Typical left-hand motorway road layout in Ireland and South Africa Divided median strip on a boulevard in Huizhou, China. A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways.
Traffic islands can be used to reduce the speed of cars driving through, [1] or to provide a central refuge to pedestrians crossing the road. When traffic islands are longer, they are instead called traffic medians, a strip in the middle of a road, serving the divider function over a much longer distance.

A driving range is a facility or area where golfers can practice their golf swing. It can also be a recreational activity itself for amateur golfers or when enough time for a full game is not available. Many golf courses have a driving range attached and they are also found as stand-alone facilities, especially in urban areas. They are ...
Traffic barrier with a pedestrian guardrail behind it. Traffic barriers (known in North America as guardrails or guard rails, [1] in Britain as crash barriers, [2] and in auto racing as Armco barriers [3]) keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains ...
The median of a symmetric distribution which possesses a mean μ also takes the value μ. The median of a normal distribution with mean μ and variance σ 2 is μ. In fact, for a normal distribution, mean = median = mode. The median of a uniform distribution in the interval [a, b] is (a + b) / 2, which is also the mean.
the arithmetic mean of data values after a certain number or proportion of the highest and lowest data values have been discarded. Interquartile mean a truncated mean based on data within the interquartile range. Midrange the arithmetic mean of the maximum and minimum values of a data set. Midhinge the arithmetic mean of the first and third ...
If the mean =, the first factor is 1, and the Fourier transform is, apart from a constant factor, a normal density on the frequency domain, with mean 0 and variance /. In particular, the standard normal distribution φ {\textstyle \varphi } is an eigenfunction of the Fourier transform.
A golf simulator allows golf to be played on a graphically or photographically simulated driving range or golf course, usually in an indoor setting. In some cases, based on the location of the sensing devices, it is now possible to capture data on both ball and club for most accurate speed and directional information, and simulated ball flight ...
