Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0025] Such as figure 1 As shown, a kind of evaluation road traffic characteristic that the embodiment of the present invention discloses is to inhalable particulate matter (PM 10 ) method for the influence of emission concentration, comprising the following steps:
[0026] Step 1) Obtain the traffic analysis zone (TAZ) information in the research area: select the most commonly used traffic analysis unit—traffic analysis zone (TAZ) as the research object, obtain the vector map file (shapefile) corresponding to the traffic analysis zone, use ArcGIS software can obtain the basic attributes of each traffic analysis area, such as visualizing the specific location of each traffic analysis area in the entire research area, calculating the area of the traffic analysis area, etc.;
[0027] Step 2) Obtain variables such as population economy, emplo...
