Mercer Avenue at 8th Street
Requested action: Conduct a daylight and evening field audit, then return with a scoped visibility and crossing-safety response within 60 days.
Permitted claim
What the evidence supports
The observed report rate at Mercer Avenue at 8th Street is elevated in the stated observation window.
Evidence tracks
Agreement is shown; sources are not blended.
- Community reports 14 privacy-safe reports in the six-month window; close pass and sightline conflicts recur. Measured
- Exposure Aligned bicycle-volume estimate; rate interval remains wide enough to require review. Aligned
- Official outcomes No corridor-scale crash agreement claimed. State FARS context is background only. Context only
Why this corridor
Rate, interval, sample size, and sensitivity review are carried together. Rank alone is not the reason.
Strongest limitation
Reporting participation and route choice may differ across the city. This finding does not establish comparative danger.
What cannot be claimed
Fault, causation, guaranteed treatment benefit, or that one design is proven best.
How change will be measured
Freeze the metric and six-month baseline before action; repeat the same window and publish null or inconclusive results.
