MUTHUSUBRAMANIANAbstract An independent traffic survey is conducted at thirty selected points by physical counting in both directions of the traffic flow to estimate the emission rates of the traffic related gaseous pollutants such as carbon monoxide, nitrogen oxides and sulphur dioxide within the urban limits, as automobiles are the key sources of air pollution in Madurai city.
