- These sensors have been deployed gradually since June 25, for a period of one year.
- With fixed and mobile sensors, "we will thus have hour by hour and on all axes, the level of pollutants", Jean-Philippe Dugoin-Clément, vice-president of the region, in charge of the operation.
- In parallel with these measures, postal workers will collect the feelings of Ile-de-France residents on the air they breathe.
It is an experiment which is intended to be “new”. The Ile-de-France region, in partnership with Airparif, has started to deploy sensors on vehicles and buildings of the Post Office in Paris and its outskirts to measure pollution in the Ile-de-France region. A device that is part of the plan “Let's change the air in Île-de-France”, adopted in June 2016. Objective: “Better understand this pollution, and eradicate its roots”.
On March 16, after a call for tenders in which seven consortia participated, the consortium led by the company Geoptis - a subsidiary of the La Poste group - was named the winner of the project by Airparif. The company is therefore now in charge of the deployment of 600 fixed and mobile micro-sensors, on a regional scale, and of the implementation of awareness-raising actions among Ile-de-France residents to determine their perception of the issue of air quality. Jean-Philippe Dugoin-Clément, vice-president of the region, in charge of the operation, is pleased with these new tools of “measurements, knowledge and perception”. “It's a large-scale experiment,” he says.
"Real mapping in real time"
"It is a means of having real-time knowledge of air pollution in Ile-de-France thanks to 100 fixed sensors on the buildings of the post office and 500 mobile devices deployed on vehicles which run almost daily" , he explains to 20 Minutes. Specifically on letter carriers, Stuart courier bikes, as well as utility and heavy goods vehicles. And to specify: “We will thus have hour by hour and on all axes, the level of pollutants. We are going to look for fine particles, nitrogen oxide and ammonia. It is a real mapping in real time ”. The data produced every 10 seconds will in fact be processed and analyzed with a view to being integrated by Airparif into its maps, in real time.
These sensors have been deployed gradually since June 25, for a period of one year. “We will have a review at the end of this period to see if we continue. But we are still on the idea of wanting to work over time, ”comments the vice-president of the region.
"Collect the feelings of Ile-de-France residents"
In parallel with these measures, postmen will collect the feelings of Ile-de-France residents on the air they breathe, through a questionnaire co-designed by Airparif and the Île-de-France region with 2,500 people. The goal is to combine these results based on feelings with objective data from surveys in traffic. “It makes it possible to objectify the data”, indicates Jean-Philippe Dugoin-Clément.
In addition, in this "same desire to involve Ile-de-France residents in this vast operation", a third component will consist of training citizens in the reporting of anomalies having an impact on the air and their environment, such as odors or even respiratory problems via an application. Three thousand people should join this panel. Total cost of the operation: 1.5 million.
