The NHAI will deploy advanced Network Survey Vehicles (NSVs) in 23 states, covering 20,933 kilometres of national highways. These vehicles are equipped with 3-D laser systems, 360° cameras, DGPS, IMU and DMI tools to collect detailed road-inventory and pavement-condition data including cracks, potholes and patches. Data will be uploaded to NHAI’s AI-based “Data Lake” portal, where experts will convert raw information into actionable insights. The data collection will occur before work on each 2-/4-/6-/8-lane project and subsequently every six months. The survey system supports better road-asset management, maintenance planning and riding experience for commuters.
By adopting high-resolution digital monitoring tools, India is modernising its infrastructure-management framework. This initiative aligns with the government’s push for smart highways, predictive-maintenance regimes and data-driven infrastructure policies. The improved asset-management capability helps reduce lifecycle costs, enhance safety and supports urban-rural connectivity, contributing to sustainable cities and resilient highways.
What is the NSV system? → The Network Survey Vehicle system is a specialised fleet equipped with sensor and data acquisition technology used to automatically measure, report and monitor the condition of highway infrastructure, enabling proactive maintenance and asset-management decisions.
What are DGPS, IMU and DMI?
DGPS (Differential Global Positioning System): Corrects GPS errors using ground reference stations, improving accuracy to under one metre.
IMU (Inertial Measurement Unit): Tracks motion and orientation through accelerometers and gyroscopes, ensuring accuracy even in low-signal zones.
DMI (Distance Measurement Instrument): Measures distance using wheel-rotation data, linking defects precisely to road-segments.
Relevant Question for Policy Stakeholders:
How will the collected NSV data be integrated with state-highway systems, budget allocations and road-safety programmes for maximum impact?
