Within the normal mode of transport operations, the tonnage transported between the loading and unloading points are taken into account.

Within the collection and distribution mode of transportation, the maximum load reached in any point of the route is taken into account in the survey.

Within the shuttle mode of transportation, the average load that the vehicle carries in one journey, and the number of times per day that the journey is repeated, is taken into account in the survey. When utilizing the results, the average daily load is multiplied by the daily frequency.
