How we measured this

• Records: every LIRR alert LIT stored from the MTA’s real-time alert feed between 12:00 a.m. October 9 and 11:59 p.m. October 15 (Eastern).
• An alert thread is one MTA alert and all of its updates. Threads are classed by the most serious wording in any update: suspension, then cancellation, then delay.
• Branch comes from the MTA route in the alert; causes come from keywords in MTA’s own text. Planned-work notices are counted separately.
• Comparison weeks are the four 7-day periods immediately before this one.

Limitations

• This is not an on-time-performance measure. One alert can cover one late train or a whole branch, and the MTA publishes on-time performance separately.
• LIT polls the feed on a schedule, so a short alert posted and withdrawn between polls may be missing, and “first seen” times are LIT’s, not the MTA’s.
• Cause categories rely on the MTA’s wording; alerts that do not name a cause are listed as not stated.
