ANZLIC unique identifier: ANZAC0602000868
Title: Transport Model (TRANSTEP) Network Nodes, Links and Nodes
Custodian: ACT Planning and Land Authority
Jurisdiction: Australian Capital Territory
Abstract:
Text files with co-ordinates and link information for sections of the arterial and distributor road network in the Canberra urban area
ANZLIC search words:
Spatial domain:
Geographic extent name: AUSTRALIAN CAPITAL TERRITORY - ACT - State or Territory - Australia
Note: The format for each Geographic extent name is: Name - Identifier - Category - Jurisdiction (as appropriate) See GEN Register
Beginning date: 1994-12-31
Ending date: Not Known
Progress: In Progress
Maintenance and update frequency: As required
Access constraints:
None.
Lineage:
Developed in-house for transport modelling
Positional accuracy:
Related to ACT grid. Derived from 1:2500 cadatral maps, with the bottom left corner of map sheet having X, Y coordinates of 1000, 1000
Attribute accuracy:
Link lengths scaled from 1:200 cadastral base maps. Link speeds based on judgements using information on zoned speed and observed speed (in many, but not all, cases). Link capacities based on judgement using AUSTROADS data modified by observed lane volumes on many links
Logical Consistency:
Not Known
Completeness:
Includes all arterial and distributor road links in the Canberra road network, including the base network of additional links assumed for future year forecasting
