Abstract

fetched live from OpenAlex

This study aims to analyze the travel behavior changes due to medium-term disruption on public transit networks by using smart card data, as a potential substitute to before-after surveys. The case studies are metro station closures in Montreal, Canada. The study examines the effects of the closures at the aggregate and disaggregate levels, in order to examine the travel pattern changes due to the presented disruption event. The study shows that even a medium-term disruption could have long-term impact on the travel patterns of frequent users of the impacted infrastructure. This study presents a first attempt to use passive data for analyzing the impacts of public transit service disruption on transit customers’ behavior in Montreal. Several limitations and some of the ongoing and future research topics to address the limitations are also discussed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
