The National Highways Authority of India (NHAI) announced on October 22–23, 2025 the deployment of Network Survey Vehicles (NSVs) equipped with 3D laser sensors, 360-degree high-resolution cameras, DGPS, IMU, and DMI across 23 states, covering 20,933 km of national highways. The NSVs automatically detect road defects — cracks, potholes, and patches — without human intervention. All collected data is uploaded to NHAI's AI-based 'Data Lake' portal for expert analysis. Surveys will be conducted before project commencement and at six-month intervals thereafter. The initiative aligns with India's push for data-driven, technology-enabled infrastructure management.

Frequently asked questions
What are Network Survey Vehicles (NSVs) deployed by NHAI and what technology do they use?
Network Survey Vehicles (NSVs) are advanced road inspection vehicles deployed by NHAI across 23 states covering 20,933 km of national highways. They are equipped with 3D laser sensors, 360-degree high-resolution cameras, DGPS (Differential Global Positioning System), IMU (Inertial Measurement Unit), and DMI (Distance Measuring Instrument) to automatically detect road defects.
What is NHAI's 'Data Lake' portal and how does it function?
NHAI's 'Data Lake' is an AI-based portal where all data collected by the Network Survey Vehicles is uploaded for expert analysis. It enables data-driven decision-making for highway maintenance and infrastructure management without human intervention at the data collection stage.
How frequently do NHAI's Network Survey Vehicles conduct road surveys?
NHAI's Network Survey Vehicles conduct surveys before project commencement and thereafter at six-month intervals. This regular monitoring ensures timely detection and repair of road defects such as cracks, potholes, and patches.
How many states and kilometres of national highways does NHAI's NSV deployment cover?
NHAI's Network Survey Vehicle deployment covers 23 states across India, monitoring 20,933 kilometres of national highways. This large-scale deployment represents India's push for technology-enabled infrastructure management.
What types of road defects can NHAI's Network Survey Vehicles automatically detect?
NHAI's NSVs can automatically detect road defects including cracks, potholes, and patches without any human intervention. The collected data is then analysed by experts through NHAI's AI-based Data Lake portal to plan maintenance activities.
