      • A Planning Support System for assessing strategies of local urban planning agencies
      • Stephan Kamps
      • &
      • Cécile Tannier
      • International Conference of Territorial Intelligence
      • Besançon 2008
  • Presentation Outline
    • Research objective
    • Structure of PSS
    • Comparing planning systems
    • Discussion
  • Research objective Structure of PSS Comparing planning systems Discussion Research objective
    • A planning support system, which enables the testing and evaluation of urban planning policies
    • A main feature: modelling the behaviour of actors involved in the spatial planning process
    • The comparison of the planning systems of France, England & The Netherlands, as a foundation for our simulation model
  • Research objective Structure of PSS Comparing planning systems Discussion Construction of a planning support system
    • Planning Support System (PSS) – a Definition
    • Software for testing complex systems
    • Many tools focus on finding optimal solution and/or evaluation of a land use configuration
    • Objective of the proposed Planning Support System
    • Effectiveness of planning strategies
    • Effect of a planning strategy on the change of the spatial structure
    • Planning agencies have relatively little direct influence:
      • Landowners define the land use
      • Private developers and housing corporations develop new housing estates
      • Residents decide where to live, work, etc.
    • Urban planning is divided into two processes
    • How can a change in either plan generation or development control change urban development and bring closer the planning objectives?
    Research objective Structure of PSS Comparing planning systems Discussion Urban planning process Urban Planning Plan Generation Development Control
  • Research objective Structure of PSS Comparing planning systems Discussion Structure of the Planning Support System
  • Research objective Structure of PSS Comparing planning systems Discussion Cellular Model
    • Representation of the spatial structure
    • Objectives of planning agencies relate to the state of the spatial structure
    • Indicators representing the quality of the spatial structure
      • Housing density, housing quality, economic value, etc.
      • Residential occupation
      • Closeness of services, green space, city centre, etc.
    • Relationship with other layers
      • No initiative in the urban development
      • Feedback to the other simulations in the system
      • Restriction to the urban development process
  • Research objective Structure of PSS Comparing planning systems Discussion Structure of the Planning Support System
  • Research objective Structure of PSS Comparing planning systems Discussion Urban Residential Model
    • Representation of residential choices
    • A model previously developed at ThéMA
      • The tendency of residents to move
      • Preferred locations of residents
    • Objectives of planning agencies relate to residential dynamics
      • Welfare of residents
      • Occupation/migration of residents
    • Relationship with other layers
      • Residential dynamics are autonomous
      • Constraints of the spatial structure
      • Planning constraints
  • Research objective Structure of PSS Comparing planning systems Discussion Structure of the Planning Support System
  • Research objective Structure of PSS Comparing planning systems Discussion Multi-Agent Simulation Model
    • Representation of the urban planning dynamics
    • Modelling of both plan generation and development control
    • Urban planning dynamics are modelled using a multi-agent simulation technique
      • Agents simulate the behaviour of planning agencies, developers & corporation, landowners and interest groups
      • Agents act based on their objectives, which are derived from their real world counterparts
      • Agents can't achieve their goals by themselves and depend on cooperation with other agents
    • Relationships with other layers
      • Objectives of planning agency agents are expressed in terms of residential dynamics and quality of the spatial structure
      • Developer agents and corporation agents can actively change the cellular model
  • Research objective Structure of PSS Comparing planning systems Discussion Comparing planning systems
    • Comparison of the planning systems of France, England and the Netherlands
    • Help understand differences and common features
    • Show different approaches of:
      • Planning strategy or policy
      • Availability & usage of planning tools & instruments
      • Contact & relationships with other actors in the planning process
    • Calibration & validation
      • Similar case studies in different countries
      • Testing of English, French & Dutch approach
    • Map out & compare the planning processes
    • Map the steps made by the planning support system
  • Research objective Structure of PSS Comparing planning systems Discussion Discussion
    • Originality of our research
    • Process approach
    • Both plan generation & development control
    • Comparison of the planning systems of France, England & the Netherlands
    • What is next?
    • Development of the Planning Support System
    • Case-Studies
