At-grade and grade-separated junctions: practice and explanations
At the satin intersection the roads meet at the same level. At staggered levels they pass at different heights and can be connected by ramps: do not confuse the intersection with a railway level crossing.

True or false?
A grade-separated junction includes roads at different heights.
Italian text
L'intersezione (incrocio) a livelli sfalsati comprende strade situate ad altezze diverse
Answer and explanation
Correct answer: TRUE
In the crossing at staggered levels the roads are located at different heights; any ramps connect them without a normal direct crossing of the flows. It is not a satin crossing and it is not the level crossing between a road and a railway.
True or false?
A grade-separated junction has ramps, overpasses and underpasses to connect roads at different levels.
Italian text

Answer and explanation
Correct answer: TRUE
In the crossing at staggered levels the roads are located at different heights; any ramps connect them without a normal direct crossing of the flows. It is not a satin crossing and it is not the level crossing between a road and a railway.
