    In this paper wind tunnel dispersion tests and accompanying numerical simulations of the planned north section of the Budapest ring motorway M0 are reported. The investigated suburban area is located between hills and several tunnels and viaducts are planned. Wind tunnel tests were carried out on a 1:1000 scale model containing topography, buildings and vegetation in a Göttingen-type wind tunnel. Road segments were modeled as line sources, tunnel portals as point sources with horizontal momentum. Concentrations were measured in 50 sampling points. Numerical simulations of the same case were performed using the MISKAM code. Using both methods, large pollutant plumes near tunnel portals were observed, reaching also populated areas far from the motorway. In consequence, extension of the tunnel ventilation system by ventilation stacks was proposed. Effect of the stacks was proven numerically.
