H01 — What is TUNES

TUNES = Transit User Noise Experience Survey.

Does

  • Passenger measures noise on ordinary rail journeys (iPhone-first)
  • Optional short perception survey after the trip
  • Publishes a quieter-journey / noise map
  • Publishes an open methodology + versioned dataset (often the more important output)

Does not

  • Replace TfL / Class 1 professional surveys
  • Imply TfL endorsement
  • Claim health “risk scores” or engineering-grade accuracy at foundation stage

Who it helps

Operators / authoritiesRecurring passenger pain points (as signals, not substitutes)

Principles (short)

Open · private by default · auditable · honest about uncertainty · offline-first capture · versioned for reproducibility · London-first portable schema · resistant to false precision
