2. STRUCTURE
• Aim of the work
• Literature review on SM and its evaluation
• Data and methodology
• Descriptive statistics, Cluster Analysis and SOM Neural
Network
• Results
• Conclusion and discussion
• Further research questions
3. AIM OF THE WORK
Investigate the SM strategies at
neighbourhood level in 37
European sustainable
neighbourhoods.
Differences and commonalities
among the different
neighbourhoods, will be stressed
throughout CA and SOM Neural
Network.
4. Sustainable mobility
•Allows safe basic access and development needs of
individuals, companies and society for equity within and
between successive generations (social aspects).
•Is Affordable, operates fairly and efficiently, offers a
choice of transport mode, and supports a competitive
economy, as well as balanced regional development
(economic aspects).
•Uses renewable resources and non-renewable
resources in a rational way, while minimizing the impact
on the use of land and the generation of noise
(environmental aspects).
(European Union Council of Ministers of Transport, 2001)

6. SM evaluation
In the literature it is possibile to find many SM indicators
at the urban scale (among the others Gilbert 2002,
Gundmundsson 2003, Litman 2003).
It is also easy to find indicators for the assessment of
Sustainability in general, developed by international
institutions (OECD, World Bank, EU, ecc...).
Here the focus is on SM indicators at a neighbourhood
scale.
7. Methodology
• 1° step – identification of SM strategies and
choice of related indicators in order to create a
database;
• 2° step – elaborating database indicators
throughout Cluster Analysis and SOM Neural
Network

28. CONCLUSIONS
• Best north-european performance;
• Best “sustainable mobility” practices are those neighbourhoods which
invested a lot in an omogeneous way on all the indicators, both direct
and indirect;
• Mixitè appears more significant than density and also the presence of
green areas.
• In general citizens’ participation is fundamental
• New technologies don’t appear as the most adopted tool for achieving
sustainable mobility: land use and green attitudes are preferred;
• Context variables don’t explain so much
• Two methods quite “agree”, despite some differences in selecting
elements and grouping them
29. FURTHER RESEARCH
• Further analysis of FINWARE: income and incentives
• GDP: it appears useful to be better analysed
• Direct vs indirect also is an interesting topic
• Quality and type of the variables (discrete and
continuous)
• Further analysis of other context characteristics:
presence of infrastructures
• Freight transport could worth be analysed, because it is
a key factor for achieving a real and complete
sustainable mobility: further analysis on city logistics
• Some case study with analysis of citizen’s satisfaction
