A mathematical model of wind flow, vehicle wake, and pollutant concentration in urban road microenvironments. part I: model description

Artificial Neural Networks in Vehicular Pollution Modelling

“…Kunler et al [143] have discussed the applicability of various air quality models in describing the dispersion of car exhaust emissions and its effect on forest cover. Karim and Matsui [169] and Karim et al [170] have developed a computer model consisting of wind distributions, emission dispersion and modified Gaussian equation to identify street canyon and vehicle wake effects on transport of air pollution from the urban road microenvironments. solution of the Navier-stokes equations, two dimensional semi-empirical models, zero-dimensional semi-empirical models and empirical adaptation of Gaussian line source dispersion to model air flow and mass dispersion in street canyons.…”

Determination of trace metals in air of Chittagong city-Bangladesh

“…Particulate matter has a direct effect on health as a result of respiration, because of the small size of the particles and the effect of heavy metals on biochemical mechanisms. Fine particles are more easily transported large distances and can stay in the air for a long time, depending on meteorological conditions and the size distribution [8]. It has been estimated that exposure to fine particulate matter in outdoor air leads to about 100000 deaths (and 725000 years of life lost) annually in Europe [9].…”

Semi-Empirical Model of the Simulation of Traffic Pollution Dispersion near Roadways

“…As the type of traffic pollution source is not the point one, it is attempted to solve this problem by finding the pollution source, e.g. by replacing the road with a line of points imitating emission (Chock 1978) or with a system of planes, formed of such points (Karim, Matsui 1998;Rao et al 2002). In all cases the results obtained were only satisfactory, although complex computer programme packages were used.…”
