MTA Subway Wait Assessment: Train Spacing Performance from 2015

MTA Subway Wait Assessment measures the regularity of train spacing during peak hours at selected timepoints on each line. The data is provided by data.ny.gov and was last updated on March 23, 2026. It includes monthly performance metrics for different subway lines, divisions, and day types.

Use Cases

• Analyzing seasonal trends in wait_assessment by month and line for service planning.
• Comparing peak period performance between day_type (e.g., Weekday vs. Weekend) using period and wait_assessment columns.
• Modeling operational consistency by correlating num_timepoints_passing_wait_assessment with num_sched_timepoints for specific divisions.

Strengths

• Provides a long-term time series beginning in 2015 for longitudinal analysis.
• Includes granular breakdowns by line, division, month, and period for detailed comparisons.
• Data is sourced from an official government platform (data.ny.gov).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
