Research progress on vehicle exhaust emission factor model and dispersion model

摘要: Population, economy, resources and environment have received considerable concerns for human beings. A lot of are consumed due to demographics growth prospects, while excessive utilization result in pollution problems which intensified the conflict among population, economy on account development industrial production transportation. large amount fossil fuel by vehicles that exhaust gas emission more than 100 kinds pollutants such as CO2, CO, NO2, SO2, PM2.5 so forth, these aggravate greenhouse effect air pollution. The paper reviewed vehicle factor diffusion model at home abroad, summarized existing research, then scientific outlook were carried on. Proposals proposed research should take mountainous area highway might stay away from interference residential areas. review not only can help scholars build high accuracy dispersion model, but also provide control foundation decision-making.
