     The environment has an impact on every aspect of human life and every human activity affects the environment with social, technological and economic development. Abnormal consumption of various natural resources has increased the level of pollutants such as air pollution, chemical pollution, thermal pollution and radioactive pollution etc., which is increasing at an exponential rate, thus endangering our country’s rich ecology and environment. The major sources of air pollutants are man’s industrial manufacturing and motor vehicle operation activities, both of them have been concentrated in urban areas. Study area Coimbatore district is the second most populous city in Tamilnadu and spread over an area of 105.60 sq.km. Study area is well connected with other centres of the country by road, rail and air routes. The National highways are passes through the city. The study area for the present work deals with Carbon Monoxide from vehicular emission due to heavy traffic flow. Vehicular data were collected from 6 sample traffic junctions were selected and the vehicles running time, based on the peak hours of the traffic junctions. Geographic information systems (GIS) as management and supporting systems enable us to integrate and analyze air pollutants on environment. Finally spatial analysis such as overlay, buffering and IDW have been performed studied for carbon monoxide pollution in the city.
