Still at the prototype stage, a new generation of intelligent cameras developed by RATP should soon make it possible to measure crowds on line 14 of the Paris metro in real time. A box soon installed at the entrance to Chatelet station will estimate the number of passengers in each train, car by car. This experimental phase will last three months, from mid-June to mid-September, and will allow the system to be perfected before its large-scale deployment on other stations on line 14, but also on the RER B, and even other routes. Ile-de-France railways.
At the origin of this technological novelty, artificial intelligence. “A first algorithm will cut the structure of the train. Doors, windows, etc… And a second algorithm will, at the window level, count the number of silhouettes, to be able to determine a density of people and therefore a level of affluence,” explains Gilles Tauzin, director of the innovation of the RATP group, interviewed by FranceInfo.

Once the information has been collected, it will be transmitted to the platforms via screens, so that travelers can anticipate and position themselves where there are the fewest people. “The level of affluence will be materialized with, at the same time, a color code, green, orange, or red, depending on the level of affluence in each of the cars, but also a number of silhouettes, which will also allow people who do not distinguish colors to be able to know what the information is,” specifies Gilles Tauzin.
