Smart traffic lights are connected with Wi-Fi, and are the great promise to solve traffic problems in big cities. São Paulo is the largest city in Brazil and is also one of the most important in the world. In terms of traffic, SP has a fleet of more than 8 million vehicles that run for 17 thousand kilometers.

With this, there are approximately 6.5 thousand crossings in São Paulo, while only 1.2 thousand traffic lights are connected, and only 600 have remote actuation capacity and intelligence applications.

The idea is to bring intelligent traffic lights to optimize the management of urban mobility. A project template is being developed to revamp the entire system by making use of the technology, putting Wi-Fi hotspots at traffic lights, and thus enabling the creation of an Internet of Things (IoT) system.

With smart traffic lights, there will be a kind of dialogue between them, the vehicles and the roads, bringing more efficiency to the traffic lights, more quality to the traffic of the city and, consequently, more security also. This “dialogue” is called a “green wave”, and consists of the synchronization of smart traffic lights according to the flow of vehicles.

Smart traffic lights are directly linked to the concept of smart cities that aim to connect the entire infrastructure of cities. Remember this interesting subject here, when we talked about it previously.
