From crash pull to countermeasure to written justification — the safety chain, in working order.
Core chain: pull data → summarize → find patterns → pick countermeasures → justify → write. Notes below follow that chain; unlinked items are your fill-as-you-learn list.
Workflow notes: How to Pull Crashes from Signal Four Analytics ★ · How to Summarize 5-Year Crash Data · Countermeasure Selection and CMFs · Traffic Calming Toolbox
- Midblock Crossing Evaluation (RRFB PHB Signal) — STEP matrix logic (speed/lanes/volume) for picking crosswalk vs RRFB vs PHB vs signal vs island vs road diet
- School Zones in Florida — s.316.1895 basics, when zones apply, beacon operation windows, and the plan-review checklist
- Vision Zero and the HIN (Tampa Bay) — what Vision Zero / High Injury Network vocabulary means in local scopes, with Plan Hillsborough links
- KABCO Injury Scale — the K/A/B/C/O codes, officer-assigned error, KABCO vs MAIS, and why severity weighting drives costs and priority
- Crash Rate Calculation — MVMT/MEV formulas, worked example, exposure sources, rate vs frequency vs EB, critical rate
- Safety Funding and Formal Studies (HSIP SS4A RSA) — HSIP and SS4A structure, the 8-step Road Safety Audit, and the EIT’s role Concepts to spawn as encountered:
