In February and March 2020, the EDAR system was installed in several locations around Europe, including Frankfurt, Germany, to collect emissions data. The Frankfurt data collection took place over the span of 20 days. A Frankfurt newspaper, Frankfurter Rundschau, reported, “the real emissions from vehicles are to be recorded to improve air quality in the long term on this basis.” 

​

The article goes on to explain, "The Federal Environment Agency hopes that the measurement[s] will enable it to evaluate pollutant emissions as a function of energy requirements in the driving situation. The project is not related to the debate about driving bans and the updating of the air-pollution control plan. Rather, the real emissions from vehicles are to be recorded in order to improve air quality in the long term on this basis."

Remote sensing is an active technology used for the detection of real-world emissions from millions of vehicles in real time daily. EDAR performs this testing in an unobtrusive manner and allows for the observation of natural, real-world driving performance. Many cities in Europe have initiated trials to monitor the fleet to proactively identify anomalies or vehicles that are emitting excessive amounts of pollutants. EDAR can be installed in a multitude of scenarios, from gantries on multi-lane high-speed highways to commonly traveled city roads. In the case of Frankfurt, EDAR was installed on a busy city road using its transportable truss system.
 
Now, cities are recognizing that it is feasible to create effective air-quality schemes by implementing successful high-tech measures like EDAR. As Clean Air Zones expand, and an increasing number of Low Emission Zones and diesel bans appear, the need for a fair and accurate regulatory tool is necessary, now more than ever. Real-world data assists the government with making proper and beneficial decisions when it comes to future clean-air plans.
