Abstract Information :
Maintaining good air quality in road tunnels is crucial for ensuring the safety and health of both drivers and maintenance workers. Road tunnels are a confined space that can accumulate high levels of pollutants from vehicle emissions, such as carbon monoxide, nitrogen dioxide, and particulate matter. The strategy adopted to improve air quality in road tunnels is to dilute the pollutants by providing a large intake of fresh air injected by a ventilation system. Tunnel operators need to ensure that the ventilation system is correctly adjusted to provide safe levels of air pollution but also to minimise energy consumption. This requires the use of accurate air pollution monitors that can reliably measure the air quality in real time.
Access to any equipment installed in a road tunnel is very restricted. As such air pollution monitors for use in a road tunnel must be very reliable, with calibration and maintenance intervals of at least 6 months. These challenges have resulted in the use of air pollution monitors that are specifically designed and tested for use in road tunnels.
