Pollution radar

Airea uses pollution radar to measure vehicle emissions in real traffic conditions. 
 
This remote sensing device measures vehicle exhaust particles as well as a range of gaseous pollutants : 

​

  • Hydrocarbons (HC)

  • Carbon monoxide (CO)

  • Carbon dioxide (CO₂)

  • Nitrogen monoxide (NO)

  • Nitrogen dioxide (NO₂)

  • Ammonia (NH₃)

 

Measurements are carried out in real time and non-intrusively. 

​

They can be of major interest to a local authority when setting up a Low Emission Zone (LEZ) on its territory. Pollution radar makes it possible to : 

​

  •  A vehicle control point

  • Improved knowledge of the local vehicle fleet

  • Improved scientific knowledge of actual vehicle emissions

  • Communication on the subject to raise individual awareness of our mobility choices, our driving habits and their associated emissions

The pollution radar also makes it possible to identify the most polluting vehicles and to optimize the detection of heavy goods vehicles that defraud anti-pollution systems.  

 

Anti-pollution devices called "SCR" are now fitted to many heavy goods vehicles. An additive called AdBlue is injected into the exhaust system upstream of the SCR system and reduces the concentrations of nitrogen oxides (NOx) in the exhaust gases. If the AdBlue tank is empty, the truck's engine "restricts" itself and loses around 20% of its power. As a result, some heavy goods vehicles manipulate their exhaust system (for example using illegal electronic boxes) to avoid using AdBlue in order to reduce their costs. These "fraudulent" heavy goods vehicles then emit large quantities of nitrogen oxides (NOx) and contribute significantly to local air pollution.

Recent experiments with pollution radar have been successfully carried out in Europe (Austria, Denmark, Spain) in partnership with local or national police forces. The results showed that, on average, more than 50% of heavy goods vehicles identified by pollution radar were using a system to defraud the NOx reduction system.

The implementation of a pollution radar, whether on an ad hoc or periodic basis, also allows for optimized management of a captive fleet and offers several advantages to managers (public or private) of a vehicle fleet :

 

  • Identification of the most emitting vehicles in the fleet

  • Maintenance of targeted vehicles

  • Economic gains made by the company (on fuel consumption)

  • Raising awareness among employees and communicating with the public

  • Registration of the action in CSR approaches
