This is the movement of a single type of goods from one place of origin, where the goods are loaded, to a destination, where they are unloaded.
According to this definition, the transportation of two different types of goods in the same vehicle is considered to be two different transport operations, even though the vehicle only makes one journey.
Furthermore, each partial loading or unloading constitutes a start or end, respectively, of a transport operation.
Therefore, the results given refer to movements of goods, which do not necessarily coincide with the journeys of the vehicles.
"Empty operations", i.e. journeys made without goods, between a point of unloading and another point of loading, are also included.
