Abstract
Urban transport and the issue of motorisation or 'automobile dependence' have become critical shaping factors in the future sustainability and livability of all cities. This paper provides an overview of a selected group of factors that help define some of the main features of urban transport in metropolitan regions around the world. The aim is to provide decision-makers and policy analysts some basic perspective on where cities in their region sit in a global context. The paper also points to some key policy issues that emerge from the data and which have considerable bearing on issues such as priorities in urban infrastructure development. The data are drawn from the Millennium Cities Database for Sustainable Transport compiled over 3 years by the authors for the International Association of Public Transport (UITP) in Brussels. The database provides data on 100 cities on all continents. Data summarised here represent regional averages from 84 of these fully completed cities in the USA, Australia and New Zealand, Canada, Western Europe, Asia (high and low income areas), Eastern Europe, The Middle East, Latin America, Africa and China.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
