Freeway ban also in Franconia?

The german environmental aid association (DUH) has filed a lawsuit against the state of baden-wurttemberg in order to ban diesel vehicles from driving in freiburg. Only on thursday, the administrative court in gelsenkirchen ordered a no-driving zone in essen, which includes the busy autobahn 40, following a lawsuit filed by DUH. This means that the number of stretches of road closed to diesel vehicles continues to rise. Franconia is not an air paradise either: excessive nitrogen oxide levels are measured not far from the A 73 motorway. Especially around the frankenschnellweg in nurnberg. Could a piece of highway also become a no-go zone for diesel drivers in franconia??

Limit value at 40 micrograms

The affected section in essen cuts through a residential area, with houses only a few meters from the roadway. In 2017, an annual average nitrogen dioxide value of 50 micrograms per cubic meter ( µ g/m 3 ) was measured at this location. According to the 39. Federal immission control ordinance since 2010 but only 40 micrograms.

The conditions in nurnberg are similar: the measuring point "von-der-tann-strabe" is located only about one kilometer south of the frankenschnellweg. Yesterday, the peak value during the day was quite high at 91 µ g/m 3.

Varying environment

However: "a single value has no significance. An annual average is necessary and required by law", a spokesman for the bavarian state office for environmental protection (lfu) in augsburg explained in response to an inquiry. But even this value was too high in 2017, at 43 µ g/m 3 in nurnberg.

Anyone from bamberg or erlangen who now points the finger at nurnberg must take one thing into account: the location environment of the individual measuring stations is very different. The measuring points in bamberg and erlangen are almost idyllic compared to the busy von der tann road in nurnberg. But this mix is desired. "The measuring stations are located at sites with different characteristics – close to traffic, urban and rural backgrounds. That’s what the law says", reports the lfu spokesman.

DUH with "passive collectors

German environmental aid has long criticized the lack of data on air quality in many places with high traffic volumes. A few months ago, it therefore introduced so-called "passive collectors" inserted. Volunteers install measuring tubes on lampposts and street signs where there is a lot of traffic. The measurement method is very simple, but proven.



A swiss laboratory has carried out the evaluation. The result in the region: in addition to nurnberg, the values in furth were also significantly above the limit value – however, measurements were only taken for one month.

Will the air for diesel drivers in the region now be dark, if someone complains?? Hardly. If the required limit values are exceeded, the municipality concerned will first draw up an air pollution control plan. Nurnberg has done that. One of these has been in force since 2004.

Trend: values are declining

Among other things, this plan aims to make traffic flow more smoothly by cleverly switching traffic lights and to restructure the municipal vehicle fleet to reduce emissions.

With success. NO 2 levels have fallen in recent years. Uberall in bavaria. Wurzburg even managed to stay below the limit in 2017. But if you look at the values measured yesterday, you can see that the situation remains critical.
