Advanced Monitoring of Road Conditions
NHAI Launches AI-Driven Network Survey for 20,000 km Highways: The National Highways Authority of India (NHAI) has initiated the large-scale deployment of Network Survey Vehicles (NSVs) across 23 states, covering a stretch of 20,933 kilometres. The aim is to enable smoother, safer, and more efficient travel on India’s extensive National Highway network. The vehicles will collect detailed data on road conditions and structural quality, ensuring timely maintenance and enhanced public safety.
These NSVs are designed to detect potholes, cracks, and uneven surfaces, allowing for accurate and data-backed maintenance decisions. By replacing manual inspection with technology-based monitoring, the initiative represents a major leap towards a scientific approach in road infrastructure management.
Static GK fact: The NHAI was established in 1988 under the National Highways Authority of India Act, and it functions under the Ministry of Road Transport and Highways (MoRTH).
Integration with Artificial Intelligence
A core component of this initiative is the integration of NSV data into NHAI’s AI-enabled ‘Data Lake’ platform. This digital repository allows experts to process real-time data and generate actionable insights. The data will guide policy decisions, prioritise maintenance, and improve transparency in road management systems.
The AI-based Data Lake supports predictive analytics, enabling authorities to plan maintenance activities before major deterioration occurs. This approach will help optimise budgets and reduce the overall cost of long-term infrastructure maintenance.
Static GK Tip: The use of Artificial Intelligence in infrastructure governance was officially recognised under the Digital India initiative to promote evidence-based planning and transparency.
3D Laser and Precision Mapping Technology
Each NSV is fitted with 3D laser technology, 360-degree high-resolution cameras, Differential Global Positioning Systems (DGPS), Inertial Measurement Units (IMU), and Distance Measuring Indicators (DMI). These tools collectively provide high-precision measurements, ensuring accurate mapping for 2, 4, 6, and 8-lane highway projects.
The surveys will be conducted every six months, aligning with government mandates for continuous infrastructure assessment. The data will assist in identifying weak sections and planning preventive maintenance well before visible damage occurs.
Static GK fact: DGPS offers accuracy within 10 centimetres, making it vital for engineering, mapping, and highway construction projects.
Toward Future-Ready Road Asset Management
The systematic use of NSVs marks a major transformation in India’s approach to road asset management. By combining AI analytics with real-time field data, NHAI is ensuring a transparent, accountable, and efficient mechanism for monitoring highway health.
This initiative will enhance road safety, optimise maintenance budgets, and support the creation of future-ready highway infrastructure. It reflects India’s commitment to adopting advanced technologies for sustainable development and efficient governance.
Static GK Tip: India’s National Highways network spans over 1.45 lakh kilometres and carries about 40% of total road traffic, despite forming only 2% of the total road length.
