Technology deployment to identify road defects

Why in news?

In order to identify road defects, the National Highways Authority of India (NHAI) will deploy advanced sensors and data acquisition systems across 23 States.

• The NHAI will install cutting-edge sensors & data collection systems to detect road problems, such as potholes and cracks, throughout 23 states.
• Aim – To improve road quality, safety, and commuter experience by enabling data-driven maintenance and planning.
• NSV vehicles – Network Survey Vehicles (NSV) are fitted with advanced technology for high-resolution road surface mapping and creating a detailed profile of the road's condition.
• Equipped with – Advanced sensors and data acquisition systems, including a 3D laser-based system, a global positioning system (GPS), and an electronic device that measures an object’s acceleration and angular velocity.
• AI-based portal – The collected data is uploaded to NHAI's AI-based "Data Lake" portal, examined by the group of NHAI professionals.
• Road Asset Management System (RAMS) – The information collected at regular intervals is stored for future reference and technical purposes in RAMS for supporting long-term infrastructure planning and management.
• Data collection frequency – For all highway projects with 2, 4, 6, or 8 lanes, data will be collected will start before road development work starts, and thereafter, with a gap of 6 months.
• Use of collected data – It will help to make decisions on maintenance, asset management, infrastructure planning, and improving the safety and efficiency of the country’s National Highways network across the country.
