4.3 Traffic Distribution

The assumed distribution of trips generated by the site is determined based upon the
anticipated arrival / departure split and the origin / destination split of trips.

4.3.1. Arrival / Departure Split

For the purposes of this study, it has been assumed that the Serviced Apartments,
Independent Living Units, Apartments and visitors to the Aged Care facility have the
following arrival /departure splits.

" 20% arrivals / 80% departures during the AM peak period; and
* 80% arrivals / 20% departures during the PM peak period.

4.3.2 Origin / Destination Split

The distribution of site generated traffic, or the assignment to the surrounding road network,
has been assumed based upon an understanding of the nature of the proposed
development, the surrounding road network, and local residential catchments. The following
assumptions were made accordingly:

* 60% of trips generated will access the site from the north via Ben Lexcen Drive;
* 15% of trips generated will access the site from the east via Lipton Street; and
= 25% of trips generated will access the site from the south via Ben Lexcen Drive.

In addition to the above, it has been further assumed that of the 60% traffic accessing the
site from the north:

" 6% will access the site via Girraween Court:
* 11% will access the site via Heathland Drive; and
= 43% will access the site via Ben Lexcen Drive further to the north.

The resulting volumes are shown in Appendix B.
