In Latin it is where we can establish that the etymological origin of the term intersection is found. Exactly it must be indicated that it derives from the Latin word “intersectio”, which can be translated as “encounter between two lines that intersect one another” and that it is the result of the sum of these lexical components:
-The prefix “inter-”, which is synonymous with “between”.
-The verb “secare”, which is equivalent to “cut”.
-The suffix “-cion”, which is used to indicate “action and effect”.
This is how the meeting or crossing between two or more elements, usually in a linear fashion.
Among the words that can function as synonyms for intersection we find confluence, union, crossroads or bifurcation, among others.
A road intersectionIn this framework, it is created when two or more streets or roads intersect. Thanks to this infrastructure, drivers have the possibility to change lanes or to maintain their address.
Road intersections can develop to level or unevenness. In the first case, it is a resource that implies a greater risk of collision, since all vehicles cross the same place. To minimize the chances of an accident, various kinds of controls and resources are used: warning signs High (Stop or Stop), traffic lights, roundabouts or roundabouts, etc.
It is also important to know that when we talk about level road intersections there are two clearly differentiated types:
-The so-called controlled intersections. These, as their name suggests, have some type of control system to prevent a vehicle collision from occurring. Specifically, in them it is common to find different traffic signs (STOP, Yield, Priority Level Intersection …) or a traffic light.
– Uncontrolled intersections, which are those that do not have control systems of any kind. However, that does not mean that there are a series of rules regarding the movement through them in order to ensure that traffic accidents cannot occur. Specifically, one of the most important rules around these intersections is that the vehicle arriving from the left always has priority.
A uneven intersectioninstead, it assumes that the traffic is segregated 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, the intersection is called 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 intersection of sets, meanwhile, is a operation whose result contains those elements that are common to the initial sets. The intersection of the sets TO and BTo mention one possibility, it will be made up of 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 the sets TO and B will 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”.
