While there is a wealth of information about the need for more sustainable transport, and policies and practices to achieve this, progress in this area varies greatly between countries. There is a common assumption that political and institutional frameworks
can and will implement best-practice policies provided that technical information is available (e.g. through assessments). This is considered to be overly optimistic and lacking in conceptual and empirical sophistication, in particular considering socioeconomic and institutional conditions in many countries. There is a critical difference between a policy’s potential and the extent to which this potential can be realised.
This paper focuses on sustainable transport policies in selected developed and developing countries and testing their transferability. This builds on the SOLUTIONS project (; using the project’s concept and objectives, and reports on progress made in the focus regions of Europe, Asia, Latin America and the Mediterranean.
