Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it ... 40 feet (12 metres) 30 mph: 75 feet (23 ...
d MT = braking distance, m (ft) V = design speed, km/h (mph) a = deceleration rate, m/s 2 (ft/s 2) Actual braking distances are affected by the vehicle type and condition, the incline of the road, the available traction, and numerous other factors. A deceleration rate of 3.4 m/s 2 (11.2 ft/s 2) is used to determine stopping sight distance. [6]

However, by utilizing real-time data from both companies' hardware, Brembo and Michelin say they can reduce stopping distances by up to 13 feet in a variety of tire and road conditions.
Since kinetic energy increases quadratically with velocity (= /), an object moving at 10 m/s has 100 times as much energy as one of the same mass moving at 1 m/s, and consequently the theoretical braking distance, when braking at the traction limit, is up to 100 times as long. In practice, fast vehicles usually have significant air drag, and ...
The distance "d i" is the sum of the measured limit line setback distance—which is typically regulated by a Manual on Uniform Traffic Control Devices, at often between 4 and 30 feet in the United States [134] [135] [136] —and the crosswalk, parking lane, and road shoulder width.
The braking distance will be approximately 250 m (820 ft) at 100 km/h (62 mph) and 600 m (2,000 ft) at 160 km/h (99 mph). High-speed trains are usually equipped with a magnetic track brake, which can give about 0.3 m/s 2 extra, and give braking distances of about 850 m (2,790 ft) at 200 km/h (120 mph) and 1,900 m (6,200 ft) at 300 km/h (190 mph).
The experiments demonstrated that anti-lock brakes can be of great value to motorcycles, for which skidding is involved in a high proportion of accidents. Stopping distances were reduced in most of the tests compared with locked wheel braking, particularly on slippery surfaces, in which the improvement could be as much as 30%.
