Milan is not the only one in Europe to slow down. From Grenoble, a Brusselsas far as Barcelona, Berlin And London (in some areas), several cities have adopted or are moving towards the speed limit 30 kilometers per hour in the urban area, as the Lombard capital plans to do under the junta of Beppe Room. The most discussed case is that of Pariswhere the results of the measure – introduced by the socialist union Anne Hidalgo since July 2021 – have been swingingespecially on the reduction ofnoise pollution. The reduction of road accidents and data on life quality in other cities, however, they bode well.

Paris and the rest of France – One year after the adoption of Zone 30 in most of the streets in the centre, the data on the average speed a 12.9 kilometers per hour in September 2022 in the capital it may seem disappointing. The drop compared to the same period of 2021 was in fact only by1.5%according to theObservatoire parisien des mobilités, without a substantial decrease in road accidents. The reduction of noise pollution is also inferior to expectations. If for the Councilor for the Environment of the Greens David Béliard has already shrunk by 3 decibels in the noisiest city in Europe, the observatory of bruit parif estimate only one -1.4 decibels. The traffic though he didn’t suffer of the new speed limit. On the contrary is diminished, 3.3% over the year and 8.9% over the two years. To evaluate the change in cases like these, however, one must not look at the “average speed – he explained in an interview on television Lci the mayor of Grenoble, Eric Piolle – What really changes is the approach to center urban. The way to pay attention to others, especially to pedestrians and who uses the bicycle”. The French town has also become Zone 30 since 2016. The average speed initially dropped by only 1.6 kilometers per hour (from 18.9 to 17.3). The reduction of mortality linked to road accidents, however, had touched the 70%as well as a Lille And Nantes. Its dimensions (425,000 inhabitants with neighboring municipalities) are obviously smaller than those of Paris, but its quality of life and environment earned it the title of Green Capital and a loan of 350 thousand euros by the European Commission.

Zurich and Brussels, two successful experiments – A recent survey of Zones 30 and 40 in the city garnered much satisfaction among residents of the small town Swiss. Journey times have slightly lengthened, from 10 to 30 minutes more. However, the limit – explains a report by the European Environment Agency – has allowed us to break down noise pollution by one digit on average between 3 and 5 decibels. By 2030, the City plans to add 120 kilometers to slow roads and another 30 with limits nocturnal onlyimproving the quality of sleep and therefore the health of 950 thousand people. In addition, throughout Switzerland since the introduction of the first Zone 30 in 2000, the car accidents I am dropped by 15% and 27% injured. In Austria instead in the nineties only the 44% of citizens approved the limit of 30 kilometers per hour. Today the consensus for the measure rose to 80%. TO Graz, since 1986, has progressively led to halving road deaths and reducing noise pollution by 2 decibels. The experiment seems to have worked a Brussels. In the Belgian capital, the limit was introduced at the beginning of 2021. Six months later, there was a reduction of between 7% and 19% in average speed, with journey times remaining unaffected. However, the real victory, at least in the short term, was the drop in road accidents (-20% in the first two quarters). To give another term of comparison, there were 635 in the first four months of 2021, against 814 in the same period the year before. The number was already declining: there had been only 708 at the end of 2020, however, mortality also marked a setback, with -25% in the first six months since the introduction of the measure. The noise perceived instead it is almost halved with a decrease in noise between 2.5 and 3.9 decibels.

Pollution also slows down in Bilbao – In Spain too Barcelona And Valencia they will adopt the limit of 30 kilometers per hour. The most long-lived case, however, is that of Bilbaoin the north of the country: in 2020 it extended the provision to its entire territory, receiving, in May of the same year, the European Award for Mobility. The Basque city has actually benefited from years of reduced mobility (which was in force on 87% of the streets even before the introduction of Zone 30), with few road accidents and a reduction of the pollutants harmful to respiration: del 3% of NO2 (nitrogen dioxide), del 9% NOX and del 12% PM10, or fine dust. The movements in bikes moreover they have gone from 320 thousand in 2018 to 1,791,000 of the 2021.
