Research objective

• To study how accessibility in the Randstad can be
  improved by synchronizing
• Networks of passenger mobility
• Activity locations
• ICT services and facilities

3
Supernetworks Levels of integration

• Integration of transport networks for different
  modes
• Links represent transfers between transport modes
• Allow studying
• substitution car by public transport
• improvements interconnectivity
• Integration ICT facilities and transport networks
• Links represent communications over distance
• Allows studying
• Effectiveness of tele-working or tele-shopping
  facilities
• ICT use during traveling

4
Supernetworks Levels of integration, contd

• Integration ICT transport networks activity
  locations
• Links connect the networks with different stages
  of executing an activity program
• Allows studying
• how land-use and transportation system provide
  synergy benefits for executing activity programs
• Integration activity programs of groups of
  individuals
• Interactions between individuals are represented
  as synchronization of paths through a
  supernetwork
• Allows studying
• benefits derived from coupling activities at
  certain times and places of a group of
  individuals
• e.g. finding optimal meeting locations

5
Accessibility analysis

• Develop a database of the Randstad and outer area
• Synthesize a population and linked activity
  agendas
• Determine paths through the supernetwork and
  calculate aggregated costs across path
• This measure takes into account
• Multimodal networks
• Services at locations and nodes (including ICT)
• Activity agendas of travelers (and coupling
  constraints)
• Synchronisation benefits

6
Main research questions

• How can urban systems be modelled at the highest
  level of integration to analyze accessibility?
• To what extent are given supernetwork solutions
  effective given behaviour of the individuals
  involved?
• What kind of governance mechanisms can contribute
  to co-ordination of actors so that supernetwork
  solutions can emerge?
• How can transport systems and urban development
  be designed based on the concept of an effective
  supernetwork for improved accessibility?

Project 1 Modeling supernetworks

• Develop models to
• generate personalized supernetwork
  representations
• find personal paths through a supernetwork
• find synchronized paths for a group users
• Jointly with User project data collection based
  on activity diaries and GPS

8
Project 2 Use of supernetworks

• Develop learning and choice models that take into
  account
• awareness and value of synergies
• costs of thinking
• role and value of information
• Data collection based on travel laboratory
  simulator

9
Project 3 Governance of supernetworks

• Identify, analyse and evaluate mechanisms for
  governance
• make an inventory of mechanisms in other
  countries and policy domains
• formally test new mechanisms in a multi-agent
  system
• validate mechanisms in a laboratory setting with
  representatives of governance actors

10
Project 4 Design of supernetworks

• Develop and test different supernetwork concepts
• Research
• Interviews and workshop with actors
• Two case studies to assess concepts
• At city agglomeration level within Randstad
• At the level of the Randstad at large
• Integrate and disseminate the knowledge generated
  across the projects
• Systematic testing of concepts
• Workshop
