Aim

To smooth traffic flows

of Rio, 4th most
congested city in the world

Solutions

  • 650 cameras

  • over 600 km

    of optic fibre

  • 1 automated

    control centre

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.

Automating traffic management

In Niteroi, a city of 500,000 inhabitants on the other side of the bay of Rio, this efficient traffic-management system takes on an extra dimension.

High-tech monitors combined with smart cameras have been positioned in the densest parts of the city. The control centre of these installations manages traffic in real time by switching traffic lights from red to green without human intervention. Motorists are also informed in real time of how long their journey will take, by means of boards with variable messages. The result: traffic is streamlined according to data received and analysed by the control system.

 

The main objective of this programme is to reduce travel time, but we also expect to see a drop in traffic-light maintenance costs and fuel consumption, as well as polluting gas emissions and the number of accidents.”

Rodrigo Neves, Mayor of Niteroi

And tomorrow ?

In Rio, ENGIE has been entrusted with the mission of adapting Maestro to an urban tunnel. All the tunnel’s infrastructure (lights, ventilators, emergency exits, etc.) will be linked to Maestro and controlled remotely, thus improving safety.
