Air Quality and Noise Monitoring for
Urban Mobility & Low Emission Zones
Bettair enables distributed urban monitoring of NO2, PM10, PM2.5 and many more configurable gases and noise according to project requirements. Nodes can be positioned at strategic locations to create continuous spatial and temporal information. Environmental variables help contextualize measurements, supporting analysis of mobility measures, localized episodes, public communication and evidence-based urban environmental management.
Environmental Monitoring Challenges in Low Emission Zones & Urban Mobility
Urban mobility policies require evidence showing how traffic and local conditions influence NO2, PM10 and PM2.5. Sparse monitoring may miss localized patterns, while noise adds another important environmental dimension. Without distributed, continuous information, municipalities may struggle to evaluate measures, investigate episodes, communicate results and prioritize interventions across complex urban areas.

Changing environmental conditions
Environmental conditions can vary by activity, location and meteorology, making isolated measurements difficult to interpret.
Complex operational environments
Low Emission Zones & Urban Mobility sites can contain multiple sources, receptors and operating conditions that require distributed visibility.
Need for continuous evidence
Time-linked data helps investigate episodes, compare locations and support environmental management with traceable evidence.
What to Monitor
Configure the monitoring network around the environmental objectives of the low emission zones & urban mobility project.
1
Particulate Matter
PM1, PM2.5 and PM10 measurements provide continuous visibility into particulate conditions across traffic corridors, urban areas and locations where population exposure is a relevant consideration.
2
Gases & Traffic Emissions
Configurable gas measurements can help characterize traffic-related air-quality conditions, with parameters selected according to the objectives and characteristics of the urban monitoring network.
3
Environmental Noise
Continuous acoustic monitoring can complement urban air-quality measurements by providing visibility into environmental noise around traffic corridors, mobility infrastructure and sensitive urban locations.
4
Environmental Conditions
Temperature, humidity, pressure and wind measurements provide context for interpreting changes in urban air quality and understanding how environmental conditions influence pollutant dispersion.
