                 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.
                       ƒ    20% arrivals / 80% departures during the AM peak period; and
                       ƒ    80% arrivals / 20% departures during the PM peak period.
                 The application of the above distributions results in the number of arrival and departure trips
                 shown in Table 4.3.1 below

                 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:
                       ƒ    60% of trips generated will access the site from the north via Ben Lexcen Drive;
                       ƒ    15% of trips generated will access the site from the east via Lipton Street; and
                       ƒ    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:
                       ƒ   6% will access the site via Girraween Court;
                       ƒ   11% will access the site via Heathland Drive; and
                       ƒ   43% will access the site via Ben Lexcen Drive further to the north.
                 The resulting volumes are shown in Appendix B.
