Abstract

In this study, the traffic micro-simulation model HUTSIM, used by Helsinki University of Technology, and a street canyon dispersion model OSPM (Operational Street Pollution Model) were integrated. HUTSIM is designed especially for simulating signal-controlled intersections and small areas consisting of several intersections. In 1997 a measuring campaign was conducted in a street canyon (Runeberg's St.) in Helsinki. Hourly concentrations of CO, NOx, NO2 and Og were measured at street and roof levels. The relevant hourly meteorological parameters were measured at roof level; these included wind speed and direction, temperature and sola
