NHAI to deploy 3D sensors to identify potholes, road cracks across 23 States, Pg12

Key Highlights:

• The NHAI will deploy advanced 3D sensors and data systems across 23 states to identify road defects over 20,000 km.
• This initiative aims to improve the riding experience and inform decisions on maintenance, asset management, and infrastructure planning.
• Data will be collected using 3D laser systems, GPS, and devices measuring acceleration and angular velocity.
• The collected data will be analyzed on the NHAI's AI-based Data Lake portal by a dedicated team of experts.

Detailed Insights:

• The NHAI aims to create a comprehensive inventory of road conditions to enhance the safety and efficiency of the national highway network.
• Data collection will occur before road development and then every six months, covering projects involving two- to eight-lane highways.
• The NHAI is also identifying "black spots" based on accident reports, having identified 13,795 such spots until March 2025.
• Long-term rectification has been completed on 5,036 black spots, with the e-DAR project serving as a central repository for road accident data.

Scientific/Technical Concepts Involved:

• 3D Laser System: A technology that uses laser beams to create detailed three-dimensional models of objects or surfaces.
• GPS (Global Positioning System): A satellite-based navigation system providing location and time information.
• Artificial Intelligence (AI): The simulation of human intelligence processes by computer systems.
