4.     TRIP GENERATION AND DISTRIBUTION

In order to analyse the impact of the development on the existing transport
infrastructure, it is necessary to assess the number of trips likely to be generated to
and from the site and where they are likely to travel. To determine an appropriate rate
to forecast trip generation information has been sought from the Department of Main
Roads’ Road Planning and Design Manual: Chapter 3, Queensland Streets, Austroads
and the RTA Guide to Traffic Generating Developments.


4.1    Trip Generation

The development comprises of a medical centre with 2,470m2 for medical use. The
recommended traffic generation rate for a medical centre in suburban city areas is 13
trips / 100m2 of GFA.

Therefore the total trip generation estimated for the proposed development is 321 trips
during the peak hour.


4.2    Trip Distribution and Assignment

Trip origin and destination for the proposed development has been assessed with
traffic from the development assigned to the transport network. The assignment of
traffic is based on a manual assessment of the likely routes to and from the site. This
takes into account the development’s location in relation to the transport network,
residential subdivisions and local employment centres.

The trip attraction for am/pm peak for the medical centres has been based on 60%
arrivals (193 trips) in the morning peak and 40% departures (128 trips) with the
reverse for the afternoon peak. The expected split is 80% to/from the south and 20%
from the north.

A diagrammatic distribution of the peak hour development generated trips is shown in
Figure 6 below.
