An independent, GTFS-based corridor study of Worcester Regional Transit Authority scheduled service. Study dates 2026-06-26 → 2026-07-31 → 2026-08-21. The three analysis dates—June 26, July 31, and August 21, 2026—were selected as comparable Friday service days to support a like-for-like longitudinal assessment of scheduled corridor headway regularity, service gaps, and potential bunching. GTFS calendar and calendar-exception records are validated for each date before comparison.
