Decision Support Tool for Sustainable Urban
Development
AIMS

• Briefly outline sustainable urban development
• Outline contemporary urban planning
• Present principles of decision support tools
• Consider decisions to support
• Present D.S.T. that we intend to develop

Sustainable Urban Development
Sustainable Development

• Sustainable development is development that
  meets the needs of the present without
  compromising the ability of future generations to
  meet their own needs.

• World Commission on Environment and Development
  (1987)
• (the 'Brundtland' Report)

4
Sustainable Urban Development

• Greenbelt vs Brownfield
• Greenbelt Undeveloped virgin land/soil
• Brownfield Developed land/soil
• ? Greenbelt not sustainable
• ? Brownfield continual re-use

Management! Urban Planning
5
Urban Planning

• Current Practice
• Concentrated on Objectives
• Alternative strategies assessed
• Optimum strategy implemented
• Strategy continually assessed and reviewed

Continual Iterative Process to Produce Desired
Development Objectives
6
Urban Planning Structure and Local plans

• Structure Plan (Strategy)
• 10-15 years
• Written statement of general development and use
• Conservation/Physical Environment/Traffic
• Local Plan
• Prepared by every local authority
• Fill in details of the structure plan

• Scotland
• 32 Unitary Authorities
• 17 Structure Plan Areas

Urban Planning
Continual Iterative Process to Produce Desired
Development Objectives

• Zoning
• Districts for specified uses
• e.g. Apartments, Retail, Industry
• ? (social, economic, political)

D.S.T. Decision Support Tool

Decision Support Tool

• Definition
• Computer based system
• That help decision makers
• Confront ill structured problems
• Through direct interaction
• With data and analysis models

• Sprague and Carlson (1992)

10
What Decisions to Support?

• Zonation
• Developer
• Locate land
• Site Survey
• Soil survey
• Remediate or pull out?

11
What Decisions to Support ?

• Environmental Zonation

• Reduced Cost !

Increase Revenue!
12
What Decisions to Support ? (Contd)

• Planning Restrictions
• Dimopoulos et al
• Lead Concentrations
• Neural Network Modelling
• Volume of Traffic, Height of Buildings, Distance
  from Road
• Dominant Factor - Height of Buildings

Choice of D.S.T.
Geographic Information System (G.I.S.)
14
Choice of D.S.T.

• Geographic Information Systems (G.I.S.)
• Collect, store and retrieve information based on
  its spatial location
• Identify locations within a targeted environment,
  which meet specific criteria.
• Explore relationships among data sets within that
  environment
• Analyse the related data spatially as an aid to
  making decisions about the environment
• Facilitate selecting and passing data to
  application-specific analytical models capable of
  assessing the impact of alternatives on the
  chosen environment.
• Display the selected environment both graphically
  and numerically either before or after analysis.

Decision Support Tool for Sustainable Urban
Development Summary

• Briefly Defined Sustainable Urban Development
• Linked S.U.D. to role of town/urban planners
• Defined Decision Support Tool
• Provided examples of decisions that could be
  supported
• Outlined a suitable D.S.T. (G.I.S.) and
  described its properties
