What is the Meaning & Definition of intersection

The concept of intersection is used in way extended in our language with two senses.
On the one hand, in the field of geometry it is used to designate that common point where the two lines are cut. Also to indicate the meeting between two lines, two planes or two objects intersecting each other.
But without a doubt it is at road level where more we used it at the end, but we can not ignore that use derived, resulting directly reference that holds in the geometry.
Basically, a road intersection is the intersection of two or more streets, roads. Its main function is that those who pass them can connect with other routes and thus to reach the destination.
The road design typically has two types of intersections or intersections, level, such is the case of streets or roads that suddenly at a given point cut but at the same level.
And on the other hand there are those who know overpass intersections or overpass, which as its name anticipates it us is the adaptation of two or more crosses to height, i.e. come the the crossover point are not roads because they are at different levels, clear examples are the tunnels, bridges or viaducts.
It should be noted that at level intersections tend to be more problems at the level of potential for accidents than those that are not level and therefore is that in some who happen to be historically complicated, municipalities, decide to carry out works such as level crossings to remedy these disadvantages which tend to be the life of the people.
On the other part and attending to the danger that represent almost all intersections is that they should exist in most traffic lights and these must add to them signs anticipating his arrival or presence, the most common and recognized worldwide include: STOP / PARE, CEDA EL PASO ALTO, among others.
It is also important to indicate that traffic accidents are one of the leading causes of death in the world, then, more respect the indications, both from the side of motorists and by pedestrians, we will have streets, roads, pathways, routes, safer for everyone.
