ROAD TRAFFIC IMPACT ON AIR QUALITY NEAR MAJOR INTERSECTIONS IN BANGALORE CITY - INDIA

An attempt has been made to assess the air pollution concentrations from road traffic. Traffic flows and air pollution concentrations of CO, NOx, SO2 and SPM were measured concurrently with vehicle speed and wind speed, during morning peak traffic hours from 8:00 am to 12:00 pm during from June to December 2001. Traffic flows were measured continuously during the morning peak traffic hours by video-technique at twelve major intersections and air pollutant levels were measured at the height of 3m from the road surface and analyzed in the Ambient Air Quality Monitoring Mobile Laboratory. From the statistical analysis, it is evident that the air pollutant concentration levels are closely related to the traffic flow and average vehicle speed and the relationships between the air pollutant concentrations and the traffic flow and average vehicle speed. It is evident that the traffic-generated air pollution in the study intersections were high and it may be attributed to the interrupted flow of traffic near the intersections due to frequent 'stop' and 'go' situations.
