Trend
Year-by-year change
The chart will separate complete years from partial coverage so a shorter period is not mistaken for a decline.

Roads and intersections
Rankings are intentionally on hold.
A road can appear dangerous simply because it is long or carries more traffic. We will not publish “most dangerous” rankings until the release can support a clear denominator, stable location matching, and a documented severity method.
Methodology and downloads
Every release should be reproducible.
The methodology records sources, versions, coverage, exclusions, normalization rules, validation checks, and any known limitations. Aggregate CSV downloads appear only when source terms permit redistribution.
