3.5 Trip Generation

The trip generation exercise was split into the two phases of the proposed development. Given
the staged implementation of the development, and the uncertainty in completion of the second
stage of development (i.e. some time prior to 2019), the trip generation was estimated for both
the initial stage (referred to as Stage 1) and the ultimate development (referred to as Stage 2).
While Stage 1 has been assumed to be completed and operational by 2009, the completion of
Stage 2 is planned to be operational before 2019. For this, analysis up to a horizon year of 2019
was undertaken.

Recognising the likely mix of trip generation rates and directional split of traffic generated by the
various types of residential developments within the retirement community, each residential type
was assessed separately, and the resulting sub-totals were summed to estimate a total
development trip generation.

Trip generation rates were based on the NSW Roads and Traffic Authority (RTA)'document.
This data was supplemented with figures from the Institute of Transportation (ITE) Engineers Trip
Generation Manual (7* Edition). The directional distribution split data was taken directly from the
ITE Trip Generation Manual.

The following table summarises the results of the Stage 1 trip generation analysis.
