Introduction 2/7
  • SIM-UK
  • Origins in March 2005
  • Group organisation
  • Andy Turner's SIM-UK Web Page
  • Collaborative project
  • Andy Turner's SIM-UK Project Web Page
  • Generating funding proposal phase...

Introduction 3/7
  • GENESIS
  • http//www.geog.leeds.ac.uk/people/a.turner/projec
    ts/GENESIS/
  • Generative e-Social Science for Socio-Spatial
    Simulation
  • A second phase research node of the UK National
    Centre for e-Social Science (NCeSS)
  • Funded by UK Economic and Social Research Council
    (ESRC)
  • Development of Social Simulation models

6
Introduction 4/7
  • NeISS
  • http//www.geog.leeds.ac.uk/people/a.turner/projec
    ts/e-ISS/
  • National e-Infrastructure for Social Simulation
  • Funded by UK Joint Information Systems
    Committee(JISC)
  • Information Environment Programme 2009-11 project
  • To build a generic production quality social
    simulation e-Infrastructure covering the social
    simulation lifecycle
  • Provision of e-Infrastructure that can allow
    others to develop and use Social Simulation models

Introduction 5/7
  • Geographic Agent Based Modelling
  • Geographic
  • About interaction on or near the surface of earth
  • Space-time-attribute
  • It is about people and their environment
  • Agent Based Modelling
  • Distinguishes an Environment and Agents that
    operate within it

8
Introduction 6/7
  • Environment
  • Provides the overall spatial and temporal extent
    and detail
  • Has distributed attributes which are seeded and
    then developed as a result of agent interaction
  • Agents
  • Individual entities that may interact both with
    other agents and with the Environment

9
Introduction 7/7
  • Individual Human Agents
  • Digital demographic representation of a person
  • General characteristics
  • Date of birth
  • Location
  • Memory
  • Current activity
  • Scheduled activites
  • Default behaviours
  • Special characteristics
  • Residential locations
  • Residential locations
  • Preferences
  • ...

10
GENESIS modelling 1/2
  • Demographic/Migration model
  • Daily time step
  • Birth
  • Death
  • Migration type person movements
  • Traffic/Transportation model
  • Second time step
  • Initial focus on travel to work
  • Incorporate travel to school
  • Incorporate other journeys

11
GENESIS modelling 2/2
  • Major issues
  • Visualisation
  • For development and for communicating model
    results
  • Constraining movement
  • Parallelisation
  • Data handling

12
Specifying Agents in GENESIS 1/2
  • Crux Basic idea
  • To get a model running based on available data as
    an initial estimate of peoples movements
  • Allow users to specify Agents movements in the
    models and modify and detail the movements in the
    simulation to reflect what people do/did in
    reality

13
Specifying Agents in GENESIS 2/2
  • Initial seeding the Traffic/Transport model
  • 2001 UK Census data for commuting
  • National Pupil Database (NPD)
  • Pupil Level Annual School Census (PLASC)
  • Other survey data and transportation models that
    suggest levels of movement

14
User control of Agents in GENESIS
  • Issues and concerns
  • What interface?
  • Security and trust
  • How to plug in?
  • Better to focus on getting input from commercial
    organisation data?
  • Travel card (e.g. TFL Oyster)
  • Mobile phone networks
  • Credit card companies

15
Web 2.0 Getting users and Open Development
  • What carrot?
  • Why should users want the application?
  • A game?
  • Some useful function like meeting or avoiding
    people
  • Need for
  • Quality
  • Responsive development
  • Open source to open development

16
Issues and Feedback
  • Starting the main Web 2.0 work
  • What to start with?
  • Considering developing an Open Social Application
  • http//code.google.com/apis/opensocial/
  • Target users of popular social networking tools
    and travel management tools
  • Any questions/comments?
