The PSS: From Flat Maps to Layered Perspectives - the contribution of

the Airport Metropolis PlanningSupport System (PSS) to sub-

regional planning in the Brisbane Airport case environment

Airport Metropolis Project

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

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

Background

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

Sub-models in PSS

Model Description Tools

Development suitability model

A weighted multi-criteria analysis framework was implemented to produce a polygon feature class that indicates where certain types of development should occur given constraints as inputs.

Combined ArcGIS model builder and CommunityViz dynamic attribute functions

Allocation Model

Based on the different urban forms derived from different scenarios and suitability analysis, the residential population and employment growth are allocated at the different polygon feature level.

Building build-out model

The existing CommunityViz Build-Out tool is usedto visualise the amount and location of bulding develop given the different stakeholder policies. The floor space ratios used are obtained from a survey of existing airport developments.

Built-in CommunityViz function

Transportation model

The transportation model is a simplified version of the Brisbane Strategic Transport Model (BSTM) and Brisbane Strategic Transport Multi-modal Model (BSTMM) at the SEQ level. Brisbane City 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.

VISUM and EMME3 software development kit (Python)

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.

Developed in Excel spreadsheet environment

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
