Acoustic noise and air pollution are among the most prominent environmental stressors in cities. Both stressors often occur simultaneously because their main source is urban traffic. Associations between noise and air pollution at the relevant geographical unit of analysis need to be carefully considered in particular in complex urban areas. Low correlations near roads, however, suggest that independent effects of road noise and traffic-related air pollution can be reliably determined. We will first provide a kriging model based on road network distance metrics to do spatial interpolation on traffic data to obtain integral real-time traffic information. With this database, the road traffic noise mapping and traffic-related air pollution estimation could be well generated. The pollutants emission quantity forecast is calculated according to link traffic volume, intersection traffic volume,road network traffic flow,vehicle type and road grade.Finally, we will generate an evaluation index based on pollution emission quantity and diffusivity concentration. From this research, a comprehensive evaluation on the impact of traffic conditions on urban environment and its numerous influencing factors are realized and discussed, making it feasible to quantitatively explore the spatial distribution of traffic noise and traffic-related air pollution. This kind of study can also be applied in Environmental Impact Assessment and Urban Planning.
