COMBINED APPLICATION OF TRAFFIC MICROSIMULATION AND STREET CANYON DISPERSION MODELS, AND EVALUATION OF THE MODELLING SYSTEM AGAINST MEASURED DATA
In this study, the traffic microsimulation model HUTSIM, used by Helsinki University of Technology, and a street canyon dispersion model OSPM were integrated. HUTSIM is designed specially for simulating signal controlled intersections and small areas consisting of several intersections. In 1997 a measuring campaign was conducted at a street canyon in Helsinki. The above mentioned location and time are considered in the study discussed in this paper, in order to be able to compare the simulation results with measured traffic flow and concentration values, as well as the corresponding previous computational results. The results of flow and emission computations obtained with the two modelling systems, involving traffic micro- and macrosimulation models, were first compared with each other. The predicted atmospheric pollutant concentrations were then compared with the measured data. The results were promising.
