Equal 5-year periods · 2020 excluded · Stats normalized for fair comparisonFewer Crashes, Far More Deadly
+36.6%
KSI rate rose from 8.22% to 11.23%. Volume fell but each crash is significantly more likely to kill or severely injure. A severity crisis, not a volume crisis.
ROW Violations: Dominant Cause
%
Automobile Right-of-Way is the #1 PCF in Richmond — distinct from most Contra Costa cities. Protected LT phases, LPI, and all-way stops at uncontrolled locations are the targeted solutions.
CUTTING BL: Persistent Hotspot
16 → 1 KSI
CUTTING BL is the #1 HIN corridor with 17 total KSI (4 fatal). Remains city's highest-risk corridor.
HIN: Danger Spreading
13 new corridors
13 new corridors emerged in 2021–25 not present in 2015–19. 20 corridors persist across both eras. Systemic citywide programs needed alongside targeted corridors.
Alcohol: Persistent Risk
14.5% → 19.0%
Alcohol KSI rate rose from 14.5% to 19.0%. At 19.0%, alcohol crashes remain 2.0× more deadly than non-alcohol. DUI enforcement must intensify.
Pedestrian KSI Rate Rising
18.9% → 23.3%
Pedestrian KSI rate: 23.3% era B. 39.7% of ped crashes in dark conditions — LED lighting and RRFB crossings are the priority response.
Dark KSI Surging
13.4% → 18.7%
Dark-condition KSI rate surged: 13.4% → 18.7%. 654 dark crashes, 98 KSI. LED intersection lighting and retroreflective backplates deliver the highest BCR return.
Volume vs Severity
321/yr → 130/yr
Crash volume: 321/yr (era A) → 130/yr (era B). Volume fell but KSI rate surged — severity crisis, not a volume crisis.
Top Intersection: MACDONALD AV & 21ST ST
3 KSI
MACDONALD AV & 21ST ST — 3 KSI (0 fatal), 5 crashes. Era A: 3 KSI → Era B: 0 KSI. Targeted intersection capital recommended.
