NHAI: Network survey vehicle mandatory for road condition survey

14 Apr 2021 Editorial Team

National Highways Authority of India (NHAI) has decided to deploy Network Survey Vehicle (NSV), aiming to enhance the quality of the national highways.

The deployment aims to help in enhancing the overall quality of the highways as NSV uses the survey techniques such as digital camera for 3600 imagery, record images and videos at regular intervals, laser road profilometer and other related technology for measurement of distresses in road surface. NSV shall also help to collate data to analyse the road condition including measurement of the road surface, surface cracking, potholes and patches and shall also provide data insights relating to side drains, road furniture etc.

Carrying out road condition surveys using NSV on the national highways has been made mandatory at the time of certifying completion of the project and every six months thereafter. The provision has also been included as a part of the standard bidding document of consultancy services.

The data collected through NSV survey shall be uploaded on NHAI’s AI based portal data lake, where it shall be analysed by Road Asset Management Cell (RAMS Cell) to assess the condition and roughness of the road to prioritise for the maintenance. The data will help in maintaining up to date asset inventory and road assets condition status. Apart from delivering vital information on road network planning, providing relevant information on other aspects such as development of road safety measures, etc. it will also assist in developing highway maintenance strategies, analysis of maintenance and selection of optimal maintenance regime.

The data collected through NSV surveys will highlight deficiencies in road conditions, prompting BOT operators and NHAI officials to take corrective steps to bring the road condition to the desired level. This will further result in better upkeep of national highways, leading to more comfort and better travel experience for highways users.
