4.         Traffic Volumes

4.1        Current Peak Hour
TTM Data conducted intersection movement surveys at the White Pit Quarry access from 6:00am
to 6:00pm on Friday 18th May 2012. TTM also conducted an intersection movement survey at the
Brickworks access from 7:00-9:00am on the same day.
The peak hours were found to be 7:35-8:35am and 3:20-4:20pm. The results of the survey are
shown below in Figure 4.1. The results of the Westridge Quarry AM survey correlate directly to
the movements at the White Pit Quarry access with a 22% reduction in volumes in both through
movements. This reduction has been taken into account for estimated PM movements at this
Westridge Quarry access intersection with a nominal 1vph applied to all turn movements.
The survey results indicate that the AM / PM peak hour traffic volumes on Lake Macdonald Drive
adjacent to the subject site are in the order of 200vph / 220vph. Truck (i.e. non-car) content on
Lake Macdonald Drive was approximately 4%.
