Perspectives - the contribution of
the Airport Metropolis Planning
Support System (PSS) to subregional planning in the Brisbane
Airport case environment

Background
National Aviation Policy White Paper
(NAPWP)
• After reviewing issues submitted from
industry
• NAPWP calls for:
Better integration of airport planning
and local planning schemes
Background
Communication between stakeholders is key
• NAPWP calls for:
Planning Coordination Forums
– Promote dialogue between stakeholders
• Airport master plans
• Proposed airport development
• Regional planning initiatives
• Collaborative planning theory approach (Healey,
1997)
• Need a tool to aid decision making within the
Planning Coordination Forums
What is PSS?
• Any geographical information and spatial
modelling system that has been developed to
support public or private planning processes (or
parts thereof) at any defined spatial scale and
within any specific planning context (Geertman
and Stillwell, 2003)
• Missing link between Planners and Geographic
Information Systems (GIS)
Building the Prototype PSS
• Data collection
– User Required Specifications
– ABS (Census Data)
– Airport City Workshops
– SEQ Regional Plan
– City Plan
– Airport Master Plan
– BSTM and BSTMM
• Software selection
– ArcGIS
– CommunityViz
– VISUM and EMME3

Description
Tools
Development
suitability
model
A weighted multi-criteria analysis framework was implemented to Combined ArcGIS model
produce a polygon feature class that indicates where certain types of builder
and
development should occur given constraints as inputs.
CommunityViz dynamic
attribute functions
Allocation
Model
Based on the different urban forms derived from different scenarios Combined ArcGIS model
and suitability analysis, the residential population and employment builder
and
growth are allocated at the different polygon feature level.
CommunityViz dynamic
attribute functions
Building build- The existing CommunityViz Build-Out tool is used Built-in
out model
to visualise the amount and location of bulding develop given the function
different stakeholder policies. The floor space ratios used are
obtained from a survey of existing airport developments.
CommunityViz
Transportation
model
The transportation model is a simplified version of the Brisbane VISUM and EMME3
Strategic Transport Model (BSTM) and Brisbane Strategic Transport software development kit
Multi-modal Model (BSTMM) at the SEQ level. Brisbane City (Python)
Council and Department of Transport and Main Roads originally
developed the BSTM and BSTMM respectively. The models are
modified in a way so that they can be fitted in the PSS.
Economic
Impact model
An Input-output Model that can input employment figures to get
%GVA changes of Australia, Queensland (QLD), South East
Queensland (SEQ) and Brisbane City Council (BCC) area as an
output without doing any further calculations.

Conclusion
•
Empirically and visually compare and communicate
different spatial planning policies - bridge the gap
between federal, state and local planning requirements
•
Ability to express a common planning language and
provide ‘real time’ visual interaction
•
Allow the different stakeholder positions to be
communicated to the broader planning group in factual
terms, thus limiting tensions
