Official sources and data limitations
- Historical reported crashes are descriptive counts, not a prediction of the next crash or an exposure-adjusted risk rate.
- Crash involvement and the injured person's road-user mode are separate measures. A mode-involved KSI crash can injure someone using another mode.
- Road-user and reported-factor fields have incomplete coverage. Recorded positive counts are lower bounds where classifications are unknown.
- The current municipal boundary and dated road geometry are applied to historical records.
- Rank ties are retained. Small count differences do not establish statistical significance, causation, fault or a road defect.
- City records cover SJPD streets and county expressways; this report does not include CHP highway additions.
- The City source is a dated dynamic snapshot, not certified final.
- Crashes naming these streets but not meeting the source-designated at/related and coordinate rules are excluded from the intersection count.
