Comparative Agency Study

Massachusetts Corridor Coordination Benchmark

Which system is better coordinated? All three agencies are evaluated with identical corridor, headway and bunching definitions so comparisons are methodologically consistent. Study window: 2026-06-26 · 2026-07-31 · 2026-08-21.

Comparison unavailable — equivalent analysis periods required. Rankings are published only once WRTA, PVTA and LRTA have published analysis runs covering the same dates, periods and directions.

Research fairness note. This lab does not describe any agency as bad, worst or failing. Findings are expressed in neutral research terminology: higher scheduled bunching, lower regularity, greater headway variability, more frequent long gaps, stronger schedule coordination or better corridor regularity.
