Effectiveness in Evaluating Roadside Air Quality for Milan Government

Sector：Traffic and Marine Emission

Location：Milan, Italy

The traffic emissions are generally monitored by the traditional fixed reference stations. However, those stations are not only expensive to operate, but also unable to monitor emission sources at a close range. This limited their effectiveness in studying local pollution problems. To better understand the traffic emissions in Milan, Italy, the city's environmental agency AMAT (Agenzia Mobilità Ambiente e Territorio) deployed three Sapiens MAS-AF300 in the city to evaluate the advanced air quality sensors compact station’s capability to detect exposure to vehicular traffic-related emission

High Density Sensor Network Inside Bus Terminus to Monitor Air Quality for Hotspot Identification

Sector：Tunnel, Parking and Transportation Hubs

Location：Kwai Chong, Bayview Garden, Shatin, Lam Tin, Hong Kong

The air quality inside the semi-enclosed bus terminus has been a great challenge in urban settings. Sapiens air sensors (NAS-AF300) is used in Hong Kong by government agencies to closely monitor the air pollutants of NO, NO2, CO, CO2 and PM2.5 from traffic emission inside the bus terminus. The high-density network creates a real time air pollution map to identify the hotspot of air pollution and diagnose the critical causes of the air pollution issues. It also helps to evaluate the effectiveness of the mitigation measures.
