A system based on the recovery of data from connected vehicles and then their interpretation by an artificial intelligence algorithm will be able to regulate the duration of a red light almost instantly.
For more than 20 years, Toulouse has had an intelligent traffic light management system, which is managed by the Campus Traffic center, PC Capitoul, located on Boulevard d’Atlanta. There, operators have a global view of traffic and can intervene as soon as a problem is reported. The system is automatic, with nearly 2,000 underground sensors. At certain intersections, at the foot of the lights, in the ground, magnetic loops record and analyze the speeds of passing cars. But operators can take control. They analyze blockages and can make the decision to change a light to red or green depending on needs. The rhythm of the lights is adapted every day to the flow of cars entering and leaving the city.
Artificial intelligence stronger than humans?
Thus, in the morning, from 7 a.m., the green lights are longer for the most numerous motorists traveling towards the center. And vice versa in the evening. An already efficient system that artificial intelligence will undoubtedly revolutionize. Toulouse is one of the first large cities in France which is preparing to test on four red lights on the Narbonne road, a device developed by the company Wisp solutions to coordinate the lights and thus reduce waiting times at intersections. from Impasse Marfaing, Chemin de la Bourdette, Chemin des Sauges and Allée du Lieutenant Lucien-Lafay. A device based on the recovery of data from connected vehicles and then their interpretation by an artificial intelligence algorithm will almost instantly regulate the duration of the red light to better take into account the passage of priority vehicles, buses or emergency vehicles. The test will perhaps make it possible to see whether humans or artificial intelligence are more effective…
700 traffic lights in the Toulouse metropolis
The Toulouse Metropolis and its 37 municipalities have nearly 700 traffic light intersections, mainly (540) in the central city. When Paris has 1800, Lyon 1700, and Bordeaux which wants to eliminate 200, more than 900… Toulouse’s strategy, in the long term, is to transform around thirty into roundabouts. The metropolis therefore wants to reduce their number, six were dismantled last year and five others will be dismantled by the end of the year, but in a pragmatic way.
