City rolls out ADA sidewalk assessment using sidewalk‑scanning robots; staff stresses privacy safeguards
Summary
The city described an ADA self‑assessment and transition plan that will use sidewalk‑scanning robots (referred to as Dax bots) to survey up to 90 miles of public sidewalks; staff said robots will operate only on public right‑of‑way, be field‑overseen and that recorded video is looped by default unless an operator saves a clip.
Michael Howell, the city's ADA coordinator and director of the Tyler Area Metropolitan Planning Organization, briefed the Council on the ADA transition plan and a contracted data‑collection effort using sidewalk‑scanning robots supplied by a subconsultant.
Howell said the self‑assessment is underway and that the robot vendor will deploy roughly six robots that can collectively survey about 12 miles per day and complete the 2–3 week data collection period for the project area. He said staff selected corridors with continuous sidewalks, prioritizing arterial and major collector streets, and that the contract covers analysis of up to 90 miles of sidewalks.
On privacy and operations, Howell said the robots will remain on the public right‑of‑way, will not be sent onto private property, and will be supervised by field staff so they are not completely autonomous. He said onboard video is kept on a five‑minute loop by default and that clips are saved only when an operator elects to do so "if there was just an issue that something had come up and they need to be able to look at that later." Howell added that the data will be stored on a secured server and that a field employee will be available within roughly a 20‑minute drive if issues arise.
When asked about cost, Howell said the ADA assessment and transition plan contract was reported as about $350,000 for the overall contract; he did not specify the exact portion of that sum attributable to the robot data collection. Howell also said private buildings will not be surveyed by the robots as part of this contract.
Why it matters: the project is intended to produce a baseline inventory that will inform the city's ADA transition planning and future capital or maintenance priorities for sidewalks; the use of mobile data‑collection robots accelerates field work but raises routine operational and privacy questions that staff addressed in the presentation.
Council did not record additional action on the item during the meeting; staff said outreach, signage and a QR code will direct the public to project information.
