The Latin word intersectio He arrived in Spanish as intersection . This is the name of meeting or crossing between two or more elements , usually linearly.

A road intersection In this framework, it is created when two or more streets or roads intersect. Thanks to this infrastructure, drivers have the possibility of changing roads or maintaining the address .

Road intersections can develop to level or to unevenness . In the first case it is a resource that implies a greater risk of collision, since all vehicles cross the same site. To minimize the chances of an accident, various kinds of controls and resources are used: signs of Tall (Stop or Stop ), traffic lights, roundabouts or roundabouts , etc.

A uneven intersection instead, it assumes that the traffic it secretes through bridges , tunnels or other structures. In this way, the vehicles circulate at different levels, going up or down depending on the road.

In the field of geometry , it is called the intersection of the point, line, curve, volume or surface that results common to at least two elements. The simplest intersection in the framework of Euclidean geometry occurs when two distinct lines that are not parallel intersect at one point.

The set intersection , meanwhile, is a operation whose result contains those elements that are common to the initial sets. The intersection of the sets TO and B , to mention a possibility, will be formed by the elements that are found simultaneously in both sets.

Suppose the set A It is made up "South American countries" and the set B by “Countries whose name begins with a vowel”; the intersection of sets TO and B present the elements "Argentina", "Ecuador" and "Uruguay", as they are "South American countries" and at the same time “Countries whose name begins with a vowel”.
