Motor vehicles constructed primarily for load carrying, consisting of a prime mover which has no significant load carrying area, but with a turntable device which is linked to a semitrailer.
The publication of commodities carried is based on the 10 sectional groupings of the Australian Transport Freight Commodity Classification (ATFCC), with the addition of Tools of Trade and the Australian Pack Classification (APC), (cat. no. 1210.0).
Those goods classified as dangerous or hazardous based on the Australian Dangerous Goods Code, 7th ed., AGPS, Canberra.
Represents the point to which the trip ended. i.e. the load carried or configuration changed or goods were delivered.
Includes all goods and materials transported excluding freight moved by vehicles of the defence forces and by pipeline. Movements made under prime account, own account and subcontract arrangements were reported in the survey.
The replacement of either missing or invalid data with accepted data. Normally done in accordance with predetermined decision rules and often combined with editing.
Gross Combination Mass (GCM)
Tare weight (i.e. unladen weight) of the motor vehicle and attached trailers, plus their maximum carrying capacity. GCM is the weight measurement used for a prime mover/semitrailer combination, or a rigid truck/trailer combination.
Gross Vehicle Mass (GVM)
Tare weight (i.e. unladen weight) of the motor vehicle plus its maximum carrying capacity.
Distance travelled by rigid trucks and articulated trucks from one destination to another when carrying freight.
Method of transport
Identifies whether the commodity was moved in bulk (solid or liquid), was containerised or moved as 'other' freight.
Non-freight carrying trucks
Specialist motor vehicles or motor vehicles fitted with special purpose equipment, and having little or no goods carrying capacity (e.g. tow trucks).
Represents the point at which a trip started. i.e. the load carried or configuration changed or goods were picked up.
An agreement to move freight made between the original consignor of the freight and the transport operator.
Motor vehicles constructed primarily for towing trailers. Prime movers have no significant load carrying area but are fitted with a turntable for linking to a trailer.
Freight that is owned and transported by the same legal entity.
Identifies those goods carried which require insulation, chilling or freezing during transportation.
Includes all roads, public and private, in all states and territories of Australia, on which freight has been carried.
Motor vehicles exceeding 3.5 tonnes GVM, constructed with a load carrying area. Included are normal rigid trucks with a tow bar, draw bar or other non-articulated coupling on the rear of the vehicle.
Relative standard error (RSE)
The standard error expressed as a percentage of the estimate to which it refers.
Indicates the extent to which an estimate might have varied by chance because only a sample of vehicles was included.
State/territory of registration
The state or territory motor registry at which a vehicle is registered.
Stratification is the process where a population is divided into homogeneous groups called strata that are non-overlapping, and together comprise the whole population. This technique uses auxiliary information to increase the efficiency of a sample design and units are selected independently within each stratum.
Total tonne-kilometres is the aggregation of the number of tonnes moved multiplied by the distance travelled in kilometres for each individual vehicle carrying freight. Note that it is not the aggregation of the total number of tonnes moved by total kilometres travelled by all vehicles carrying freight.
Total tonnes carried is the total weight of goods and freight carried during the survey period. The estimate of total tonnes carried relates to goods and freight uplifted by vehicles and therefore will overstate the actual physical quantity of goods and freight moved during the survey period to the extent that transhipment occurs (i.e. the transfer of goods and freight from one vehicle to another).
A trip is a journey made by a vehicle (with or without trailer/s attached) from one location to another where the load carried or vehicle configuration changes.
Distance travelled by rigid trucks and articulated trucks from one destination to another when not carrying freight.
