These are the first effects of the 30 km / h limitation on almost all the streets of Paris.
Since August 30, according to data collected by the Coyote road application and made public by RTL on Friday, vehicles driving in the capital have reduced their average speed by one km / h and are 4% less numerous than before.
Regarding speed, the structural difficulties in driving in Paris mean that motorists were already traveling at less than 30 km / h on average before the implementation of the measure.
Over the first fifteen days of September, this speed fell from 23.7 km / h to 22.7 km / h, a little more than 4% decrease.
A fundamental trend
The objective of the mayor of Paris is also that people move other than by car, such as by bicycle or public transport, the 4% decrease in traffic could go in this direction.
But it is impossible to know whether this decrease translates into trips made differently or which ultimately do not take place.
“At 30, we drive either over-revving in 2nd (and polluting more), or under-revving in 3rd.
Cars are not made for this speed, "said Parisian Pierre Chasseray, general delegate of the association 40 million motorists.
Limiting the speed to 30 km / h in the center of certain cities, or even in their entire perimeter, is a trend that is gaining ground in recent years. Grenoble (Isère) was a pioneer in 2016. Bordeaux (Gironde) will follow suit in January 2022. Clermont-Ferrand (Puy-de-Dôme), from December 1, and Lyon, in spring 2022, will also expand the list of the cities concerned.
