Funding: Horizon 2020 (EU)
Duration: 2019-2023

The project brings together Europe’s experts in non-intrusive vehicle emission measurement to investigate the use of different remote sensing techniques for monitoring real-world vehicle emission performance and enforcing compliance with exhaust pollutant standards. CARES's goal is to optimize the functionality of remote emission detection tools by making the data management and analytical capabilities of these systems more efficient with a view to a large-scale use for vehicle emission monitoring and the enforcement of related regulations. To this end, CARES will integrate existing commercial remote emission detection tools with two other non-intrusive, contactless methods developed to maximize system efficiency in practice. Innovhub SSI has recommended the city of Milan for the performance of one of the three scheduled remote emission sensing campaigns with the installation of vertical remote detection technology and will take care of local experimental and testing activities.

The Milan remote emission sensing campaign 2021

In order to achieve the goal of the CARES project to determine the 'real' emission factors of vehicles circulating on the road using remote monitoring (remote sensing), the Italian project partners AMAT e Innovhub SSI support the participation of Milan, which, together with Krakow and Prague, is one of the pilot cities of the project in order to evaluate the potential of remote vehicle emission monitoring techniques.

The Milan Campaign took place from September 23 to October 18 2021 and involved three road sections.

For the measurements advanced scientific research instruments of the highest level were used, positioned on ordinary parking areas already existing on the carriageway, on the side of the road, and made available by German, Austrian, US, UK and Italian companies and research institutes. At the same time, air quality measurements were carried out to complete the definition of the local environmental framework.

Innovhub and the Ministry of Transport guarantee the absolute protection of privacy and the non-traceability of vehicles.

The results of the studies emerged thanks to monitoring with remote sensing will allow to develop an accurate dataset of vehicle emission factors for the improvement of local emission inventories and, in the future, to evaluate the opportunity to subject the most polluting vehicle models to specific laboratory or road tests.
