LIST Transport Segment data is a subset of the LIST Transport Segment data and comprises transport routes with highway status. The subset has been created to provide clarity on ownership of roads (Authority). Metadata for each line is linked to the Transport Segment layer through the Feature Metadata Pointer (FMP) attribute.

The State-owned road network consists of approximately 3500km of road. It is a subset of the broader road network that focuses on connectivity and movement functions at State and regional levels. The State network primarily consist of roads that provide connectivity between cities, major towns, rural catchments and key port and air transport hubs. It is intended to provide a strategic classification for the management and planning of the State's transport system.

The State Road reserve identifies land parcels on which State Roads infrastructure is built or surrounds the road network. These areas are reserved for & used as road corridors. These areas are either described by volume and folio reference, or mapped as a buffer to road centre lines. State Roads reserve areas are routinely zoned under the Tasmanian Planning Scheme State Planning Provisions as 'Utility Zone'.

LIST Transport Segment data comprises transport routes (from those with highway status through to rough bush tracks), vehicular and passenger ferry routes, walking tracks, and railways. Transport Segments are those portions of the above routes and tracks which fall between two Transport Nodes. The data will also include those segments which make up larger roundabouts (ie. with centre island diameter > 10 metres), forks (ramps) with a length exceeding 20 metres, and road connectors which are pseudo features that create artificial (naming) continuity through roundabouts. Driveways both public and private but with a length of less than 50 metres have not been captured in urban areas, except where the properties are internal, or have no road frontage. In rural areas, those considered to be the principal driveways or ones with significance were captured. Metadata for each line is linked to the Transport Segment layer through the Feature Metadata Pointer (FMP) attribute.

Road Geometry measures for the Proclaimed State Road network are contained in this dataset. The measures were collected in 2012 by vehicular instruments by the ARRB Group (Consultants). Instantaneous measures were collected at a ten metre intervals (for prescribed and counter direction) and include: Heights (AHD), Bearing, Grade, Vertical Curvature, Horizontal Curvature, Cross Slope & Geometry Speed. The survey is usually undertaken every three years.

Railway represents a permanent way having one or more rail lines which provide tracks for vehicles. A railway can be heavy rails, light rail, monorail and heavy rail siding, for example a railway, tramway or monorail. This data is held and maintained within the NSW Digital Topographic Database (DTDB) and includes key attributes such as railway name and on-type (e.g onground, onbridge, intunnel etc).
