congested city in the world

The city of Rio de Janeiro and its conurbation has invested in a smart traffic management system to relieve road congestion and make traffic smoother.

Rio de Janeiro regularly tops the list of cities with the most traffic jams in the world. The impacts of urban congestion are numerous: more fuel consumption, increase in CO2 emissions and the number of accidents… Steering and streamlining the traffic in a city of 1,255 km2 and more than 6 million inhabitants requires state-of-the-art equipment.


Managing traffic in real time

Cameras, speed checks, radio links, traffic- and street-light control, real-time message display… With the Maestro traffic-management system, ENGIE has now equipped Rio and its conurbation with an arsenal of solutions to steer and manage its urban traffic more efficiently.

In Rio itself, the Maestro system captures traffic data in real time and supplies the data to the city’s operation centres. Local officers can thus monitor the traffic situation in different parts of town, take note of accidents and intervene from a distance by mobilising the various technologies at their disposal.
