Aim

To improve traffic fluidity

and road safety

Solutions

  • Over 650

    cameras installed

  • Over 600 km

    of optical 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.

With more than 6 million inhabitants, Rio de Janeiro features on the UN’s “major world cities” list. It’s also the world’s 4th most congested city. To improve traffic fluidity and road safety, Rio has now turned to ENGIE, which is supplying an automated, intelligent urban flow management system. It’s a major step towards the “Smart City”.

Unifying and co-ordinating the CCTV network

The collaboration between ENGIE and local government in Rio began with the deployment of a vast CCTV system and large-scale telecommunications network. ENGIE also installed the Maestro system in the city’s operations center. Maestro is an intelligent interface that centrally controls data from various information sources: radios, CCTV, alarms, user alerts, etc. It aggregates these diverse data flows to facilitate the day-to-day management of urban services and improves decision-making. In Rio, Maestro system provides a co-ordinated system for managing 650 cameras from a variety of manufacturers, located at sensitive points throughout the city.  The system was central to security measures at the 2016 Rio Olympics.

Managing traffic in real time

Not just cameras, but also radar, radio links, controls for traffic and street lights, real-time message display, and more. The Maestro system coordinates mumltiple aspects of urban traffic management. It captures traffic data in real time and supplies it to the city’s operations center. Local officers can use it to monitor the situation in different parts of town, taking note of incidents and intervening from a distance using the various technologies available to them.

Improving bridge safety

Situated between the sea and the mountains, Rio is home to many bridges, viaducts and tunnels. Such infrastructure is sensitive in terms of safety, poor visibility, narrow lanes and a lack of hard shoulders, which can make driving dangerous. In 2013, the city of Rio and ENGIE implemented an initial automatic incident detection solution in the Linha Amarela tunnel, one of Rio’s key arteries. The following year, the partnership continued with a contract to update the safety system on the Rio-Niteroi bridge, a structure nearly 14km long and 27m wide. This involved the installation of a set of sensors to monitor traffic, automatically detect incidents and digitally transmit information about them.

And tomorrow ?

In Niteroi – a city with half a million inhabitants located across the Bay of Rio – ENGIE is setting up a command centre which will make real-time traffic decisions. It will ultimately allow traffic lights to change from red to green without human intervention. Drivers will also be informed in real time of how long their journey will take, thanks to connected message boards. This solution is expected to reduce traffic congestion by approximately 30%.
