Abstract
This study formulates three fundamental extensions of the standard optimal road use analysis: (1) considering fuel and emissions as variable costs, (2) maximizing the social welfare inside and outside the congestion zone simultaneously, and (3) accounting for time-of-day travel demand variations. Using Fresno, California, as case study, I found several interesting results. (1) Although emissions costs are small relative to other variable travel costs, their impacts on the analysis are significant, especially during off-peak periods; for example, in the case study doubling emissions costs triples the optimal (although relatively small) welfare gain from a congestion charge. (2) Without spillover effects consideration, the analysis overestimates the optimal toll rate significantly and can even lead to a total social welfare loss, relative to no-charge conditions. (3) Policymakers should avoid applying a flat daily charge, which can even reduce system performance in off-peak hours.

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
