safety is to keep the driver informed about unsafe traffic.</div> <div class="htmlview paragraph">In this paper we propose the development ...

Computation of Aircraft Braking Distances

Transportation Research Record: Journal of the Transportation Research Board, 2011
Wet runways are known to be a major contributing factor in overrun accidents. Studies have shown that low skid resistance caused by reduced friction on wet pavement leads to a longer braking distance and increases aircraft overrun risk. The common approaches to compute aircraft braking distance and overrun risk are based on either statistical ...

Braking distances as a standard of comparison between brake systems

ATZ worldwide, 2002
For comparing the performance of automotive brake systems, automobile journalists frequently rely on braking distance as this seems to be a quantity which can be measured with particular ease. However, as different methods with different boundary conditions are used for such tests, readers find it difficult to weigh the published tests results.

Aerodynamic Brake Study of Reducing Braking Distance and Decreasing Using The Energy of Braking of High-Speed Trains

2020 International Conference on Power, Energy and Innovations (ICPEI), 2020
This article presents a novel research on aerodynamic brake by reducing brake distance and braking energy of the high-speed trains (HST), which is inspirational from the aerodynamic brake on a commercial aircraft’s wings. In emergency case, both brake distance and braking time of HST will be longer than normal situation, therefore, safety for ...

Truck braking distance and speed estimates

Canadian Journal of Civil Engineering, 1986
The most frequently cited cause of truck accidents is “speed too fast for prevailing conditions.” To cite this cause, a speed estimate is necessary. This paper shows the factors that should be considered. The factors most useful in estimating a truck's braking capability include vehicle configuration, loading, location of the centre of mass, and axles

Braking Distance Monitoring System for Escalator

2018
In the design, manufacture, use and test of escalator, the measurement of braking performance is very important. The braking distance of escalator is the most important parameter to judge its braking performance. In this thesis an effective mode to use wireless remote control technology as information transport platform for wireless monitoring system ...

Deceleration Rates for Safe Braking Distance Calculations

2017 Joint Rail Conference, 2017
IEEE 1698, Guidelines for Safe Braking Distance Calculations - 2009 brakes down the determination of stopping distance for train control system into separate independent events. One of the most misunderstood portions of the model is Parts I and H (train deceleration).

Adhesion Considerations in Safe Braking Distance Calculations

2015 Joint Rail Conference, 2015
The main objective in optimizing train control is to eliminate the waste associated with the use of “worst case” assumptions to calculate Safe Braking Distances (SBD). Worst case takes the most conservative approach to the determination of train stopping distance in order to provide adequate stopping distance under virtually all conditions.

Train Braking Distance Estimation Under Different Operating Conditions

ASME 2011 Rail Transportation Division Fall Technical Conference, 2011
One of the critical factors in Positive Train Control (PTC) is accurately estimating the train braking distance under different conditions. Accurate estimation of the braking distance will allow the trains to be spaced closer together, with reasonable confidence that they will stop without causing a collision. This study will develop a dynamic model of
