Shenzhen Metro launched an AI guide dog on Saturday to assist visually impaired passengers, marking a global first in rail transit. The device, named Xiaosuan or “Little Garlic,” began trial operations at the Huangmugang transportation hub in Futian district, Guangdong Province. Authorities said the launch demonstrates the growing role of artificial intelligence in enhancing accessibility for people with disabilities.
The AI guide dog integrates advanced technologies, including multi-modal 3D-voxel neural network sensing, indoor and outdoor planning systems, and large visual language models. Consequently, the device can autonomously plan routes, navigate precisely, avoid obstacles, follow tactile paving, and recognize visual cues. Passengers can also issue voice commands to reach designated service points, and the device automatically returns to its docking station afterward.
Shenzhen Metro staff supervised safety tests and on-site inspections, ensuring the AI guide dog met all operational requirements. During the first month, dedicated personnel will accompany visually impaired users for guidance and security. Officials indicated that if the pilot program succeeds, the service will expand to other metro stations across the city.
The initiative coincides with the 12th National Games for Persons with Disabilities, reflecting Shenzhen’s commitment to technology-driven accessibility. “It’s like my eyes — wherever I want to go, it takes me there,” said one visually impaired passenger. Another participant added, “The electronic guide dog is more focused and doesn’t get distracted. I feel more confident while walking.”
Shenzhen Metro highlighted broader improvements to barrier-free infrastructure across the network. All 485 stations now feature full accessibility coverage, and upgrades were implemented at key transportation hubs with high passenger flow. Officials said these enhancements aim to support both the National Games for Persons with Disabilities and the National Special Olympic Games, ensuring safe, efficient mobility for all users.
Experts suggest the AI guide dog could serve as a model for other urban transit systems globally. Analysts said such technology can significantly improve independence and safety for visually impaired passengers while promoting inclusive public transportation. The metro operator also hinted at future integration of similar AI-driven mobility aids in other high-traffic stations nationwide.
Shenzhen Metro’s AI guide dog project signals a transformative approach to urban transit, combining advanced technology with social responsibility to enhance accessibility.
