AIR POLLUTION FROM MOTOR VEHICLES A MATHEMATICAL MODEL ANALYSIS: CASE STUDY IN IPOH CITY,PERAK, MALAYSIA.

Carbon Monoxide and Sulfur Dioxides concentrations and traffic volume data were collected at several locations in Ipoh City in the state of Perak in Malaysia. The sites were categorised into an enclosed area and an open area and at each site different vehicles driving mode were considered. A mathematical models based for pollutant concentration were developed using the least square method. Results from these studies indicate that the maximum concentration of pollutant is higher in an enclosed surrounding for all driving modes compared to an open surrounding similar traffic volume. The relationships derived between traffics flows and pollutants concentrations indicate that the adopted approach to forecast pollutant levels from traffic counts is workable for Malaysian situation.
