Wayfindr — Co-Designed Open Standard for Audio Wayfinding, Piloted at London Underground's Euston Station

Wayfindr began as an idea from the Youth Forum of the Royal London Society for Blind People (RLSB), developed with the digital studio ustwo. In November 2015 Transport for London and London Underground trialled a prototype smartphone app that used Bluetooth beacons in Euston station to give visually impaired users spoken directions, following an earlier pilot at Pimlico.
The trials were used to draft the Wayfindr Open Standard for audio navigation (distance expression, beacon-identified features, audio clarity, update frequency). The ITU page on the project records approval of the standard by the ITU in March 2017 and later trials in Sydney, Oslo, Barcelona and Venice. A $1m Google.org grant supported three years of work.
Evidence is limited: London Underground's capital programmes director described results as 'promising', but neither source reports participant totals or outcome metrics, and a later software accreditation check and training course were described only as plans. It is best read as a user-led standard-setting process rather than a proven service.
