Get ready, Brazil: a true revolution in traffic may be on the way, and it goes by the name of “smart traffic lights.” These innovative signaling systems, equipped with sensors, cameras, and artificial intelligence, promise to transform the urban experience, alleviating traffic jams, reducing pollutant emissions, and providing much safer and more efficient mobility. With the new proposal of Bill 3048/24, these traffic lights may soon be mandatory in cities with more than 150 inhabitants, marking a new chapter in Brazilian urban mobility.
These smart traffic lights are designed to operate adaptively, adjusting the signal timing based on the flow of vehicles and pedestrians, rather than based on a fixed schedule. Imagine, for example, that during peak traffic during rush hour, the system automatically increases the green light time on the most congested roads. Similarly, if an emergency ambulance is approaching, the signal prioritizes its passage, avoiding critical minutes.
How smart traffic lights work and why they can improve traffic
The basis of operation of traffic lights intelligent lies in its connectivity and adaptability. Equipped with state-of-the-art sensors and cameras, these devices monitor traffic in real time. If traffic congestion builds up in one direction, the traffic light stays green for longer, reducing waiting times and allowing traffic to flow more quickly. All of this is done using artificial intelligence technology, which also allows them to integrate with larger data networks and communicate with remote control systems via a 5G connection.
The system also facilitates maintenance and ensures constant efficiency. Connected via fiber optic cables, these traffic lights can detect malfunctions and request automatic repairs, reducing traffic interruption times.

Growing urbanization and urban mobility challenges
In the face of growing urbanization and the expansion of vehicle fleets, traffic in Brazilian cities increasingly demands modern and efficient solutions. In São Paulo and Curitiba, the experimental installation of smart traffic lights has already demonstrated the potential to reduce traffic jams and offer a safer experience for drivers and pedestrians. Internationally, cities such as London, New York and Singapore have also adopted this technology, reaping results that point to a more sustainable and efficient traffic model.
Deputy Clodoaldo Magalhães, one of the project proponents, believes that smart traffic lights are a viable solution to the problems of urban mobility in Brazil. According to him, this technology can not only improve the flow of vehicles, but also bring more safety and quality of life to the inhabitants of large cities.
Financing and partnerships to enable the installation of smart traffic lights
For smart traffic lights to become a reality throughout Brazil, Bill 3048/24 provides for a specific line of financing with the National Bank for Economic and Social Development (BNDES), in addition to federal resources aimed at urban infrastructure and the possibility of partnerships with public and private entities.
These funding sources are organized into three main pillars: Funding specifically targeted at the installation of smart traffic lights. Resources already earmarked for the development of cities. Agreements that can accelerate the implementation of the technology.
Impact of smart traffic lights on Brazilian urban mobility
The introduction of smart traffic lights could be a game changer for urban mobility in Brazil. In addition to improving vehicle flow, these devices promise to reduce environmental impact, as they reduce the emission of polluting gases by avoiding unnecessary stops. Another point is the contribution to safety, allowing pedestrians and drivers to coexist more harmoniously in urban spaces.
With this advancement, Brazilian cities have the opportunity to align themselves with a more sustainable and efficient traffic management model, following the global trend of modernizing mobility. Ultimately, mandatory smart traffic lights can redefine traffic dynamics, offering a safer, more fluid urban environment that is adapted to the needs of the future.
For many, these new devices may seem like a detail in urban routine. However, for those who live with the chaos of traffic in big cities on a daily basis, the arrival of smart traffic lights could mean a real transformation in quality of life, promising to bring organization and safety to Brazilian public roads.
