Abstract
Although motorcycles are the main mode of transportation in many megacities in developing countries, very little research has been conducted on motorcycle operations and related issues. This paper addresses (1) the empirical analysis of the current status of motorcycle ownership and utilization in Ho Chi Minh City, (2) the estimation of the number of motorcycles used in this city, and (3) the analysis and modeling of different transportation policy scenarios. For (1) and (2), the survey results indicate that on average motorcycle ownership (2.33 motorcycles) is higher than that of working-age people in a family (2.29 people). The total number of motorcycles operating in Ho Chi Minh City is estimated to be almost 2 million fewer than that of registered motorcycles. For (3), the results show that each proposed scenario has its own advantage. The demand management policy, which involves either reducing demand via ride sharing or reducing the number of working days per fortnight to 9, is found to be the only single policy that results in little to no adverse impact on total vehicle trips, emissions, fuel consumption, or revenue.

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
