Essendon Airport located in Melbourne’s inner north is being redeveloped into a large
commercial precinct incorporating up to 120,000sqm office, retail, warehouse and other
land uses. In addition, the site is situated adjacent to one of Melbourne’s busiest
freeway networks, the Tullamarine Freeway.
Part of the redevelopment of the site included a new off ramp from the Freeway and a new
connection into a congested five legged roundabout.
The existing network geometry was replaced by two closely spaced signalised intersections, one of which consisted of five approaches. Due to the intricacy and complexity of the
intersections,traditional modelling methods were not capable of analysing the future
traffic impact. Therefore Paramics was utilised to assess the operation of the network,
particularly the impact of signal linking,queue length interaction, public transport
demand and vehicle platooning.

The model investigated the operation of the network at the following design periods:
• 2006 (Existing conditions and immediate post development);
• At 2011 (50% of the development being completed and in operation); and
• At 2021 (100% of the development being complete and in operation).
Paramics was very useful in obtaining approval from the state road authority (VicRoads)
and the City of Moonee Valley. It was also valuable in demonstrating the impacts of the
site generated traffic to stakeholders and residents. The vehicles generated from the
development of Essendon Airport were altered to different colours which showed the
proportion of additional vehicles on the road network. It was able to show that the
additional traffic from the new development had a marginal impact
on the existing levels of traffic on the road network.
