This research aims to calculate PM2.5 concentration on the road network by considering the network-wide traffic status, which can be used to support research about the impact of urban road network pollution concentration on health.
The increase in the use and number of vehicles has brought about a large amount of vehicle exhaust emissions and increased urban air pollutants.
This is also one of the important reasons why this issue is worth studying.
In this research, traffic emission was an estimate based on network-wide traffic status which was calculated from vehicle trajectories and spatial variance-covariance matrix.
An identification method of external input pollutants is proposed to determine the occurrence of external pollutants imported into the urban area.
To calculate the impact of multiple influencing factors on the pollution concentration of the entire road network, a multivariate linear model was adopted to calculate a variety of influencing factors and calibrate the model parameters by collecting real data.
The results show that traffic emissions, external input pollution, and wind impact are the main factors affecting the PM2.5 concentration on urban road networks.
Combined with real-time traffic data, we can obtain the temporal and spatial characteristics of the pollutant concentration of the road network.
For policymakers, our research can provide a method for calculating the PM2.5 concentration on the road network, which is useful for establishing a health assessment framework in the future.
