2. STRUCTURE Aim of the work Literature review on SM and its evaluation Data and methodology Descriptive statistics, Cluster Analysis and SOM NeuralNetwork Results Conclusion and discussion Further research questions 3. AIM OF THE WORKInvestigate the SM strategies atneighbourhoodlevel in 37European sustainableneighbourhoods.Differences and commonalitiesamongthedifferentneighbourhoods, will be stressedthroughout CA and SOM NeuralNetwork. 4. Sustainable mobilityAllows safe basic access and development needs ofindividuals, companies and society for equity within andbetween successive generations (social aspects).Is Affordable, operates fairly and efficiently, offers achoice of transport mode, and supports a competitiveeconomy, as well as balanced regional development(economic aspects).Uses renewable resources and non-renewableresources in a rational way, while minimizing the impacton the use of land and the generation of noise(environmental aspects).(European Union Council of Ministers of Transport, 2001) 5.

Holden (2007)achieve it? 6. SM evaluationIn the literature it is possibile to find many SM indicatorsat 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 andchoice of related indicators in order to create adatabase; 2 step elaborating database indicatorsthroughout Cluster Analysis and SOM NeuralNetwork 8.
