Abstract

fetched live from OpenAlex

Traditionally, transit market research has categorized passengers into two distinct groups: captive riders and choice riders. Market analyses that depend on such broad categories are likely to overlook important details about the needs and desires of their customer base. This study attempts to better understand the complexities of the different groups who take transit by using information from five years of customer satisfaction questionnaires collected by two Canadian transit providers. Employing a series of clustering techniques, the analysis reveals that nine market segments are present across different modes in both transit agencies. Three different overarching groups of transit users are identified based on income and vehicle access: choice users (~69%), captive users (~18%), and captive-by-choice users (~13%). The groups are consistent across transit modes and in different geographical regions and are generalizable enough to be widely applicable as a conceptual framework for segmenting and understanding public transit users.

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.
