Description
Summary:Air pollution is more serious than before in Shijiazhuang in recent years, motor vehicle exhaust emissions is one of the major causes of air pollution. The economy is developing rapidly in Shijiazhuang, the motor vehicles increase at a rate of 20% per year. In August 2017, the number of motor vehicles exceeded 2.6 million in Shijiazhuang. In order to explore the relationship between the types of motor vehicles and air pollution in Shijiazhuang. This paper chose the traffic information of the typical roads which are Heping East Road and Yuhua East Road, and determined emission factors, such as CO, HC, NOx, PM10 and so on. The EDMS model was used to calculate the air pollutant discharge emissions inventory and compared with the traffic information. The conclusion is that small cars account for 85% of the total traffic volume, the vehicle exhaust account for 68% of CO, 74% of HC, 77% of NOx and 77% of PM10. Air pollution and the number of small cars have a great correlation. The pollutants contributed by motor vehicles mainly for the small car discharge, in order to reduce the air pollution, relevant departments can take effective measures which include road pricing and limit the number of motor vehicle.
