On-Time Performance (OTP) data for the Long Island Rail Road (LIRR) beginning in 2015. The dataset, hosted by data.ny.gov, measures how frequently trains arrive at their final destination within 5 minutes and 59 seconds of schedule. It includes monthly performance metrics segmented by branch and peak travel periods.
Use Cases
- Analyze seasonal trends in train punctuality using the Month and OTP columns.
- Compare peak-hour service reliability (AM Peak, PM Peak) against Off Peak performance.
- Identify branches with consistently high or low on-time rates using the Branch / Line column.
- Build time-series forecasting models for OTP using historical Month and performance data.
Strengths
- Data collection began in 2015, providing a multi-year time series.
- Performance is segmented by operational periods (AM Peak, Off Peak, PM Peak) and Branch / Line.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
