Environmental Sensitive Traffic Management (ESTM)
We reduce emissions, particularly in densely populated urban areas, by optimizing traffic management to our customers.
City traffic data + Real time data of engine and driving state + AQ data Microscopic, real-time emission modelling*
*for CO2, NO2, PM
Live data of emissions are extrapolated with live traffic volume data; the emission model is scalable from the entire city area to a single crossroad.
Improving air quality through traffic management at high emission locations by focusing on:
Minimize accelerations, continuous traffic flow, less stops and
enhancement of new mobility solutions (rerouting)
led to 20% improvement in NO2 emissions in city project

Immission Monitoring Box (IMB)
We monitor with a high precision measurement device to gain an accurate view of the air quality and to identify pollution sources.
Certified
according to EU air quality directive 2008/50/EC (39. BImSchV)
and BOSCH guaranty for data accuracy over life-time. 1)
Accurate
air quality monitoring with high time and spatial resolution.
Local measurement data
Immission Monitoring Box (IMB)
can be send to the cloud for analysis and further processing;
wireless data connectivity offers remote monitoring.
Robustness
