According to Chandwar, in tunnels abroad such safety techniques require a separate software for every feature, making it difficult to be handled. Stating that the Chenani-Nashri tunnel can be called the "safest highway tunnel in the country", Chandwar said that the tunnel also has specialised cameras which would count the number of vehicles in the tunnel and accordingly set the speed limit. "The Traffic Control System in the tunnel has green and red lights, the speed limit signs and others are variable signs depending upon the traffic condition inside the tunnel," said Chandwar.
