How to respond to air quality pressure associated with electric vehicles ?
Qijie Zhang, Engineer for information system development around air quality numerical models, Aria Technologies
To date, a new environmental attention focuses on the relationship among traffic management, urbanization and pollution control. Several European cities want to improve the consideration of environmental pressures in urban planning and traffic management decisions to ensure harm reduction and thus make the city more attractive for residents and tourists. These decisions are, for example, introduction of electric vehicles (EVs) to develop a zero emission zone, urbanization and introduction of intelligent red light to control traffic flow and thus air pollution on important roundabout, etc.
The objective of this presentation is to assess the air quality in Roma and Hong Kong under direct influence of the traffic and to get a fine mapping of the pollution levels for scenarios :
Future configuration after introduction of EVs
We propose to explain this by high-resolution 3D modeling approach with MSS model. This type of study should serve as a basis for the development of EV introduction recommendations to reduce the pollution impacts and improve the comfort of the site (residential, business sensitive, tourist areas). In general, the study is mainly focused on primary pollutants, such as NO2 and PM in the proximity area. And it also shows the advantage of precise mapping and the knowledge of the vertical distribution of these pollutants.
In addition, the importance of the synergy between the "measures" and "modeling" experiences is particularly explicit in the methodology, especially in the design phase of the in situ campaign and the phase of the calibration / validation of 3D modeling.
