Air Quality Assessment For Road Tunnel

About the project

Every tunnel is different, and its effect on health has to be judged accordingly. Health-based exposure limits are used to set limits for in-tunnel pollution. The impact depend on factors that determine vehicle emissions (traffic volume, speed, fleet composition, road gradient, fuel quality and tunnel length) and the rate of dilution (governed by the tunnel’s ventilation system, and by traffic volume and speed). In most tunnels, there is a feedback system so that high concentrations of pollutants trigger either an increase in ventilation or traffic management measures aimed at reducing total vehicle emissions inside the tunnel.
