traffic generated by Lot 3 was considered in conjunction with the existing and the proposed
development of Lot 1. The resulting trip rates for the total yield are presented in Table 15.

8.6.1.2          Retail (Shopping Centre) Use Drop-in Trips
When considering trips generated by the development, it is important to consider that not all
trips are new to the local road network. Traffic that already exists on the road network should
be discounted to account for the ‘drop-in’ component, which is detailed within Austroads Guide
to Traffic Management Part 12, as follows:
            Diverted drop-in trips: A linked trip from an origin to a destination that has made a
             significant network diversion to use the new development.; and
            Undiverted drop-in trips: A linked trip from an origin to a destination that previously
             passed the development site. It is also referred to as a pass-by trip and the new
             development is an intermediate stop on a trip that is made from an origin to a
             destination.
