About 60% of Parisian streets are already limited to 30 km / h. (Arnaud Paillard / Hans Lucas via AFP)

This is hardly a revolution, but it is a new step in Anne Hidalgo’s majority program to limit the automobile traffic. The lowering of the speed of all the streets of the capital to 30 km / h on Monday is the culmination of a process of more than fifteen years, which in fact concerned already 60â ????% of the streets of Paris.

However, exceptions will persist. By decision of the Paris police headquarters, some axes and avenues will remain limited to 50 km / h, in particular the boulevards des Marà © chaux, the avenue des Champs-Elysà © es or even the Georges Pompidou route. The peripheral boulevard will remain limited to 70km / h.

Since the pedestrianization of the bank tracks in 2016, the socialist mayor has multiplied the measures, often drawing inspiration from what is being done elsewhere. Because the capital is not the first city to have acted in this direction: Grenoble and Lille have already taken the plunge, and around 250 French cities have imposed the 30 km / h on the majority of their axes, which concerns 15â ????% of the French population.

To defend this lowering of speed, David Belliard, the EE-LV deputy in charge of mobility and the transformation of public space, responded this Sunday to the JDD. According to him, the measure meets three objectives: “to improve the safety of pedestrians”, “to significantly reduce noise”, and “to appease the city”.

One would have thought that the green election would highlight the ecological impact of the passage from 50 to 30 km / h, except that it is “contrasted” in the short term, according to a 2014 study by the Environment and Energy Management Agency (Ademe), both in terms of pollution and noise reduction. The institution nonetheless recognizes a beneficial effect in the longer term, by emphasizing “the appeasement of traffic” and “a better sharing between the different modes of travel (walking, cycling, car and public transport) ».

All with the blessing, it seems, of a majority of Parisians: 61% of them say they are in favor of the measure , according to an Ifop poll for Mister Turbo unveiled this Sunday by Le Parisien. Of those polled, 71% think it will be good for the safety of the most vulnerable, such as children or the elderly. Unsurprisingly, it is especially the Ile-de-France residents who seem to have trouble with this program. Only 39% of them said they were in favor of the project when the city launched its own consultation in fall 2020.

Because it is especially the inhabitants of suburbs who use their car in the capital â ???? Barely a third of Parisians have their own vehicle. The former can also count on the support of the right-wing opposition, which denounces a brutal measure. To which David Belliard responds simply that everything was written in the program which allowed the re-election of Anne Hidalgo and her allies environmentalists in 2020â ??? ?: “We do what Parisians expect of us, quite simply.”

Motorists’ defense associations are also headlong against this measure, which they see as a new anti-car offensive by the mayor of Paris. The fact remains that for the moment, the cities which have chosen the generalized zone 30 have not reconsidered their decision. In Grenoble, the measure taken in 2016 had the effect of reducing “accidentality in number and severity”, as well as motorized traffic by 9% for vehicles. Light vehicles and 20% for heavy vehicles, according to a study by the Center for Studies and Expertise on Risks, the environment, mobility and planning (Cerema).

The only certainty in the capital is that apart from the signs, the measurement should not change so many things for motorists: in 2019, they were driving at 11.9 km / h on average during the day, according to the Paris Displacement Observatory. Like what, there is still a little margin.
