Current situation

• Different systems managed by different services
  with heterogenous development levels.
• Spontaneous co-ordination or gradual reforms
  are unfeasible in practice because of the
  rigidities and inerties created in all the
  different systems, specially due to
• the lack of explicit metadata procedures and
• the use of heterogeneous Data Models.
• There is a need for a radical change to create
  a new system which can not be just the addition
  of existing pieces.
• The Spatial Policy Support System of Catalonia
  will be defined with a global top-down approach,
  and implemented with a bottom-up inclusive
  strategy.

User-needs

• Cross-sectorial to assess urban, transport and
  regional policies
• Multi-scale integration
• Useful for mangement (e.g. Road maintenance...)
• Useful for planning (e.g. Road traffic
  forecast...)
• Comprehensive service provision
• information
• forecast
• evaluation
• decision-support
• Cutomised for different user-profiles
• Useful for policy-makers (friendly access to key
  modules)

System-architecture

• Centralised system administration and strict
  metadata protocols
• Single Data Model for the whole system (based on
  GTF extended to cover Urban and Territorial
  aspects explicitely)
• Standard software platform Database management
  (ORACLE) and GIS (Geomedia) as a reference
  platform for information management.
• Specialised modules for advanced analytic tasks,
  forecast and decision-support using the most
  suitable software, and sharing the Data Model and
  exchange formats to guarantee full compatibility
• Highly customised user-interfaces for different
  information management tasks built upon standard
  tools whenever is feasible (Desktop mapping,
  text editors, spreadsheets and multimedia
  software for communication and visualisation
  purposes).

Development and implementation plan
GIS-PTOP

• Development of the Road Policy Support System
• Definition of performance indicators to be
  monitored (2001)
• Definition of the Road Data Model (2001)
• Development of the modules (Maintenance and
  Signalling, Traffic counts, Safety...) (2002)
• Implementation of the system (2002)
• Definition of the Data Model for the whole system
  (2001-2002)
• Development of a prototype for the whole system
  (Electronic Atlas) to facilitate future users
  active participation in the process (2002)
• Future development of the whole system (2003 and
  beyond)

Data Model Questions under study
GIS-PTOP

• How to integrate multi-scale levels?
• Real maps
• Abstract graphs
• How to explicitely include as time-dependent
  events such as accidents, congestion... as well
  as management and strategic policies?
• How to integrate the logics of multi-sectorial
  levels?
• Transport System
• Urban System
• Regional System
• What balance between centralised communication
  procedures and highly de-centralised and
  customised modules can be achieved?

14
How to integrate on-line real data within an
information system having the complex
topologia needed to support trafficmodelling?
15
GeoMedia Data Model based onReal Cartography
and Dynamic Segmentation (GDF-UNETRANS
compatibility?)
16
GTF-NIS Data Model based on abstract graphs and
complex multi-modal transport topologies (Compati
bility with GeoMedia Data Model?)
17
Working hypothesis to be validated...

• A single Data Model for both real maps and
  abstract graphs (which should be GTF since it is
  the more abstract and generalised).
• Two independent databases concerning entities and
  relationships
• Real cartography at 15.000 supported by Dynamic
  Segmentation (Geomedia Transport Data Model,
  UNETRANS, GDF...)
• Abstract graph supported by the Complex Topology
  needed to be linked to traffic forecast models
  (GTF...)
• Specialised routines to capture data attached to
  anyone of these two levels, process it, and
  exchange with the other level based on explicit
  rules (Expert System).
