The invention relates to a method for determining a response relationship between pollutant concentration and traffic flow, and belongs to the technical field of ambient air monitoring. According to the invention, the background concentration of the target point is determined by using the concentration data of the air quality monitoring station, and the background concentration is deducted from the concentration data collected by the traffic monitoring station at the target point to obtain the traffic environment pollutant concentration at the target point; the time period in which the traffic flow changes obviously is found to serve as the event time period, the traffic environment pollutant concentration change rate and the traffic flow change rate in the reference time period and the event time period are calculated, the difference caused by environmental conditions in different seasons is reduced through the relative change rate, the subsequent fitting precision is improved, and the fitting precision is improved. Therefore, the accuracy of the determined response relationship between the pollutant concentration and the traffic flow is ensured, and a reliable basis is provided for subsequent research on the relationship between the pollutant concentration and the traffic flow.

    本发明涉及一种确定污染物浓度与交通流量响应关系的方法,属于环境空气监测技术领域。本发明利用空气质量监测站的浓度数据确定目标点的背景浓度,从目标点处的交通监测站采集到的浓度数据中扣除背景浓度,以得到目标点处的交通环境污染物浓度;通过寻找车流量明显变化的时间段作为事件时间段,计算在基准时间段和事件时间段的交通环境污染物浓度变化率和交通流量变化率,使用相对变化率来减少不同季节的环境条件所带来的差异性,提高了后续拟合的精度,进而保证了所确定的污染物浓度与交通流量响应关系的准确性,为后续研究污染物浓度与交通流量的关系提供了可靠的依据。
