Equal 5-year periods · 2020 excluded · Stats normalized for fair comparisonCatastrophic Post-COVID KSI Surge
+144.5%
KSI rate surged from 12.5% to 30.56% — a 144.5% increase. One of the highest post-COVID surges in Contra Costa County. Urgent systemic intervention required.
Speed: #1 Cause of Crashes & KSI
8.7% → 66.7%
Unsafe Speed is the #1 PCF in Pinole with 26 crashes. Speed KSI rate: 8.7% (era A) → 66.7% (era B). Physical calming, feedback signs, and road diet evaluation are the priority responses.
APPIAN WY: Persistent Hotspot
2 → 2 KSI
APPIAN WY is the #1 HIN corridor with 4 total KSI (0 fatal). Remains city's highest-risk corridor.
HIN: Concentrated Risk
3 new corridors
3 new corridors emerged in 2021–25 not present in 2015–19. 3 corridors persist across both eras. Concentrated risk — targeted corridor investment is efficient.
Alcohol: Persistent Risk
11.8% → 75.0%
Alcohol KSI rate rose from 11.8% to 75.0%. At 75.0%, alcohol crashes remain 1.4× more deadly than non-alcohol. DUI enforcement must intensify.
Pedestrian KSI Rate Rising
22.2% → 50.0%
Pedestrian KSI rate: 50.0% era B. 40.0% of ped crashes in dark conditions — LED lighting and RRFB crossings are the priority response.
Dark KSI Surging
10.3% → 46.2%
Dark-condition KSI rate surged: 10.3% → 46.2%. 42 dark crashes, 9 KSI. LED intersection lighting and retroreflective backplates deliver the highest BCR return.
Volume vs Severity
14/yr → 7/yr
Crash volume: 14/yr (era A) → 7/yr (era B). Volume fell but KSI rate surged — severity crisis, not a volume crisis.
Top Intersection: APPIAN WY & FITZGERALD DR
1 KSI
APPIAN WY & FITZGERALD DR — 1 KSI (0 fatal), 3 crashes. Era A: 1 KSI → Era B: 0 KSI. Targeted intersection capital recommended.
