Overview of Research on Vehicle Exhaust Based on OSPM Mode

Diffusion simulation of vehicle-related pollutants in street canyons has been widely carried out.OSPM diffusion model has been widely used because of its empirical data base.In this paper,OSPM development history,application research and challenges are reviewed.The results show that OSPM is closer to the real value than the simulation results of other models.In addition,studies on motor vehicle related pollutants in the past three decades have shown that OSPM model is more practical in pollutant prediction and exposure assessment.However,traffic-related factors will affect the prediction results of OSPM model,so new and more applicable algorithms need to be developed in the future to eliminate restrictive assumptions and improve the application scope of the model.
