NSW Transport Theme - Traffic Control Device

Please Note
WGS 84 = GDA94 service

This dataset has a spatial reference of [WGS 84 = GDA94] and can NOT be easily consumed into GDA2020 environments. A similar service with a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS84 = GDA2020 environments. In due course, and allowing time for user feedback and testing, it is intended that these original services will adopt the new multiCRS functionally.

Traffic control devices are used to control, calm, slow or impede the movement of traffic. 

Sub types that form this feature class includes:

·     Gate - a structure used to regulate movement associated with road or rail

·     Impediment - a structure generally associated with a road that controls or varies the normal travel of vehicles or       pedestrians.

·     Level Crossing - a place where a road and railway intersect at the same level

·     Toll Booth - a structure on a road which requires the user to pay a toll or fee to use the road

·     Cattle Grid - an open floored structure designed to be crossed by motor vehicles

·     Roundabout.

The notional midpoint of a roundabout that has been constructed to allow smooth integration of traffic. Generally only roundabouts forming a road centreline and associated with Road Segments classified as 'Roundabout' will be identified under this classification.

Accuracy 

The dataset maintains a positional relationship to, and alignment with, the Lot and Property digital datasets. This dataset was captured by digitising the best available cadastral mapping at a variety of scales and accuracies, ranging from 1:500 to 1:250 000 according to the National Mapping Council of Australia, Standards of Map Accuracy (1975). Therefore, the position of the feature instance will be within 0.5mm at map scale for 90% of the well-defined points. That is, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = 25m and 1:100000 = 50m. A program of positional upgrade (accuracy improvement) is currently underway.
