REVIEWED HIGHWAY ROUTE · 2020–2024
Route 101
Reviewed CHP records for this route inside the current official City boundary, with valid time and coordinates and a same-route alignment match within 50 meters, after overlap screening. This is an incomplete highway subset.
3,791Reported crashes
134KSI crashes
48People killed
94People severely injured
KSI means a crash with at least one person killed or severely injured. People and crashes are different units. Counts describe this dated study population, not risk per trip.

Who was involved?
Involvement does not identify who was injured. A crash may involve more than one road-user type. Unknown records are disclosed separately.
| Road user | Crashes involving mode | KSI crashes involving mode | Mode unknown: all crashes | Mode unknown: KSI crashes |
|---|---|---|---|---|
| pedestrian | 30 | 22 | 0 / 3791 | 0 / 134 |
| bicycle | 2 | 2 | 0 / 3791 | 0 / 134 |

| vehicle occupant | 3742 | 125 | 25 / 3791 | 5 / 134 |
Actual KSI people by mode, with attribution coverage
These totals use verified party/person attribution only. Missing attribution is not zero. The observed person totals do not have complete coverage.

How to read this report
- 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.
- CHP 2024 is provisional. Missing coordinates, route mismatch and unresolved overlaps are excluded; this route count is not the full number of highway crashes.
