Abstract

fetched live from OpenAlex

A direct ridership model for Canadian rail rapid transit systems is presented. The goal of the study was to produce a ridership model to evaluate the specific context of Canadian rapid transit: no comprehensive model existed. Data were collected for Canada's five largest cities, including 342 stations with an average weekday ridership of more than 3 million passengers. Using bootstrapped ordinary least squares regression with station boardings as the dependent variable and 44 socio economic, built environment, and system attributes as potential explanatory variables, which were chosen after a review of the direct ridership model literature, the study yielded one model with an adjusted R 2 value of .8033. The results are similar to those of models constructed in the United States with respect to densities, land uses, and station amenities, and socioeconomic variables do not appear to be significant. The absence of socioeconomic variables in the final model indicates that planners and policy makers have significant scope to exert influence over transit use through land use planning, design, and service features.

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.
