Articulated trucks

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 can be linked to a trailer.

Commodity carried

The publication of commodities carried is based on the 10 sectional groupings of the Australian Transport Freight Commodity Classification (ATFCC) and Australian Pack Classification (APC), (cat. no. 1210.0).

Dangerous goods

Those goods classified as dangerous or hazardous based on the Australian Dangerous Goods Code, 5th ed., AGPS, Canberra.

Destination

Represents the point to which goods were delivered.

Freight

Includes all goods and materials transported except 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.

Imputation

The replacement of either missing or invalid data with accepted data. Normally done in accordance with predetermined decision rules and often combined with editing.

Imputation class

The sample is divided into homogeneous, non-overlapping groups based on the characteristics of the sample. This aids in selecting donor records for the process of imputation.

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 trailer towing vehicles such as articulated trucks.

Gross Vehicle Mass (GVM)

Tare weight (i.e. unladen weight) of the motor vehicle plus its maximum carrying capacity.

Method of transport

Identifies whether the commodity was moved in bulk (solid or liquid), was containerised or moved as 'other' freight.

Mode of transport

Identifies whether the movement was made by road (articulated vehicles only), rail, sea or air.

New motor vehicle registrations

Registrations of new vehicles legally registered for the first time.

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).

Origin

Represents the point from which goods were picked up.

Prime account

An agreement to move freight made between the original consignor of the freight and the transport operator.

Prime movers

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.

Own account

Freight that is owned and transported by the same legal entity.

Refrigerated

Identifies those goods carried which require insulation, chilling or freezing during transportation.

Road

Includes all roads, public and private, in all states and Territories of Australia, on which freight has been carried.

Rigid trucks

Motor vehicles exceeding 3.5 tonnes GVM, constructed with a load carrying area, including rigid trucks with a tow bar, draw bar or other non-articulated coupling on the rear of the vehicle.

RSE

Relative standard error. The standard error expressed as a percentage of the estimate to which it refers.

Standard error

A measure of the likely difference in the estimates resulting from not including all articulated vehicles in the road component of the survey.

state/territory of registration

The state or territory motor registry at which a vehicle is registered.

Stratification

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.

Tonne-kilometres

Total tonne-kilometres is the number of tonnes moved multiplied by the distance travelled in kilometres (e.g. 25 tonnes of freight moved a distance of 100 kilometres is 2,500 tonne-kilometres).

Tonnes carried

Total tonnes carried is the total weight of goods and freight carried during the survey period. The estimate of annual 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).

Trip

A trip is a journey made by a prime mover (with or without trailer/s attached) from one location to another.
