New Delhi: The National Highways Authority of India (NHAI) has announced plans to introduce advanced sensor-based technology to detect potholes, surface cracks and other structural defects along more than 20,000 km of highways across 23 States.
According to an official statement, vehicles equipped with modern sensors and data acquisition systems, including 3D laser scanners, GPS trackers and instruments that measure acceleration and angular velocity, will be deployed to capture detailed data on road surface conditions.
The collected information will be uploaded to NHAI’s AI-based ‘Data Lake’ portal for analysis, helping experts generate actionable insights for road maintenance, asset management, and long-term infrastructure planning. The analysed data will also be stored in the Road Asset Management System for future technical reference.
NHAI stated that data collection will take place before the commencement of new highway projects and every six months thereafter. The project will cover all categories of highways, ranging from two to eight lanes, and bids have already been invited for implementation.
Reports also stated that NHAI is continuing its efforts to identify and rectify accident-prone “black spots” across the country.
It was also stated that 13,795 such locations have been identified up to March 2025 and corrective measures have been completed at 5,036 sites so far. Additionally, the Authority has developed the Electronic Detailed Accident Report (e-DAR) platform, a centralised database for recording and managing accident data, to strengthen road safety measures and reduce fatalities nationwide.
