A simple dynamic model for the dispersion of motorway traffic emission

In this work a modeling approach is introduced for the dispersion of motorway traffic emissions. The process model is developed for a distributed parameter system, and is derived based on the conservation law within the balance volumes between the road and the rural area, specified by the wind direction. Parallel to the wind, plug flow is considered, and for the absorption of pollution a simplified version of the Gaussian plume model is used. For the boundary conditions of the model, the output of the macroscopic emission model, introduced in [Csikós et al. (2012)] is substituted. A sensitivity analysis is performed on the proposed model which justifies the preconception on the future control system structure.
