It is a phenomenon visible to the naked eye: there are more and more cyclists in the Parisian streets and the facilities are increasingly cramped. Failing to have become the “cycling capital of the world” promised by the mayor of Paris, Anne Hidalgo, use of cycle paths there has soared, doubling between 2022 and 2023 during peak hours. A trend, started in 2019 during the public transport strikes then in 2020 during the deconfinement, which does not go away. For the month of October 2023, there were twice as many bicycles passing through the sensors installed by the city as in October 2022.
This doubling, even tripling of attendance in certain places, does not surprise the deputy mayor in charge of mobility and public space, David Belliard (Europe Ecologie-Les Verts, EELV): “We already knew that the use of bicycles had gone far beyond simple fashion. (…) While the weather has deteriorated in Paris in recent weeks, we have again recorded attendance records. »
“In mobility more than elsewhere, the central question is supply rather than demand”estimates the elected official, who assures that the municipality has “massively amplified the supply of infrastructure” since his re-election in 2020, building protected bike lanes and installing parking spaces. This is the principle of induced traffic: when an infrastructure is created or improved, it generates an additional volume of traffic, regardless of the mode of transport concerned (road, rail, bicycle, walking, etc.).
However, between the delay on the “bike plan” and that taken on the perpetuation of the coronapists, according to the Cycling Plan Observatory set up by the Paris en saddle association, the Socialist Party-Communist Party-EELV municipal team has only completed 21% of the project, while half of its second term has passed. A delay that Mr. Belliard recognizes and partly attributes to the complexity of the upstream procedures, “because we do not have control over all public space, there are still some difficulties with the police headquarters”.
More bikes than cars during rush hours
Other teaching of road counting statistics; during rush hours, bicycles outnumber cars on certain representative roads in the capital. On Avenue de Flandre, Boulevard Voltaire and Boulevard Magenta, the average never exceeds 384 motorized vehicles per hour on the central part of the road, compared to 537 bicycles on the cycle paths in September and October.
The roads are saturated during rush hours while relative fluidity remains on the cycle lanes, in particular due to the low ground occupancy of bicycles. A bicycle requires approximately 1.5 square meters of floor space to transport a person, five times less than a car (7.5 square meters for the best-selling SUV, the Peugeot 2008) – in Paris and Ile-de-France. France, there are 1.1 people on average per vehicle.
The latest figures available, dating from 2021, indicated that the bicycle represented 5.6% of trips in Paris, compared to 9% for the car. The “rebalancing” policy carried out by left-wing municipal majorities since Bertrand Delanoë has reduced intramural automobile traffic by around 45% since 2001.
