settings of that package. The analysis indicated operation well below capacity with degrees of saturation
as follows (full movement summary output from the analysis is attached at Figures 2 and 3):

2024 Background (with high 3%pa growth rate)         Degree of Saturation
AM peak                                              0.71
PM peak                                              0.56

Using the predictions of traffic generation for the development outlined in our 13 December 2013 report
(conservatively assuming all generated traffic is new traffic, without any discounts for drop-in traffic),
including an allowance for the full number of accommodation units that for part of the existing approval,
predicted 2024 peak hour traffic flows at the Heron Street roundabout with the development fully
operational are as follows:

Capacity analysis of the existing roundabout has been undertaken using the Sidra package, with the
same assumptions as previous. The analysis again indicates operation well below capacity with degrees
of saturation as follows (full movement summary output from the analysis is attached at Figures 4 and 5,
and results of analysis without the development are included in brackets for comparison):
