Introduction Territorial Information Territoriale decision support Decision process
Tools example Socioscope : a diagnosis support tool Choosing bus stop equipment
Some Thoughts on the role of information in the territorial decision support process
Conclusion
Territorial information
Dependence on geographic location Altitude and population density
• likely to change based on its location. Person’s weight, engine’s power
• Do not depend on the place of observation Topological relationships or spatial autocorrelation
Values are generally close if spatially close
Interpretation framework
observation locations
similarity relationships

Territorial decision support
Every decision is at least slighty territorial Decision is social Social is also essentially spatial.
Territorial decision, a decision with a « meaningful » effect on territory
Field of territorial decision support Fuzzy boundaries
Decision support
Rational myth Reality can be summed up with mathematics. Decision can be strictly rational.
Nowadays, a more open approach More attention on stakeholders, on problem
formulation and organisational context A place taking account of different rationalities
• Scientific but also aesthetic, social, ethical

Building decision
Why decision-makers are asking for support ? To improve decision efficiency
• Is it really the best choice ? To be able to decide
• How can I decide ? Is there a good choice ?
And if the decision is territorial ? To… be able to decide !
• Too complex
• Too many conflicts : NIMBY, LULU, and so on

Deciding without information
Why decision-makers are asking for support ? To improve decision efficency To be able to decide
LÉVIS City CID : coordination body Decision about residential project 8 executives
• Urban planning, environment, Safety, Police, etc.
Just to Be able to decide !
Main information
During discussions… Cadastral map
Only documents open on the table Poor information but sufficient Complemented by personal knowledge
Participative design process
Plan for a future residential project
Vacant land belonging to the Université Laval
~ 1000 habitation units
Sixty participants : University employees,
students, neighbouring residents, businesspeople,
City of Québec…
Four steps
Information and discussion : several meetings
Diagnostics and prospects : 1 day workshop
Strategy and choice : 1 day workshop
Design : 2 days charrette
Cartographic indicators (on line)

Dwelling affordability
% of householdsspending more than30% in the renting cost
Cartographics indicators (printed)Dwelling affordability
Outcomes
Low use of indicators Only few consultations on the website Few consultations during workshops
Possible reasons ? Cartographic composition, media (Internet, printed
maps), themes of indicators
All the focus on the consensus buildings Few concerns about the decision efficiency

Conclusion
Territorial decision support Still need theoretical and conceptual research
Fuzzy boundaries
Somes distinctives features Spatial relationships: Interpretation framework
Support to build the decision : complexity and conflicts
Constructivist approach : result is the process
A paradoxical question Do decision-makers really need (additionnal) information ?
What about Territorial Intelligence ?
Much in common Global and systemic approach, participatory
processes, and so on
