calculation of exhaust emission - Opis:
- Traffic is a major source of pollutant emission in cities. In order to evaluate the air quality in urban areas it is necessary to use appropriate traffic flow and exhaust emission models. In air quality studies, the common approach of constant average emission intensity is used for describing emission along a whole road i.e. one road - one linear source. This approach can not be used in case of analysing local air pollution caused by traffic on roads between intersections and on roads with input or outputs. In the paper a method of dividing road on several segments is presented. Each segment represents linear source of emission. The method enables modelling of exhaust pollutant emission intensity taking into account its local changes. The average speed of traffic flow and density of vehicles is obtained from microscopic traffic flow model. Next, average exhaust pollutant emission intensity is calculated using the average emission factor method (European models COPERT or INFRAS can be applied). Some calculation results are presented in the paper as well. The algorithm of dividing road on segments using microscopic traffic flow model presented in the paper is a solution which enables more precisely identification of regions in which the exhaust emission is high and the permissible concentration of vehicle exhaust pollutant can be exceed.
