Rush hour is more than a stretch of congested asphalt or a packed subway car — it’s a pulse, a ritual, a daily drama where human rhythms, urban design, and time collide. An “Index of Rush Hour” maps that drama: a way to measure, parse, and narrate the patterns that turn ordinary commutes into something almost elemental.
The highest recorded index of rush hour ever measured was in Istanbul, Turkey (2023) during a snowstorm, hitting an astronomical Index 142 – meaning travel took 14x longer than normal. index of rush hour

07:00–09:00 — Rapid climb into the 50s and 60s as offices open; major corridors hit 75 locally.
09:00–11:00 — Partial recovery into the 30s; late commuters keep variability high.
16:00–18:30 — Second spike, often sharper — evening social patterns and freight overlap, pushing index peaks higher than mornings on some routes.
19:00 onward — Gradual descent back toward single digits. Index of Rush Hour Rush hour is more
