Milan isn’t the only one in Europe slowing down. From Grenoble, a Brusselsas far as Barcelona, Berlin and London (in some areas) several cities have introduced or are moving towards speed limits 30 kilometers per hour in the urban area, as planned by the Lombard capital under the junta 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 – are swingespecially on the reduction ofnoise pollution. The reduction of traffic accidents and data on life quality in other cities, however, they bode well.
Paris and the rest of France – One year after the introduction of zone 30 in most streets in the center, the average speed data is a 12.9 kilometers per hour in September 2022 in the capital, it seems disappointing. The drop from the same period of 2021 was actually just around1.5%, according to the Observatoire parisien des mobilités, without a significant decrease in road accidents. The reduction in noise pollution is also inferior to expectations. Is for the environmental councilor of the Greens David Beliard has already shrunk over 3 decibels In the noisiest city in Europe, the Bruitparif Observatory estimates only a -1.4 decibels. The traffic though he has not suffered the new speed limit. on the other hand is diminished, 3.3% over the year and 8.9% over the two years. However, to assess the change in such cases, we must not look at the “average speed” – explained the Mayor of Grenoble in an interview with LCI Television. Eric Piole – What is really changing is the approach to center urban. The way of paying attention to others, especially to pedestrian and who uses it bicycle“. The French city has also been zone 30 since 2016. The average speed initially fell by just 1.6 kilometers per hour (from 18.9 to 17.3). The reduction of mortality related to traffic accidents, however, had touched 70%as well as a Lille and nantes. Its dimensions (425,000 inhabitants with neighboring communes) are obviously smaller than Paris, but its quality of life and its environment have earned it the title Green Capital and a loan from 350,000 euros by the European Commission.
Zurich and Brussels, two successful experiments – A recent survey of zones 30 and 40 in the city has generated great satisfaction among the city’s residents Town Swiss. Travel times have increased slightly, from 10 to 30 minutes. But the border – explains a report by the European Environment Agency – has made us collapse noise pollution by one spot on average between 3 and 5 decibels. By 2030, the city plans to add 120 kilometers of slow roads and another 30 kilometers with restrictions only nocturnalImproving the quality of sleep and thus the health of 950 thousand People. In addition, since the introduction of the first zone 30 in 2000, the car accidents I am down 15% and 27% injured. In Austria instead in the nineties only those 44% of citizens agreed to the speed limit of 30 kilometers per hour. Today the consensus for the measure increased to 80%. TO Graz, since 1986, has gradually halved road deaths and reduced noise pollution by 2 decibels. The experiment seems to have worked Brussels. The limit was introduced in the Belgian capital in early 2021. Half a year later there was a reduction in the average speed of between 7% and 19% with remaining driving times untouched. However, the real victory, at least in the short term, was the reduction in traffic accidents (-20% in the first two quarters). For comparison: In the first four months of 2021 there were 635 compared to 814 in the same period last year. The number was already declining: at the end of 2020 it had been only 708, but mortality also marked a setback at -25% in the first six months since the measure was introduced. the Noise perceived, but it is almost halved with a noise reduction between 2.5 and 3.9 decibels.
Pollution also slows in Bilbao – Also in Spain Barcelona and Valencia You will take on the limit of 30 kilometers per hour. However, the longest-lived case is that of Bilbaoin the north of the country: in 2020 it extended the provision to its entire territory and received the in May of the same year European award for mobility. Indeed, the Basque city has benefited from years of reduced mobility (which was already in force on 87% of roads before the introduction of zone 30), with few road accidents and one reduction of pollutants harmful for respiration: del 3% of NO2 (nitrogen dioxide), del 9% NOX and del 12% PM10 or particulate matter. The movements a Cycles In addition, they have increased from 320,000 in 2018 to 1,791,000 of 2021.
