What does Circulation Stand for?

Circulation is a term that comes from the Latin circulatio and that refers to the action of circulating (belonging to or relative to the circle or that seems to have no end, since it ends at the same point at which it begins). Par excellence, known as circulation to the traffic on public roads.

The circulation, therefore, is the traffic or vehicular traffic. This vehicular flow determines daily life in large cities since, according to traffic conditions, congestion can be generated that causes the loss of a variable number of hours a day to those who must move by this means. When traffic jams are severe, traffic stops, vehicles cannot move forward.

Depending on the traffic regulations applied to two-way roads, authorities may require that traffic stay on the right or left, to improve the flow of vehicles and reduce the risk of head-on collisions; This organization is known as the sense of circulation, and it is of great importance worldwide. Taking into account the number of residents of the entire planet, approximately 34% drive on the left, while the remaining percentage do so on the right side of the road.

A total of 163 countries rely on driving on the right, which has the following characteristics:

* Oncoming vehicles are located to the left of the driver’s field of vision;
* Left turns must cross oncoming traffic;
* most of the traffic signs are to the right of the roads;
* roundabouts must be circled counterclockwise;
* pedestrians must first look to the left before crossing a two-way street;
* the lane for normal driving and for right turns is the right;
* most of the two- way highways have exits on the right;
*overtaking other vehicles is generally allowed only on the left, although there are exceptions;
* most vehicles have the driver’s seat on the left;
* A right turn is allowed on a red light after coming to a complete stop;
* Roads without crosswalks are advised to pedestrians to walk on the left.

On the other hand, there are 76 countries that require driving on the left, whose characteristics are equivalent to those just described, simply with the directions reversed.

The concept of circulation is also used in economics to name the movement of wealth (money, products, stocks, etc.). In a growing economy, there is more circulation (there is more spending and investment), while in times of recession, circulation is reduced.

Another use of the notion is linked to blood. The blood circulation is the physiological function of human beings and most metazoan animals, consisting of the outflow of blood from the heart through the arteries, its distribution throughout the body (to provide cell substances necessary for its normal functioning) and its return to the heart through the veins.

Some of the most common circulation problems in humans are caused by the accumulation of lipids in the walls of blood vessels, and times of high heat make us more prone to suffer from these types of disorders. A good tip to avoid them is to eat a low-fat diet and not overindulge in salt in meals.

Finally, the circulation, run or run of a newspaper or magazine, is the number of copies that are printed and go on sale. For example: “This newspaper has a circulation of 100,000 copies a day.
