This paper presents an air quality impact assessment at a typical intersection in Beirut where a grade separation is proposed. Computer simulations were conducted to define concentration in the air of selected pollutants. Simulations were performed for worst case scenarios including with and without grade separations and changes in vehicle mix. The assessment of the impact significance of air emissions was then conducted by comparing the predicted pollutants concentrations with baseline air quality levels and relevant air quality standards with the objective of optimizing the intersection management in terms of minimal air quality impacts.
