Abstract

fetched live from OpenAlex

This report documents successful practices in the United States and Canada, and presents information on efforts employed to achieve optimal bus fleet size and effective spare bus ratios. The objective is to update the findings of TCRP Synthesis 11: System-Specific Spare Bus Ratios, as significant changes have occurred in the transit industry since 1995. This synthesis provides valuable guidance to transit agencies on how various factors may affect optimal fleet size. The intended audience for this synthesis can be bus transit management, operations, and all supporting staffs and stakeholders. A literature review, a survey of selected transit agencies with an 80% response rate, and four case examples report on agency bus fleets with numerous unique attributes, service demands, environmental factors, and maintenance issues.

Full frame distilled prediction

Teacher imitation

Not 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.
