| Abstract: | Based on investigation of vehicle flow、NOx concentration and themeteorological features of Luoshi Road, to analyze the characteristics of traffic flow, decide the formula of exhaust emission, and focuse on the relationship between the NOx concentration in the street environment and the different factors, it is found that the law of NOx dispersion in the low street canyon is different from the former result, at last, the parameters of the dispersion model is revised. The paper provides foundation for the low street canyon NOx dispersion model. |
