Abstract

fetched live from OpenAlex

A transit network, visualized as a graph, can be evaluated using indicators such as connectivity, coverage, directness, and complexity, among others, based on the relationships between network elements. This study focuses on the analysis of interconnected and operationally complicated bus networks, a shortcoming of existing approaches tailored to simpler, metro networks. A new procedure is proposed for drawing bus networks as graphs, by disaggregating them into sub-networks at the traffic analysis zone level. As well, improved network connectivity indicators are proposed which incorporate the influence of bus operational characteristics. The effect of bus route transfers is analyzed by introducing intermediate walking transfer edges. The contribution of this research will provide transit agencies with quantitative measures to analyze the network characteristics and the related operational attributes at a zonal sub-network level across the agency’s coverage area. The proposed methodology was demonstrated by applying it to the Greater Vancouver Regional District public transportation system.

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.
