Advancing Accessibility in Transportation with Generative AI at the Edge
Public transportation is the backbone of urban mobility, ensuring that people from all walks of life can move efficiently and affordably. However, accessibility remains a challenge for many passengers, particularly those with disabilities. Navigating a transit system without clear auditory or visual guidance can be daunting, and real-time access to transportation information is often inconsistent. Traditional AI-powered solutions, while promising, usually rely on cloud-based systems that introduce latency and dependency on stable internet connections—limitations that can reduce their effectiveness in transit environments.
Edge AI is changing this landscape by enabling real-time, localised AI processing that enhances accessibility, independence, and safety for all passengers. Unlike cloud-based chatbots, Edge AI chatbots operate directly on embedded hardware, allowing instant, reliable communication without needing an internet connection. These chatbots are emerging as a transformative force in transportation, particularly in applications such as smart bus stops, where they assist visually impaired passengers through real-time auditory cues, route guidance, and accessibility information.
Public Transport: The Challenges of Accessibility
Despite advancements in urban mobility, many public transportation systems remain difficult for individuals with disabilities to navigate. Visually impaired passengers often struggle to access real-time transit updates, identify the right bus, or find their way to the correct platform. While modern transit apps offer live tracking, they depend on smartphone access, stable connectivity, and user familiarity with digital tools, which may not always be available to all riders. Another challenge is the lack of consistent auditory navigation at bus stops and transit hubs. Many transportation systems rely on static signage, which does not adequately support individuals who cannot rely on visual cues. Additionally, speech-based announcements often become unintelligible in loud, crowded environments, leaving passengers uncertain about their travel options.
For transportation authorities, deploying AI-driven solutions that can process information in real-time, provide clear auditory feedback, and function independently of internet connectivity has long been challenging. Cloud-based AI systems introduce latency issues, requiring stable connections to process user interactions and generate responses. If connectivity is lost, these systems become ineffective, leaving passengers without the necessary assistance.
The solution lies in Edge AI chatbots, which bring real-time, local AI processing to public transit systems. By embedding AI-powered voice assistants into transit hubs, these systems eliminate dependency on cloud infrastructure, ensuring reliable and continuous operation—even in network-congested environments.

How Edge AI Chatbots Improve Public Transportation Accessibility
Edge AI chatbots provide real-time voice guidance and interactive support at bus stops, train stations, and transit hubs. These systems operate locally, allowing passengers—particularly those with visual impairments—to receive instant updates on bus arrival times, route changes, and platform navigation. Unlike traditional announcement systems, Edge AI chatbots can respond to individual passenger inquiries, offering a customized and accessible travel experience.
For example, an Edge AI chatbot can provide auditory cues at a smart bus stop based on a passenger’s spoken request. A visually impaired passenger can press a physical button or issue a voice command to ask when the next bus will arrive. The chatbot immediately processes the request and delivers an audible response, promptly providing the relevant information. Since all computations occur locally on the device, there is no reliance on cloud-based servers, ensuring that the chatbot functions even during network disruptions.
Another key application is assistance with navigation and orientation. Many visually impaired passengers struggle to locate the correct boarding area, particularly in complex transit hubs. Edge AI chatbots, powered by speech-to-text and text-to-speech capabilities, can provide step-by-step guidance, helping passengers locate bus stops, identify designated accessible areas, and confirm their location within a transit system.
Additionally, Edge AI solutions allow for context-aware voice interactions. If a bus route is delayed or diverted, the chatbot can instantly relay updated information to waiting passengers. Instead of relying on static signage or pre-recorded announcements, these AI-driven assistants adapt dynamically, ensuring that passengers receive the most current travel updates in real time.

How Avnet Silica is Delivering Edge AI Solutions for Transit Accessibility
As public transit systems explore AI-driven accessibility solutions, Avnet Silica is leading the way with its powerful embedded AI hardware and real-time voice-processing technologies. The Avnet Silica Edge GenAI chatbot, designed to operate locally on TRIA System on Modules (SOMs), provides a flexible, modular approach to transit AI deployment.
Avnet Silica’s platform leverages Whisper, an advanced speech-to-text engine that enables chatbots to interpret voice commands accurately, even in noisy transit environments. This ensures that passengers receive accurate responses regardless of background noise, making it ideal for deployment at busy bus stops and train stations.
Complementing Whisper is Piper, a text-to-speech engine that delivers clear, natural-sounding voice output. Unlike generic pre-recorded announcements, Piper ensures that responses are generated dynamically, improving user engagement and making information more accessible.
By processing all AI interactions locally on TRIA SOM hardware, Avnet Silica’s Edge AI chatbot solutions ensure uninterrupted operation, even in areas with poor connectivity. This reliability makes them well-suited for transportation systems that require real-time accessibility support.
Meeting Regulatory Standards and Enhancing Passenger Safety
Beyond improving user experience, Edge AI chatbots also help transit authorities comply with accessibility regulations. The European Accessibility Act (EAA) mandates that public transportation services provide equal access to information and communication tools for individuals with disabilities. Transit systems can meet these requirements by deploying voice-activated, real-time AI assistants while enhancing the overall passenger experience.
Moreover, these AI-driven solutions contribute to passenger safety and independence. Visually impaired riders no longer have to rely solely on other passengers for assistance—they can interact directly with an AI system that provides the information they need in a format tailored to their needs. This promotes a sense of autonomy while ensuring that essential travel details are delivered promptly and reliably.
For urban planners and transportation authorities, integrating Edge AI solutions represents a long-term investment in accessibility and efficiency. These chatbots reduce the burden on station staff, allowing transit employees to focus on more complex passenger needs while AI handles routine inquiries. By offering consistent, round-the-clock support, Edge AI chatbots also improve service availability during off-peak hours, ensuring that accessibility remains a priority at all times.
The Future of AI-Powered Accessibility in Transit
As cities expand their public transportation networks, the role of AI in accessibility will become even more critical. The shift toward localised, real-time AI processing creates new possibilities for personalised, inclusive transit experiences. Future advancements may include smart ticketing systems, AI-driven wayfinding for multi-modal transportation, and enhanced multilingual accessibility features.
Edge AI is not just a technological upgrade—it is a fundamental shift in how public transit systems engage with passengers, ensuring that accessibility is built into the infrastructure itself. As transit authorities and urban planners seek to create more inclusive, efficient, and adaptive transportation networks, Edge AI chatbots will play a central role in shaping the future of mobility.
For those looking to explore the broader impact of Edge AI chatbots across industries, our comprehensive article, Revolutionising Chatbot Interactions, provides an in-depth look at the applications and innovations driving this technology forward.
Now is the time for public transportation leaders to embrace AI-driven accessibility solutions and ensure that transit systems work independently, safely, and seamlessly for everyone.
