The Commute Reality Grid
Every Oahu pocket against every installation, in drive-minutes. Oahu punishes the mainland instinct of picking a neighborhood before checking the drive — start here. Two numbers per cell: free-flow / typical peak.

Each cell: free-flow minutes / typical-peak minutes. Peak sampling is pending, so peak renders as an em-dash (—) until it lands — free-flow with honest methodology beats fake precision.
Methodology. Free-flow drive time between pocket and installation reference coordinates via OSRM public routing (no traffic model), rounded to 5 minutes. Peak bands (peak_min) pending traffic-aware sampling per the family-layer spec windows; render as em-dash until sampled. H-3/H-1 incident variance applies; reference coordinates are pocket/installation centroids, not addresses. Pulled 2026-08-06.
Reference points are centroids, not your address; your mileage will literally vary.
