The simulation of CO diffusion of traffic emission in signalized intersections of Changchun

For researching the diffusion regular pattern of traffic exhaust pollution in urban signalized intersections. In this paper, according to the measured environment meteorological parameter, the features of traffic flow and the monitoring data of CO mass concentration, the traffic exhaust pollution in the typical signalized intersections of Changchun was researched. The result shows that combining the box model with the correction form of Nichoson box model to simulate urban traffic exhaust pollution in the signalized intersections, the result could be in good agreement with the measured value. Reference value can be provided for scientific decision-making pollution controlling on intersections.
