TNO is active in various projects in order to promote sustainable mobility and to make vehicles clean and economical. Within the CARES project, TNO advises policymakers on measurement methods to be used to enforce certain traffic emissions. In the uCARe project, traffic emissions and awareness of these are brought to the attention of the end user. TNO standardises emission data to give drivers personal advice and makes videos for awareness and behavioural changes, among other things.

CARES – City Air REMOTE emission sensing: Use of Measurements methods in Enforcement

For decades, cities and enforcement organisations have been trying to measure vehicle CO2 emissions in all kinds of ways. Until now, this was mostly done via fixed roadside set-ups or through the so-called 'snuffle bus’ which incorporates measuring equipment. The intention is for vehicles that cause high emissions due to poor maintenance or deliberate tampering to be removed from the road or be kept out of certain areas. However, the most commonly used measurement methods also have weaknesses. Fixed set-ups, for example, are less accurate due to the short measuring time, while the snuffle bus is relatively labour-intensive.

City Air Remote Emission Sensing (CARES) is a research project within the framework of the European Union’s Horizon 2020 programme. It brings together experts on traffic emissions from across Europe to work on more accurate and reliable ways of measuring these. The objective is to lower the threshold for using measurement methods in enforcement.

After all, only through enforcement on a large scale we will be able to reduce road traffic emissions worldwide. This will be achieved through a combination of technology development, new analysis techniques, demonstrations and the widespread dissemination of research results. The project started in 2019 and will last at least three years. TNO is one of the 18 partners involved.

Within the CARES project, TNO is working on higher precision and the complementary applicability of all types of systems. By installing cameras above the road and connecting them to a weather sensor and an emission meter, for instance, measurements can be made remotely and over long periods of time. This ensures more accurate measurements, enabling policymakers to make faster and more effective decisions in order to ultimately achieve zero emissions.

uCARe – You Can Always Reduce Emissions, because you care

Air pollution is one of the greatest societal challenges globally. New technological innovations and stricter legislation have led to significant reductions. Nevertheless, road traffic emissions are still too high. Since 2019, TNO has therefore been working with 13 partners in the uCARe research project, which is part of the European Union's H2020 programme. This project is unique in that it aims to reduce traffic emissions by involving road users and actively informing them of the contribution they can make to clean driving.

In collaboration with cities, regions and NGOs, uCARe organises events in which citizens can use measurements to determine how much their car is emitting, for instance. Diesel cars in particular play a major role. And by installing a special sensor in the car for some time, these emissions can also be measured over a longer period. Other teaching aids and tests that can be carried out at home help to give road users more insight into the air pollution caused by vehicles. Within the project, TNO is standardising emission data at a detailed level in order to be able to offer drivers personal advice. In addition, TNO is creating videos and other educational materials for use at events and pilots for the campaigns of municipalities and NGOs.
