Abstract

fetched live from OpenAlex

Transit agencies that operate streetcars use vehicles of varied sizes and characteristics to accommodate demand and service requirements. While some studies have been conducted on the influence of different bus types on service operations, there is limited research on streetcar types. Therefore, this paper examines the impacts of three different types of streetcar operating in the City of Toronto on passenger service time and running time using statistical models. Field data was collected in July 2017 for three types of streetcars serving the busiest corridor in Toronto. Descriptive statistics and two linear regression models were employed to compare their performance. The analysis results support the use of low-floor vehicles with wider doors as well as larger number of doors. Results also indicate a negative impact of the current stop design on the usage of longer streetcars. This study offers transit agencies new insights into the effects of distinct types of streetcars on door usage, passenger service time, and travel time, which are important components of transit service efficiency and attractiveness.

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.
