Sažetak

Based on wind tunnel experiments and the yearly average calculating CAR model (Jonkers 2007) a new hourly average
calculating street canyon dispersion model is derived. With this hourly model, dispersion can be calculated for different types of
street configurations, varying in aspect ratio and building configuration. The model outcome is compared with measured
concentrations from the TRAPOS campaign. After applying linear regression, a correlation coefficient between the hourly measured
and the hourly modelled concentrations of 0.64 was found, the systematic error was 1.13.
