Key Features of Network Survey Vehicle

• It is equipped with laser profilers, GPS and cutting-edge imaging technology.
• It is equipped with advanced 3D laser-based systems across all states and its network.
• With advanced technology, NSV surveys up to 300 km daily.
• It is usually a specialised van or SUV equipped with multiple sensors and instruments.
• It consists of Laser, Global Positioning System (GPS), Video image processing tools, High-resolution cameras, Inertial Measurement Units (IMU), and DMI (Distance Measuring Indicator).

Working of Network Survey Vehicle

• The survey will capture 13 types of defects, including crack measurement, ravelling, patch area, potholes, edge break, roughness, rutting, lane marking, etc.
• It will also cover details like carriageway type, road type, pavement and shoulder width, topography, median details, right of way, utilities, land use, etc.
• The data will be collected for all projects involving 2/4/6 and 8 lanes with NSV before the start of work and thereafter at regular intervals of six months.
• Data collected through NSV survey will be uploaded on NHAI’s ‘AI’ based portal Data Lake, where it will be analysed to transform data into knowledge and subsequent actionable insights.
• Raw survey data is encrypted and transmitted to the centralised NSV centre within 48 hours.
• Expert teams, strategically deployed across five zones, monitor and report findings systematically.
• Within 10 days, raw data is transformed into actionable insights — a process that earlier stretched to 4-6 months.
