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.
