Local Government Area LGA A geographical area under the responsibility of an incorporated local government council or an incorporated indigenous government council. LGAs are a non-ABS Structure of the Australian Statistical Geography Standard (ASGS), and are defined by the Departments of Local Government, or their equivalent in each state or territory. The ABS approximates the officially defined boundaries with aggregations of Mesh Blocks.
Mesh block The smallest geographic unit defined by the ASGS. Mesh blocks can be aggregated to represent many different geographical regions. There are approximately 347,500 mesh blocks in all of Australia.
Mode Method of travel. Reported as single mode, mode combinations or priority mode based on a hierarchy.
Mode share Mode share is estimated for each mode from the number of trips made.
Motorised travel Trips by private vehicle, train, bus, ferry, monorail, light rail and aircraft. Excludes walking and bicycle trips.
Newcastle Region Newcastle Statistical Sub-Division.
New South Wales NSW State of New South Wales.
New South Wales Trains Train operator for rail services beyond metropolitan Sydney.
Non Private Dwellings NPDs Non-private dwellings are establishments which provide a communal type of accommodation. Examples of categories are: Hotel, motel; Boarding house, private hotel; Public hospital (not psychiatric); and Child care institution.
Occupied Private Dwellings OPDs For Census purposes, OPDs are equal to the total number of households, as a Census form is completed for each household from which dwelling information for the household is obtained.
Origin/Destination O/D Matrices with counts of trips between origin and destination pairs, usually at the Travel Zone level
Priority Mode Where more than one mode is used for the trip but output is requested for separate modes, the trip is allocated to the mode with the highest priority. Note that the priority order is slightly different for HTS and JTW
Private vehicle Includes all motorised vehicles such as cars, 4WDs, vans, motorbikes, motor scooters, utes and trucks. Private vehicle trips may be as a driver or passenger.

Station Barrier Counts The number of passengers entering (IN) and exiting (OUT) each train station.
Statistical Area Levels 1-4 ABS geographies that are part of the new ASGS first implemented in the 2011 census.
Statistical Area Level 1 SA1 The second smallest geographic area defined by the ASGS. The SA1 has been designed for use in the Census of Population and Housing as the smallest unit for the processing and the release of Census data.
Statistical Area Level 2 SA2 An area defined in the ASGS and consists of one or more whole SA1s. SA2s are based on officially gazetted State suburbs and localities. In urban areas SA2s largely conform to whole suburbs and combinations of whole suburbs, while in rural areas they define functional zones of social and economic links.
Statistical Area Level 3 SA3 SA3s are built from aggregations of whole SA2 boundaries to represent regions of between approximately 30,000 people and 130,000 people to cover the whole of Australia. SA3 boundaries fit within whole SA4 boundaries.
Statistical Area Level 4 SA4 SA4s are aggregations of whole SA3 boundaries and fit wholly within state and territory boundaries. SA4s are designed to reflect one or more whole labour markets for the release of Labour Force Survey data. SA4s are required to have large populations of over 100,000 people in order to enable accurate labour force survey data to be generated on each SA4.
Statistical Division SD A Statistical Division (SD) is an Australian Standard Geographical Classification (ASGC) defined area used prior to the 2011 Census. They consisted of one or more Statistical Subdivisions (SSDs) and covered, in aggregate, the whole of Australia without gaps or overlaps. They did not cross State or Territory boundaries and were the largest statistical building blocks of states and territories.
Statistical Sub-Division SSD The SSD is an ASGC defined area used prior to the 2011 Census which represented an intermediate level, general purpose, regional type geographic unit. SSDs consisted of one or more Statistical Local Areas (SLAs).

Sydney Strategic Travel Model STM A BTS model used to project travel patterns in Sydney, Newcastle and Wollongong under different land use, transport and pricing scenarios. It can be used to test alternative settlement, employment and transport policies, to identify likely future capacity constraints, or to determine potential usage levels of proposed new transport infrastructure or services.
