The National Highways Authority of India (NHAI) deployed Network Survey Vehicles (NSVs) equipped with advanced 3D laser-based systems across 23 states, covering 20,933 km of national highways. The vehicles use high-resolution 360-degree cameras, DGPS (Differential Global Positioning System), IMU (Inertial Measurement Unit), and DMI (Distance Measuring Indicator) to automatically detect road defects including cracks, potholes, and patches without human intervention. The collected data is uploaded to NHAI's AI-based 'Data Lake' portal for analysis. Pavement condition surveys will be conducted before work begins on each project and at six-month intervals thereafter. The initiative aims to improve road safety, reduce accidents, and optimise maintenance costs.
