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. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas.
The greatest risk reduction in terms of head-on collision comes through the separation of oncoming traffic, also known as median separation or median treatment, which can reduce road collisions in the order of 70%. [6] Indeed, both Ireland and Sweden have undertaken large programmes of safety fencing on 2+1 roads.
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 median of a Cauchy distribution with location parameter x 0 and scale parameter y is x 0, the location parameter.
Highway 401 in Ontario, Canada, has an AADT of over 450,000 in some sections of Toronto. [3] One of the most important uses of AADT is for determining funding for the maintenance and improvement of highways. In the United States, the amount of federal funding a state will receive is related to the total traffic measured across its highway network.

The median and mean age of automobiles has steadily increased since 1969. In 2007, the overall median age for automobiles was 9.4 years, a significant increase over 1990 when the median age of vehicles in operation in the US was 6.5 years and 1969 when the mean age for automobiles was 5.1 years.

Letter writers call for median barriers on I-95 and offer strong opinions on upcoming elections.
The highway dimension is a graph parameter modelling transportation networks, such as road networks or public transportation networks. It was first formally defined by Abraham et al. [1] based on the observation by Bast et al. [2] [3] that any road network has a sparse set of "transit nodes", such that driving from a point A to a sufficiently far away point B along the shortest route will ...
