As digital technologies gain momentum, they are fundamentally transforming the way infrastructure projects are conceived and delivered. Smart electricity meters have crossed the 20 million live data mark as of January 2025, highway toll systems are moving towards multi-lane free flow (MLFF) arrangements, biometric boarding is getting operational across two dozen airports, and unified logistics interfaces such as the Unified Logistics Interface Platform (ULIP) and Open Network for Digital Commerce (ONDC) are evolving into core digital backbones for infrastructure coordination. These achievements rest on a trio of technology pillars. First, artificial intelligence (AI)-driven digital twins give operators live and granular insights into asset performance. Second, expansive internet of things (IoT) sensor webs, running on low-power wide area network, 4G/LTE and soon 6G, feed continuous operational data. Third, interoperable trust layer platforms like ONDC, ULIP and National Logistics Portal Marine standardise data exchange across public and private entities. Together, intelligent algorithms, sensor networks and open digital stacks are becoming as fundamental to infrastructure as steel and concrete, accelerating execution and enabling seamless collaboration across the country’s critical sectors.
A look at the digital solutions deployed across various infrastructure sectors…
Aviation
The advent of 5G connectivity is set to give aviation an unprecedented boost, delivering ultra-low-latency and high bandwidth links that can simultaneously enhance operational efficiency and redefine the passenger experience. Within airports, dense 5G sensor grids and edge computing nodes will automate baggage flows, streamline security checks and optimise turnaround logistics, while continuously feeding predictive maintenance systems that detect equipment faults before they disrupt schedules. On board, next generation in flight networks has started to make streaming and real-time collaboration as effortless in the air as on the ground.
India’s December 2024 decision to permit 5G deployment at airports, following safety trials and altimeter upgrades, is expected to elevate service quality and passenger satisfaction. Previous concerns about altimeter interference had delayed such roll-outs, but controlled tests and new-generation equipment have now cleared the path for telecom operators to install 5G infrastructure across terminals.
Meanwhile, Digi Yatra 2.0 is extending biometric boarding to 24 airports in the coming months, making terminal entry and security clearance seamless, hassle-free and paperless. Additional advancements such as remote air traffic management platforms, sensor fused asset tracking via radio-frequency identification and IoT, point to a comprehensive transformation of India’s aviation landscape.
Ports and shipping
As more ports globally adopt 5G technology, the positive impact is expected to ripple across the entire supply chain, contributing to a more efficient, secure and environmentally sustainable global trade environment. For instance, Tianjin port in China has deployed a 5G‑enabled smart-port system, and since going live, the port reports a 60 per cent reduction in on‑site labour needs, overall cost savings of about 30 per cent and an energy consumption drop of 17 per cent. Furthermore, the integration of advanced encryption protocols and built-in security features with 5G ensures that data transmission at ports remains highly secure, protecting systems against cyber threats and unauthorised access.
Domestically, the Jawaharlal Nehru Port Authority (JNPA) has already achieved full digitisation by embedding automation and advanced tools, such as digital twin technology, into its truck appointment workflow. The next phase of upgrades centres on deploying 5G enabled capabilities while simultaneously strengthening cybersecurity infrastructure to safeguard these connected systems.
However, across India’s 13 major and more than 200 minor ports, which together handle over 90 per cent of the nation’s import-export cargo, persistent issues like terminal congestion, procedural bottlenecks and mounting environmental pressures remain. Digital twin models provide a compelling remedy by allowing operators to create virtual replicas of port assets, test new schedules and anticipate maintenance needs with precision. By simulating operations at facilities such as JNPA or Chennai, for instance, ports can boost throughput, cut costs and reduce trial and error interventions.
Importantly, with sustainability becoming a key priority, digital twins provide actionable insights to monitor and reduce carbon emissions, an essential advantage as India works towards its green goals. In ports like Vizag, for instance, these systems could help streamline coal and iron ore handling to minimise delays and environmental impact. At Kandla, digital models could assist in expansion planning while navigating ecological constraints.
Power
As of June 2025, the Revamped Distribution Sector Scheme has approved the roll-out of 198 million smart electricity meters and awarded contracts for 115 million of them, marking a major leap in India’s advanced metering infrastructure. These devices support multilayered data capture at the consumer, feeder and distribution transformer levels, enabling granular energy accounting and rapid detection of leakages. Alongside metering, power utilities are adopting sophisticated forecasting engines that adjust load predictions to reflect crop cycles, urban demand shifts and renewable energy inflows, while AI-enabled substation automation is providing decentralised control for faster outage recovery and precise voltage regulation. Also, new grid integration tools are synchronising rooftop solar, battery storage and electric vehicle charging with central despatch signals, and interoperable software platforms now consolidate trading, billing, telemetry and demand-side response within a single interface, creating a seamless and data-driven power distribution ecosystem.
Roads
Recent advancements in smart technologies are reshaping India’s road construction sector, making highway safer and more driver friendly. AI is now being deployed to address the network and communication needs of transport infrastructure by using image recognition and machine learning algorithms to detect potholes, cracks, bumps and other hazards. In parallel, IoT is transforming project oversight through sensor and camera networks that provide real-time visibility into construction progress, flag safety risks and monitor the condition of bridges and tunnels to catch maintenance issues before they escalate.
On the operational front, smart roads are leveraging these IoT devices to deliver safer, more efficient journeys that align with national sustainability goals. A notable illustration of the sector’s evolution is the National Highway Authority of India’s (NHAI) MLFF tolling pilot on NH 48 at Pachgaon, which combines the Indian Space Research Organisation’s NavIC L1 band for distance-based charging with Indian automatic number plate recognition cameras and on board FASTag Next tags that store vehicle class and emissions data.
Complementing such initiatives, NHAI has introduced route patrolling vehicles branded as Rajmarg Saathi. These vehicles inspect highway stretches, respond to emergencies and are equipped with dashboard cameras using AI video analytics to identify cracks, potholes, vehicles, pedestrians, road signs and infrastructure assets. Data captured each week is integrated with the NHAI One application to support more proactive road maintenance.
Urban rail and logistics
Urban transit in India is rapidly embracing open loop fare collection, allowing travellers to use interoperable cards and QR codes across multiple operators without switching payment systems, while train control technology is moving towards higher grades of automation that enable fully driverless operations with robust fallback modes and emergency overrides. Algorithms that analyse passenger flows are already adjusting headways, station dwell times and train frequency in real-time, and unified data feeds now let third-party apps plan, book and pay for multimodal journeys that may span the metro, bus, taxi or two-wheeler segments.
In this context, Alstom is supplying the latest generation of communications-based train control signalling system, together with seven years of comprehensive maintenance, for Indore and Bhopal. Alstom is also providing a train control and management system with automatic track inspection capability for high speed data transfer, full CCTV coverage with real-time links to the control centre, and intelligent video analytics that flag unattended objects and count passengers during evacuations.
On the logistics front, ULIP has logged 1 billion application programming interface (API) transactions as of March 2025, averaging 10 million calls each week and firmly establishing itself as a transformative force in Indian supply chains. By stitching together data across modes, ULIP eliminates information silos, enables real-time cargo tracking and streamlines regulatory compliance, benefits that extend from large conglomerates to MSMEs and start ups. Manufacturers such as Prism Johnson, Asian Paints and Tata Steel already rely on ULIP APIs to verify transport partners, automate workflows and fortify supply chain resilience, while multimodal endpoints covering road, rail, ocean and air provide live shipment estimated time of arrival (ETA) that support just-in-time inventory management and tangible cost savings.
Water
IoT allows interconnected sensors, meters and valves to exchange data instantaneously, creating a live information network that supports immediate decision-making. Similarly, smart meters measure water consumption in homes, industries and farms, warning users of overuse and curbing wastage, while water quality sensors track pollutants and detect changes in rivers, lakes and drinking water pipelines. Acoustic- and pressure- based leak detection systems pinpoint faults in pipelines before they escalate, and remote monitoring devices let officials check tank levels, pump status and flow rates from off-site locations. Also, automated irrigation systems linked to soil moisture sensors release water only when needed, significantly cutting usage.
India is applying these IoT and AI capabilities across numerous water management initiatives: under the Atal Mission for Rejuvenation and Urban Transformation mission, nationwide deployments of smart meters and sensors aim to improve supply and curb non-revenue water; Bengaluru’s Smart Water Grid integrates IoT, supervisory control and data acquisition systems and AI for real-time oversight of pressure and quality; Chennai’s HydroSense relies on AI-enabled sensors to track groundwater pollution; and IBM’s AI for Water programme in Delhi uses big data analytics to detect leaks and optimise distribution. Further, rural projects under the Jal Jeevan Mission employ remote IoT monitoring to ensure timely household water delivery. Furthermore, in Coimbatore, the municipal corporation is planning to roll out an IoT-based smart distribution system that groups houses into sub-district metering areas, using shared meters, valves and sensors connected via GSM to a central control panel for continuous oversight.
To combat Haryana’s growing water crisis, the Haryana Water Resources Authority has unveiled the Haryana Water Resource Atlas 2025, an AI-powered, geospatial platform aimed at monitoring, managing and conserving the state’s fast depleting water reserves.
