Tempo 30 in Berlin : The police controlled in the weekly rhythm

an Average of 124 metres long, the 85 main road sections, on which from July to a pace of 30 to apply for better air. In many cases, the line should be just long enough to get through the accelerator pedal from a speed of 50 kph to 30. – Less Gas also produces less exhaust gas would be met on the one hand, the Intention of the air pollution, but on the other hand, the question of the extent to which these speed limits at all will be accepted – especially since you are supposed to apply to the clock, so at night, when there is little traffic and no congestion.

A clear indication to deliver evaluations that informed the police on the daily mirror inquiry. So it was in June 2018, after the first month, with regular tempo controls on the Leipziger Straße, the so-called exceed the rate, so the fast driver rate, with 3.5 percent exemplary. Because of the city-wide average for roads with speed 30 deck 9.4 percent.

transport moral but a side-effect of the duration of traffic jams

Now, a similar question showed a very different picture: Although no statistics is available, according to the police, but "while the identified Exceedances were up to the end of the year 2018 in the Leipziger Straße, due to the high volume of traffic is very low, were you in the Potsdamer Straße and on the Tempelhofer Damm, where if the speed limit is 30, about the average value of the previous year for comparable roads in the urban area with a speed reduction to 30 km/h.“

On the main and Kantstraße, the fast drivers had rates even above this average value. What looked to model traffic morale, was more of a side-effect of the duration of congestion in the Leipzig. The police controlled the Tempo 30-try routes according to information of the Bureau in the weekly rhythm of the car changing times with Radar and hand lasers.

to order How much is the speed limit really, for the test tracks after the expiry of a year, say – and the fact that the nitrogen dioxide pollution, the annual mean is the key size. From earlier investigations of the environmental administration, it is known that the NO2 levels with the introduction of Tempo 30 to five to seven micrograms per cubic meter decreases air (the limit is 40).

No clear improvement of the NO2-values

These experiences were collected at Silberstein, shield, horn, and Beusselstraße, the measurement were compared to data from the three years before and after the introduction of Tempo 30 with those of other roads, without this Limit. So weather could be filtered conditional effects.

The traffic management refers to the fact that the administrative court accepted these findings "and the basis of its judgment of 9. October 2018“. As a consequence, the Senate would for the future Tempo-30-routes package, a reduction of five micrograms of NO2 per cubic meter of air accept. Whether the calculations are correct, measurements show.

For the Leipziger Straße, the NO2 balance of the past months shows no clear improvement since the introduction of the speed limits in April 2018. However, the burden of quite different factors: On cold winter days, you can tend to rise, because many of the diesel vehicles chokes then its exhaust gas cleaning or switch it off entirely – according to the producers, for the protection of motors. In the record summer of 2018 wind was, in turn, is often unusually quiet, so that the exhaust gas is also more able to accumulate.

No waiver on Diesel by driving restrictions

to abandon the planned Diesel-driving bans, according to the environmental administration, in spite of the on Thursday from the Bundestag adopted the Amendment of the Immission control act is not out of the question. Should be omitted in the case of a previous load of less than 50 micrograms of NO2 on driving bans – but it relates specifically to whole areas and not individual streets.

And as the area of Berlin is not the case under this provision, starting in 2018, six measuring more than 50 micrograms of NO2 in the year in the medium were measured.
