Tunnel Project ventilation system

Tunnels can help reduce air pollution by moving traffic off roads where people live and work putting it underground. In a tunnel, vehicle emissions can be controlled and dispersed more effectively and are monitored to ensure standards are met. With thousands of tunnels in the world, there are well-established and effective ways to design tunnels and ventilation systems so that there are no negative effects on local or regional air quality.Tunnel ventilation systems are designed to manage air quality both inside and outside the tunnel.
