Context
The Ministry of Road Transport and Highways (MoRTH) has deployed Network Survey Vehicles (NSVs) across the country to strengthen the monitoring and assessment of National Highway infrastructure through advanced technology and data-driven surveys.”
About Network Survey Vehicle (NSV)
- It is equipped with advanced technologies such as 3D laser systems, GPS, high-resolution cameras, video imaging tools, Inertial Measurement Units (IMU), and Distance Measuring Indicators (DMI).
- The system can survey up to 300 km of highway network per day.
- NSVs collect data on road inventory, pavement condition, and other highway assets.
- They identify defects such as cracks, potholes, rutting, ravelling, roughness, edge breaks, and damaged lane markings.
- The surveys also capture information on carriageway type, shoulder width, median details, topography, land use, utilities, and right of way.
- Surveys are conducted for 2-, 4-, 6-, and 8-lane highway projects before the start of work and subsequently at six-month intervals.
- The collected data is uploaded to NHAI’s AI-enabled Data Lake platform for analysis and decision-making.
- Survey data is encrypted, transmitted to a central processing centre, and reviewed by expert teams.
- The technology has reduced the time required to generate actionable reports from 4–6 months to about 10 days.
