# BART Tests Free Live Visual Interpreters for Blind and Low-Vision Riders
Through Jan. 3, Bay Area transit riders can call a trained Aira agent at no cost for help with any BART trip, from their front door to their destination

SAN FRANCISCO — Bay Area Rapid Transit (BART) is running a pilot that gives blind and low-vision riders free on-demand help from live, professionally trained visual interpreters. The service, from the company Aira, began Tuesday, Oct. 6, 2026, and runs through Sunday, Jan. 3, the agency said.
Riders use the free Aira Explorer smartphone app to start a video call. The interpreter sees through the rider's phone camera and can describe the surroundings, read signs and text, and help find a station entrance, fare gates and ticket machines, identify the right platform, and board the correct train. Aira normally charges by the minute. During the pilot, BART is covering the cost of any call tied to a BART trip, "from a rider's front door all the way to their destination," according to the agency's announcement. The pilot is funded by a Federal Transit Administration grant.
"Blind and low vision riders have told us that navigating to and through our stations can be a real challenge, especially finding fare gates and other key features," Ryan Greene-Roesel, director of BART Customer Access and Accessibility, said in the announcement. "This pilot gives us a chance to test whether a live, on-demand interpreter can make those everyday trips easier."
How it works
BART lays out the steps:
- Download the free Aira Explorer app from the Apple App Store or Google Play.
- Create an account and allow camera, microphone and GPS access so the interpreter can help.
- On the home screen, tap Browse Access Offers, search for BART, and the offer is applied to your next call.
- Tap "Call an AIRA agent." BART says riders reach a live interpreter in 10 to 15 seconds.
- Tell the interpreter you are making a BART-related trip and point the camera at what you need help with.
The service runs 24 hours a day, seven days a week during the pilot. Riders do not have to be inside a station. A call can cover the walk to the station too. Aira interpreters get basic training on the BART system and can use BART's website and app to answer questions.
The service needs a data connection. BART says free Wi-Fi is available at SFO, West Oakland, 16th St./Mission, 24th St./Mission, Glen Park, Balboa Park, Embarcadero, Civic Center and Powell St. stations, with more coming. Aira support is available from the app menu, at Support@aira.io, or at 1-800-834-1935.
Background: the "last 50 feet" problem
Blind travelers often say the hardest part of transit is not the train ride but everything around it: finding the right entrance on a busy block, locating fare gates in a large concourse, choosing the correct platform, and confirming the arriving train is the right one. Tactile paving, audio announcements and braille signs help when they are present and well maintained, but they do not answer every question in real time.
Remote visual interpretation fills that gap with a person rather than a fixed piece of infrastructure. Aira and similar services have grown over the past decade, and many airports, retailers and universities already sponsor free Aira minutes for visitors. A transit agency paying for door-to-door trips across a whole regional system is a notable step, especially framed as a test of whether to fund it long term.
Analysis: what the pilot gets right, and what to watch
Strengths. The pilot is free during its run, covers the whole trip instead of just the inside of stations, runs 24/7, and needs only a phone most riders already have. That lowers the barriers that often keep blind people from trying a new tool. Having interpreters trained on BART specifically, rather than general-purpose describers, should also make answers faster and more accurate.
Connectivity. Aira depends on video, and video depends on signal. BART lists only nine stations with free Wi-Fi, and underground segments of any transit system can be patchy. Riders without large data plans may face real costs or dropped calls at exactly the wrong moment. How well the service holds up in practice will likely be one of the most useful findings.
Complement, not replacement. A video interpreter does not replace good physical accessibility: working elevators, consistent tactile guidance, accurate audio announcements and trained station staff. The pilot is most valuable if BART treats it as one layer of a broader access strategy and uses what it learns, such as which gates or platforms riders struggle with most, to fix the stations themselves.
AI vs. humans. The pilot launches as AI visual description tools are spreading quickly, including camera-based assistants in phones and smart glasses. Those tools are fast and cheap, but their makers generally warn against relying on them for navigation or safety. A human interpreter can judge context, ask follow-up questions and take responsibility in a way current AI tools cannot. BART's pilot gives it real-world data on the value of a human in the loop.
What's next
BART says it will collect rider feedback and review usage data throughout the pilot to learn how riders use the service, what helps most, and whether it should seek funding to offer something similar in the future. Riders who try it can send feedback through BART Customer Services.
For blind and low-vision travelers elsewhere, including in the Philippines, where Manila and other cities are expanding rail and bus systems, BART's results are worth watching as a model transit agencies could copy or adapt.
The pilot ends Jan. 3, 2027. The Chronicle will report on any evaluation BART publishes.
