Edge AI is transforming smart cities by enabling real-time, local data processing that improves efficiency, privacy, and responsiveness. Applications include smart lighting, transport management, and waste detection. Projects by PNY Technologies and partners show reductions in energy use and improved mobility insights, while regulatory-friendly deployment supports data security and scalability.
Urbanisation and digital transformation are reshaping the way cities manage infrastructure, services, and engagement with citizens. One of the most impactful developments in this space is the rise of edge artificial intelligence (edge AI) — a technology that brings data processing closer to the source, enabling faster, more private and more efficient decision-making.
Unlike traditional AI models that rely heavily on cloud computing, edge AI processes information locally. This approach offers several advantages: reduced network load, improved data privacy, enhanced efficiency, and real-time responsiveness — all vital features for modern cities seeking smarter operations.
Why cities are moving towards edge AI
Edge AI’s growing adoption stems from practical, operational challenges faced by local authorities. Bandwidth consumption is one such challenge. Streaming high volumes of data — such as surveillance video — to the cloud for analysis consumes significant network resources. By processing data locally, cities can reduce this burden, especially in areas with limited network infrastructure.
Data privacy is another critical concern. Many urban applications involve processing personally identifiable data, from traffic footage to waste monitoring. Edge AI allows real-time anonymisation, enabling cities to comply with regulations without losing operational visibility.
Efficiency and responsiveness also define the value of edge AI. Real-time decisions — such as adjusting traffic lights based on vehicle flow or identifying violations in public transport — can be triggered instantly without waiting for data to be processed remotely. This level of immediacy is increasingly necessary as cities look to improve public service delivery and infrastructure performance.
As cities globally reimagine their operations through AI, the Businessabc AI Global Summit London 2025 brings together technology leaders, policymakers, innovators and researchers to explore these transformative opportunities. The event will cover topics including smart cities, edge AI, ethical frameworks, digital infrastructure, and industry-led case studies.
Real-world applications: From lighting to transport
Across Europe, several municipalities are already using edge AI to address key urban challenges. A smart lighting project developed by AI Tech, a partner of PNY Technologies, achieved a 40% reduction in energy use by optimising brightness based on real-world conditions such as traffic flow and weather. These systems operate directly at the edge, adjusting light intensity in real time and supporting broader functions like pedestrian analytics, smart waste management, and traffic safety.
In another case, BusPas, a project focused on smart bus stops, demonstrated how edge AI can detect over 80% of bus lane violations using sensors embedded directly in bus stop infrastructure. Beyond enforcement, these systems analyse passenger flow, helping transit operators refine schedules, improve mobility insights, and manage resources more effectively — especially in cities where full data on boarding and exiting patterns is unavailable.
Generative AI and localised city services
Edge AI also supports generative AI applications that are increasingly being adopted for administrative automation and customer service. AI assistants can be deployed locally to help citizens with processes such as permit applications, service requests, and field support. When hosted on municipal servers, these systems ensure full control over data, mitigating concerns around external cloud-based providers and strengthening trust in public technology.
Local deployment also allows for customisation with city-specific knowledge, making generative AI more context-aware and useful to residents. This is particularly beneficial as many local governments face resource constraints and need scalable solutions that do not compromise privacy or compliance.
Addressing challenges: Strategy, infrastructure and ecosystem collaboration
Despite its advantages, edge AI implementation is not without barriers. Many city officials are unfamiliar with the technology or cautious due to regulatory uncertainties. Education is crucial, as is providing clear, real-world examples of value creation. Financial constraints and integration with legacy systems are also concerns, requiring structured deployment planning and long-term strategy alignment.
Technology partnerships play a vital role in successful deployments. Companies like PNY Technologies, working closely with partners like NVIDIA, act not just as distributors but as ecosystem orchestrators. Their role includes matching solutions to a city’s infrastructure, identifying local integrators, ensuring regulatory fit, and facilitating global best practices in local contexts.
Youssef Nadiri, Product and Business Development Manager for Smart Cities & Spaces at PNY Technologies, highlights the importance of local knowledge:
“A successful edge AI project requires a well-structured ecosystem – one that includes solution providers, local integrators, and resellers who understand both the technology and the regulatory landscape of a given city or country.”
Expanding use cases for urban sustainability and mobility
Edge AI is being tested and deployed across various domains:
- Smart waste management: Detects litter, monitors bins, and identifies other visual pollutants such as graffiti.
- Road safety: Identifies rule violations like mobile phone usage while driving or absence of seatbelt use.
- Carpool verification: Uses sensors to detect vehicle occupancy and apply dynamic road pricing or lane access controls.
These applications demonstrate that edge AI goes far beyond cost-saving — it offers cities a data-rich, privacy-conscious, and responsive approach to evolving urban challenges.
