The etymological origin of the term intersection is found in Latin. Exactly, it must be indicated that it derives from the Latin word "intersectio", which can be translated as "meeting between two lines that cut each other" 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 what the meeting or crossing between two or more elements is called, usually in a linear way.
Among the words that can function as synonyms for intersection we find confluence, union, crossroads or bifurcation, among others.
A road intersection , in this framework, is created when two or more streets or roads intersect. Thanks to this infrastructure, drivers have the possibility of changing lanes or maintaining direction .
Road intersections can be developed at grade or grade . In the first case, it is a resource that implies a greater risk of collision, since all vehicles cross at the same place. To minimize the possibilities of accidents, various types of controls and resources are used: Stop signs ( 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 indicates, have some type of control system to prevent vehicle collisions from occurring. Specifically, in them it is common to find different traffic signs (STOP, Yield, Level Intersection with Priority...) 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 circulation through them in order to ensure that traffic accidents cannot occur. Specifically, one of the most important rules that exist around these intersections is that the vehicle arriving from the left always has priority.
A grade-separated intersection , on the other hand, means that traffic is segregated through bridges , tunnels or other structures. In this way, vehicles circulate at different levels, passing above or below depending on the road.
In the field of geometry , the point, line , curve, volume or surface that is common to at least two elements is called an intersection. The simplest intersection within the framework of Euclidean geometry occurs when two different lines that are not parallel intersect at a point.
The intersection of sets , meanwhile, is an operation whose result contains those elements that are common to the initial sets. The intersection of sets A and B , to mention one possibility, will be formed by the elements that are simultaneously in both sets.
Suppose that set A is formed by "South American countries" and set B by "Countries whose name begins with a vowel" ; The intersection of sets A and B will present the elements "Argentina" , "Ecuador" and "Uruguay" , since they are "South American Countries" and at the same time "Countries whose name begins with a vowel" .
