A computer model consisting of wind distribution, emissiondispersion, modified Gaussian equa- tion, and stochastic predictionmodels has been developed to identify street canyon and vehicle wakeeffects on the transport air pollution from urban roadmicroenvironments. In this work, wind flow and their com- ponents inthe street canyon are simulated and analyzed considering atwo-dimensional street canyon flow pattern. Wind parameters obtainedfrom the analysis are then applied to estimate wind speed and vehiclewake turbulence in microenvironments.
