Suzhou Road Vehicle Emissions Co Pollution Characteristic Research

It is an indisputable fact that people pay more and more attention on effect of Automotive Emission of SuZhou city. on this background, this paper research on CO,According to meteorological factors and the characteristics of urban street,research on the facter of pollutants, diffusion and transport of pollutants. To provide experimental model for prediction and control of Traffic pollution and air quality. The results are as follows:(1) From the road type, CO pollution is relatively light Yangcheng Lake Avenue, the second is the modern Avenue and Star Harbour Street, Intersection of the most serious. Diurnal variation of CO concentration and traffic flow is similar to the peak of its basic agreement with the rush hour, there was a significant linear relationship between the two.(2) Other factors such as street layout, the layout of the building also have an impact on the spread of pollution, but relatively smaller. Rational arrangement of streets and buildings will minimize pollution. CO concentration and wind speed, temperature, a negative correlation.(3) Simulation model selected CALINE4 The modern Suzhou Star Avenue and Port Street, The modern road at the intersection of CO concentration in the air. By CALINE4 model analysis of principles and parameters, select the parameters of CO-sensitive and the collection, simulation results compared with field monitoring results show a good correlation between the two, indicating that the selected model to simulate similar CALINE4 Suzhou City in the open-type The modern road star road and intersection of Port Street junction CO concentration of these is applicable.
