Traffic crash roadway and environmental conditions

The 2024 Final FARS crash and vehicle tables directly provide relation to trafficway, roadway alignment and surface condition, junction/intersection, traffic-control device and functioning, work-zone, light-condition, and crash-recorded atmospheric-condition fields, keyed to ST_CASE and pinned to the U.S. fatal-crash scope and 2024 Final schema/release.

For each keyed, dated, and located police-reported personal-injury collision, the final STATS19 collision file records road type, junction detail and control, pedestrian-crossing context, light, weather, road-surface condition, special conditions at the site, and carriageway hazards. These are primary official recorded-condition fields within Great Britain coverage, pinned to the final 2025 release and 2024-specification mappings; the claim does not infer narrative reconstruction or an ordered event sequence.

For a CASE_ID-selected California crash, TIMS records roadway surface, first and second roadway-condition codes including construction or repair zone, intersection status, traffic-control-device presence and condition, lighting, two weather conditions, named roads, and geocoded location. These are primary police-recorded roadway and environmental facts; deprecated road-type fields and absent ordered sequence are not used to infer unsupported detail. Pin answers to California scope, PROC_DATE, codebook vintage, and final-versus-provisional status.

Crash rows keyed by crash_record_id directly emit reporting-officer determinations for trafficway type, street alignment, intersection relation, traffic-control device and condition, active work-zone status and type, lighting, weather, roadway-surface condition, and road defect. These are crash-recorded roadway and environmental circumstances, not an inferred weather reconstruction. Retain CPD/Chicago scope, coverage boundary, and extraction/metadata timestamp because rows can be amended and no row-level release vintage or code-list version is exposed.

The 2024 CRSS public-use crash and vehicle tables directly record relation to trafficway, roadway alignment and surface condition, junction/intersection, traffic-control device and functioning, work-zone, light-condition, and crash-recorded atmospheric-condition fields for sampled eligible police-reported crashes. Answers remain pinned to CASENUM, U.S. probability-sample coverage, the 2024 coded schema, and 2026-04-01 release; weighted population use requires survey-design fields.
