NETWORK SURVEY VEHICLES (NSVS)

NEWS

  • The National Highways Authority of India (NHAI) announced the deployment of Network Survey Vehicles (NSVs) across 23 states, covering 20,933 km of National Highways.
  • Objective: To collect, process, and analyse road condition data for better maintenance and safety.

HIGHLIGHTS

What are Network Survey Vehicles (NSVs)?

  • Specialised vehicles equipped with:
    • Laser scanners
    • GPS and IMU sensors
    • High-resolution 360° cameras
    • Distance Measuring Indicators (DMI)
  • Function: Conduct automated road and pavement condition surveys detecting:
    • Cracks, potholes, ravelling, rutting, edge breaks, and faded lane markings.

Need for NSV Deployment

  • India faces chronic issues of poor road maintenance, leading to:
    • Higher accident rates
    • Reduced vehicle efficiency
    • Premature infrastructure deterioration
  • Despite policy guidelines (2019) for NSV-based road surveys, implementation has been limited.

Road Asset Management System (RAMS)

  • Developed by Ministry of Road Transport and Highways (MoRTH).
  • Serves as a digital “Datalake” for:
    • Planning, budgeting, and lifecycle management of NHs.
    • Storing and analysing NSV survey data for scientific maintenance decisions.

 Implementation Details

  • NHAI to survey 20,933 km (91,280 lane km) of NHs.
  • Divided into 5 zones:
    • North (2,687 km) | West (3,915 km) | Centre (4,616 km) | South (4,537 km) | East (5,179 km)
  • Data collection every six months using 3D laser-based systems.

 Significance

  • Enhances transparency & accountability in highway maintenance.
  • Enables data-driven decision-making for asset management.
  • Reduces human intervention and ensures real-time defect detection.

 About NHAI

  • Autonomous agency under MoRTH.
  • Responsible for development, management, and tolling of NHs (~50,000 km).
  • Ensures highways remain safe, pothole-free, and efficient.
