0 the distance travelled between the time when someone decides to stop a vehicle moving, and the time when the vehicle completely stops:
This allows for a safe stopping distance, even if a train behind violates a signal (the trip arm would trip the train's emergency brakes).
Brake pads with a higher coefficient of friction provide good braking with less brake pedal pressure requirement, but tend to lose efficiency at higher temperatures, increasing stopping distance.
The plume eventually comes to a stop as a result of plume confinement due to ambient atmosphere and the distance at which this happens is called the stopping distance.
However, one hears all sorts of stories about a stopping distance of ten or twelve miles.
The longer the stopping distance, the less margin of safety there is.
It is the stopping distance that counts in an emergency.
One needs 21 ft or 64 m more stopping distance just for that extra 5 mph.
These recommendations include the need for eco-driving, checking the tyre pressure regularly and complying with the stopping distance.
