Abstract

fetched live from OpenAlex

A new concept in transit travel surveys, called the driver-assisted bus interview, is proposed. The survey uses data that are passively gathered by smart card automatic fare collection systems on public transit. Its superiority lies in the resolution of the data as well as the continuous geographic and temporal coverage of the network and cardholders. The paper first discusses the quality of survey data. It then describes a totally disaggregate object-oriented approach as a method to understand, validate, correct, and enrich the data. The study uses one month of archived smart card boarding data from a medium-size transit agency. The data go through a validation and correction process that makes use of planned service and cardholders’ historic travel pattern. Trip data not collected by the survey are obtained through enrichment techniques. The anchor points of a cardholder can be inferred from the derived employment status, multiday travel pattern, and a trip-generator database. The procedure that infers trip destination and trip purpose for the student subgroup is explained. Advanced analysis and visualization techniques demonstrate the versatility of the data, which can be scrutinized as a travel demand survey, a special trip generator survey, a resource allocation and consumption survey, and a multiday survey.

Full frame distilled prediction

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.
