I built a trail accessibility surveyor that runs with the radio off

Description and use

Trailworthy is an offline mobile web app that lets users record spoken observations while walking a trail, transcribes and classifies them against the ABAAS accessibility standard, and outputs a cited report, streamlining trail accessibility assessments.

Problem

Public trails are rarely surveyed for accessibility compliance because traditional surveys require manual tools and data entry, leading to a lack of actionable reports for parks departments.

Outcome

Trailworthy produces a cited accessibility report from spoken notes, enabling parks departments to identify and address barriers without manual surveying.

Workflow

• 1. At the trailhead, name the trail in the app.
• 2. Walk the trail with the device in airplane mode; the screen stays dark and a single button records spoken notes.
• 3. After the walk, press the develop button to trigger offline transcription and classification.
• 4. The app routes each note to the nearest accessibility criterion, checks measurements against thresholds, and compiles a cited report.
• 5. Review the generated Markdown report and share with relevant stakeholders.

Evidence

Trailworthy makes the field half of that job take no more effort than talking.

The only number the app tracks while you walk is how long your screen stayed off.

Back home you hit develop. Whisper transcribes each note on your device.

It installs as a PWA.
