Key Developments:

• In June 2025, Nagpur launched its Intelligent and Integrated Traffic Management System pilot with AI-powered signals, ANPR cameras, speed radars, and LED message boards at three key junctions. Managed from a centralized command center, the initiative targets a 48% reduction in travel time and a 60% increase in vehicle speeds.
• In June 2025, Ahmedabad Municipal Corporation established an Asset Monetization Cell to commercialize urban assets, like smart city properties and real-time data streams, through PPP partnerships, opening new revenue models from traffic and civic services data
• In February 2025, Toyota is preparing to host the first 100 residents in its £8billion “Woven City” robotics-driven smart city at Mt.?Fuji. Covering 175 acres, the project integrates zero-emission transport, AI-enabled homes, health monitoring, and autonomous vehicles within a fully connected urban environment.

Smart Cities Market Segmentation:

Based on the technology:

• IOT
• Artificial Intelligence and Machine Learning
• Cloud Computing
• Big Data & Analytics
• 5G Networks & Smart City Platforms
• Blockchain for Secure Transactions
• Geospatial Technologies & GIS Mapping
• Augmented Reality (AR) & Virtual Reality (VR)

Internet of Things (IoT) leads market with the largest market share in the smart city segment, owing to its foundational role in enabling real-time data exchange, automation, and interconnectivity across various city functions like transportation, energy management, and public safety. IoT sensors and devices power smart grids, smart lighting, waste management, and traffic control systems, making it indispensable for city digitalization. Its scalability and cost-effectiveness further support widespread deployment. In contrast, Augmented Reality (AR) and Virtual Reality (VR) hold the smallest share, as their usage remains limited to visualization in urban planning and public engagement initiatives.

Based on the components:

• Hardware
• Software
• Service

The hardware segment is currently expected to hold the largest market share, driven by the rapid deployment of physical infrastructure like sensors, smart meters, surveillance systems, IoT devices, and communication networks essential for enabling connected city functions. The rising adoption of smart transportation, smart grids, and intelligent public safety solutions significantly contributes to the demand for hardware components. Governments and municipalities are heavily investing in robust hardware setups to build the foundation for smart ecosystems. Conversely, the service segment accounts for the smallest market share, as service-related growth typically follows infrastructure implementation and software integration stages.

Based on the application:

• Smart Security
• Smart Building
• Smart Transportation
• Smart Governance
• Smart Energy
• Smart Healthcare
• Smart Water Network System
• Smart Education

In this segment, smart transportation holds the largest market share, driven by increasing urbanization and the need to reduce traffic congestion, carbon emissions, and enhance mobility. Integrated traffic management systems, real-time public transport updates, and smart parking solutions are being rapidly adopted in urban areas to streamline commute and logistics. The growing emphasis on sustainable urban mobility and connected vehicle technologies has further propelled this segment’s growth. On the other hand, Smart Education accounts for the smallest market share, as its adoption is still emerging and often secondary to more critical infrastructure and urban utility priorities.

Based on the end user:

• Government and Municipalities
• Residential sector
• Commercial and Industrial

In the smart city market, governments and municipalities hold the largest market share, as they are the primary initiators and implementers of smart city projects. Their investment in infrastructure, like smart governance, public safety, transportation, energy management, and urban planning, significantly drives the market. Public sector funding, regulatory frameworks, and global smart city missions further fuel this dominance. The residential sector accounts for the smallest market share, as adoption here is more fragmented and dependent on broader infrastructure readiness and affordability.
