How we measured this
- Records: 511NY accident-class records on the Northern State Parkway in Nassau and Suffolk counties, stored by Long Island Traffic’s 511NY monitor, reported from 12:00 a.m. September 23 through 11:59 p.m. September 29 (Eastern). Queens records are excluded.
- “Crash records” are 511 records titled Crash, Vehicle fire or Overturned vehicle; disabled vehicles, debris and other incidents are counted separately.
- Exit, direction, lane impact and time of day come from each 511 record’s own description and “Reported” time.
- Comparison weeks are the four 7-day periods immediately before this one. Our 511 coverage expanded in June 2026, so no comparison reaches before July 1, 2026.
- State Police figures count Troop L daily media-log entries whose road field names this corridor, by the log’s own category. Names in the log are not used.
- The FARS baseline counts fatal crashes and deaths on this corridor’s Nassau and Suffolk portions from NHTSA’s national files.
Limitations
- A 511 record is not a verified crash: one collision can produce more than one record, and some crashes never reach 511. These are record counts, not crash totals or crash rates.
- Weekly counts this small move a lot by chance; a single week above or below the 4-week average is not evidence of a trend.
- There is no traffic-volume denominator, so these counts cannot say whether the road is more or less dangerous per mile driven.
- Our database does not store when 511 closed a record, so this report gives no clearance times.
- The Troop L log is the State Police’s daily media release; it does not include crashes handled by county or local police.
- FARS covers 2010–2024 only (2024 preliminary) and fatal crashes only; it says nothing about this week.
