appraisal? If so, what is <strong>the</strong> magnitude of this boarding<br />

penalty (minutes) and how does it differ between<br />

modes?<br />

Weightings - Describe <strong>the</strong> weightings which have been<br />

used to calculate <strong>the</strong> generalised trip cost<br />

Wait / Access / Egress - What weighting has been<br />

applied to egress time? What is <strong>the</strong> source <strong>for</strong> this?<br />

relation to <strong>the</strong> range of transfer factors, including reporting of <strong>the</strong> BCR at intervals between 0% and<br />

100%.<br />

Fur<strong>the</strong>r detail in relation to transfer/substitution impacts is provided within <strong>the</strong> PwC CBA report at<br />

section 4.5.1.<br />

O<strong>the</strong>r factors such as weightings <strong>for</strong> generalised trip cost and wait/egress etc are not considered<br />

to have a material impact on <strong>the</strong> BCR.<br />

Benefit parameters - List <strong>the</strong> value and source of all<br />

benefit parameters relevant to <strong>the</strong> appraisal. For<br />

example decongestion; Vehicle Operating Costs (<strong>for</strong> all<br />

classes of vehicles); Crash costs etc<br />

related to, dependent upon or potentially influenced by<br />

accounted <strong>for</strong> in <strong>the</strong> BCR.<br />

accessibility of ei<strong>the</strong>r <strong>the</strong> Brisbane or Sunshine Coast <strong>airport</strong>s. The transfer impact included in <strong>the</strong><br />

analysis is intended to capture <strong>the</strong> impact of substituted travel from o<strong>the</strong>r destinations and ports to<br />
