Where the I-95 numbers come from
Counted from NHTSA's Fatality Analysis Reporting System, 2024 Annual Report File: every fatal crash whose road NHTSA filed as I-95 in Connecticut (filed under 7 spellings, such as "I 95 SB MILFORD REST AREA", "I-95", "I-95 NB SERVICE AREA RDWY", "I-95 NB X21 RMP"). Ramps, frontage and service roads are left out. Where two routes share a road, NHTSA files each crash under one of them, so a shared stretch counts on one route only. A fatal crash is one in which someone died within 30 days. Totals in state and news reports for a road usually differ: they include ramps and frontage roads, or count from preliminary reports.
