Abstract

fetched live from OpenAlex

There are many different factors that affect the ridership potential of public transit technologies, many of which are difficult to quantify. Some of these effects include reliability, comfort, safety, and accessibility. In addition to these effects, it is often hypothesized that travelers have inherent preferences for certain public transit technologies independent of their actual service characteristics. In light of these uncertainties, the goal of this research is to quantify these technology preferences and to discover whether there are modal biases in the Greater Toronto Area (GTA) that are independent from mode level of service characteristics. This study uses travel survey data to build discrete choice models incorporating transit technology specific variables to quantify existing preferences in the GTA. The results show that a preference for rail (Subway and Streetcar) exists, but the magnitude of this effect cannot be quantified due to difficulties isolating the technology preference from other service characteristics.

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.
