Braking distance is not to be confused with stopping sight distance. The latter is a road alignment visibility standard that provides motorists driving at or below the design speed an assured clear distance ahead (ACDA) which exceeds a safety factor distance that would be required by a slightly or nearly negligent driver to stop under a worst ...
Odometer. An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two ( electromechanical ). The noun derives from ancient Greek ὁδόμετρον, hodómetron, from ὁδός, hodós ("path" or "gateway") and ...
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]

This list of countries by traffic-related death rate shows the annual number of road fatalities per capita per year, per number of motor vehicles, and per vehicle-km in some countries in the year the data was collected. According to the World Health Organization (WHO), road traffic injuries caused an estimated 1.35 million deaths worldwide in ...
Flight length. In aviation, the flight length or flight distance refers to the distance of a flight. Aircraft do not necessarily follow the great-circle distance, but may opt for a longer route due to weather, traffic, to utilise a jet stream, or to refuel. Commercial flights are often categorized into long-, medium- or short-haul by commercial ...
The kilometre, a unit of length, first appeared in English in 1810, [ 9] and the compound unit of speed "kilometers per hour" was in use in the US by 1866. [ 10] ". Kilometres per hour" did not begin to be abbreviated in print until many years later, with several different abbreviations existing near-contemporaneously. 1903: "KMph."
0 to 60 mph. The time it takes a vehicle to accelerate from 0 to 60 miles per hour (97 km/h or 27 m/s ), often said as just " zero to sixty " or " nought to sixty ", is a commonly used performance measure for automotive acceleration in the United States and the United Kingdom. In the rest of the world, 0 to 100 km/h (0 to 62.1 mph) is used.
