Abstract
This paper draws on a review prepared for the meeting of the European Conference of Ministers of Transport in May 2006. Four separate studies were considered: reducing CO 2 emissions from transport, accessibility for those with reduced mobility, implementation of sustainable urban travel policies, and road safety. The purpose of this paper is to draw together the common strands related to sustainable transport and to make recommendations for ministers and their advisers. In doing so, it concentrates on the barriers to achieving sustainability and the ways in which they might be overcome. The paper starts by considering definitions of sustainability and the underlying objectives that governments might pursue. It then considers the varying contexts within which these objectives might be pursued. It reviews the policy instruments that might be employed in achieving these objectives and reviews the barriers to their introduction. Finally, it offers a series of recommendations to governments on ways of overcoming those barriers. The issues raised are of concern to international policy makers. To focus discussion, the questions for ministers in the original version have been recast as issues that policy makers may wish to consider in their own contexts.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
