COMPUTATIONAL MODEL FOR TRANSIENT POLLUTANTS DISPERSION IN CITY INTERSECTION AND COMPARISON WITH MEASUREMENTS

Popis výsledku v původním jazyce

Many city intersections are often heavily polluted due to intensive traffic. Dispersion of pollutants originating from traffic is directly connected with the geometry of the urban area and traffic conditions. The urban area is mostly heavily built-up area and buildings and other obstacles may significantly influence local concentrations. Moving vehicles enhance both micro- and large-scale mixing processes in their surrounding. Without taking account of traffic will lead to neglecting one of the most impportant phenomenon that influences mixing processes in the proximity of traffic paths. Influence of traffic is increasing namely in situation of very low wind speed. In this study authors focus on transient pollutants dispersion due to traffic dynamics in an actual intersection equipped with traffic lights located in the center of city of Brno. Inclusion of traffic dynamic leads to a better description of dispersion processes. Information about traffic situation were obtained from in-sit
