Maps
Display the selected location from a range of viewing
levels, the start and end position details for the AADT
Segment and the location of the traffic count site.

Road Section
Is the Gazetted road from which the traffic data is collected. Each
Road Section is given a code, allocated sequentially in Gazettal
Direction. Larger roads are broken down into sections and
identified by an ID code with a suffix for easier data collection and
reporting (eg. 10A, 10B, 10C). Road Sections are then broken
into AADT Segments which are determined by traffic volume.

Segment Site
Is the unique identifier for the traffic count site
representing the traffic flow within the AADT Segment.
