What is the stopping distance?
The braking distance is the distance to which the vehicle will move from the beginning of the brake system to its full stop in the direction of its initial movement. It is important not to confuse this concept with the notion of a stopover. The stopping distance is the distance that the vehicle will pass from the moment when the driver recognizes the need for braking and until the vehicle stops driving. That is, to the first definition we add the time spent by the driver to react, and the time of the brake system activation, and we get the second. Both of these concepts are inextricably tied to any land vehicle that has a braking mechanism.
Parameters of the road surface (primer, asphalt, concrete);
The quality and degree of deterioration of the tread (summer tires in winter will prolong the way to the nearest obstacle, and the winter in summer will bring out in the pool for aquaplaning and there);
Weather conditions (dry, rain, snow);
The condition of the brakes themselves (whether the pads are good, whether the hydraulics flow, etc.);
The presence or absence of an anti - lock system (ABS prevents the wheel from locking and allows you to use frictional force more effectively and retain control over the control);
The degree of congestion of the car (the heavier the transport, the greater inertia it has);
Initial speed (the most important factor, the length of the braking distance depends directly on the square of the speed of the car).
As is clear from the above, the stopping distance is a variable quantity, the empirical and theoretical approach can determine it very inaccurately. Usually, along the length of the path, the initial speed of the vehicle is calculated when an accident is committed. For the driver, on the contrary, it is important to know how much will slow down his car at this speed.
The brake way of a train is generally a separate topic.
It is important to remember that the driver of any vehicle must choose the safe speed of his movement. It is better to clearly understand what will be the stopping distance, than to look after how it is measured.
