"proved the capacity of the rsd to collect empirical, real driving and accurate traffic emissions data remotely and non-intrusively"

case of study

Working hand to hand both with Spanish Government, DGT and CIEMAT, the ultimate goal of this project is to propose emission limits for discriminating the minimum group of the most polluting vehicles and draw conclusions for the development of appropriate legislation aimed at reducing emissions from motor vehicles.

scope of works

The aim of this project is to provide technical support for the creation of a legal framework in order to face the problem of the air pollution from motor vehicles.


As a starting point, it becomes necessary to characterize empirically and accuratley the emissions of the different on road traffic pollutants into the atmosphere. The conclusions will help guide, improve and develop specific policies with a significant impact in reducing these emissions type, hepling to improve air quality.


The project was executed in 4 months around the city of Madrid, covering a total of 28 different locations and getting more than 195.000 vehicles collected.

Vehicle characterization of the city of Madrid in the measured locations per fuel type, vehicle category and purchasing power is as follows:

main conclusions of the study

1.  RSD average uncertainty less than 8%

 

2.  The gap between what is demanded by the Euro Standards and what actually is emitted is increasing with time. Newer vehicles do not imply lower emissions. Particularly significant is the case of the NO for diesel passenger cars.

 

3.  Identifying only the 6,4% of the most emitting vehicles (HE), a reduction in CO, HC and NO of 39,5%, 38,3% and 19,1% respectively can be achieved.

 

4.  Within the HE group (6,4%), the 25,6% correspond to Euro 5 diesel passenger cars

 

5.  Repairing the most emitting vehicles (6,4%) would be at National level:

 

  • Emissions reduction to the environment of 266.685t, 16.943t and 229.807t in CO, HC and NO respectively

 

  • Emissions savings of 14,8% for CO, 2,8% for HC and 22,7% for NO compared to the “Inventory of Air Emissions in Spain” (MAGRAMA, 2012)”

 

  • The emissions reduction estimates cost savings exceeding 1.700 M€
