VEHICULAR EMISSIONS AND AIR QUALITY ASSESSMENT IN ROADWAY TUNNELS: THE SALIM SLAM TUNNEL

Motor vehicle emissions pose a serious environmental threat, particularly in confined spaces such as tunnels and underground parking garages. These emissions are characterized by the presence of various pollutants, which, at high concentrations, can cause adverse health effects. This paper presents an assessment of vehicle-induced emissions and air quality in a heavily-traveled tunnel located in metropolitan Beirut (Lebanon). For this purpose, common modeling theories were reviewed, relevant air quality standards were defined, existing conditions were determined, an air-sampling program was implemented, and mathematical modeling to simulate field measurements was conducted. Impact significance was evaluated by comparing measured and simulated pollutant concentrations with air quality standards. Model simulations are used to evaluate vehicle-induced pollutant emission factors. Mitigation measures are proposed to ensure proper air quality management in the tunnel.
