Motorized traffic is on the increase, especially in urban areas, resulting in economic and environmental costs relating to the considerable urban density. By connecting road infrastructures to communication technologies and limiting the use of individual means of transport, urban congestion can be reduced.
Niterói, Brazil: a 30% reduction in traffic
ENGIE has installed a command center that acts on road traffic in real time thanks to hi-tech controllers linked to smart cameras in the city’s ten most traffic-dense zones. It allows traffic signals to pass from red to green without human intervention. ENGIE has also developed a modular digital platform that links the 22 closed circuit cameras, 14 variable message panels and traffic controllers using 55 km of optical fiber cables. Car drivers receive information on their journey times thanks to variable message panels connected to the social networks. This automated management makes it possible to reduce residents’ travel time, the cost of traffic signal maintenance, fuel consumption, polluting emissions and the number of accidents.
Key figures:
- 30% reduction in road traffic
- 22 cameras
- 14 variable message panels
- 55 km of optical fiber cables
La Baule, France: a platform for smart management of urban space
Following the energy performance contract signed in 2016 for the modernization of its public lighting, the city of La Baule-Escoublac wanted to pursue the transformation of its territory using new technologies. To enhance the appeal of the seafront, improve (especially during the tourist season), optimize parking management by encouraging the turnover of cars and ease access to stores, the city appealed to ENGIE. We therefore developed an innovative parking management system and a digital platform for visualizing and planning public space. The various types of equipment connected (information panels showing spaces available, touchscreen parking meters, short-term parking terminals, etc.) will help improve the traffic flow, reduce the search time for parking spaces and reduce traffic pollution. Inhabitants, storekeepers and tourists will all enjoy greater comfort.
Key figures:
- Smart sensors control street lamps remotely and make street lighting more efficient and economical
- Energy-saving commitment of 53.8%
- 16,000 inhabitants
- 4-year partnership
- 50 information panels to guide drivers
- 20 parking lots progressively renovated and equipped
- Approx. 80 digital parking meters
- Approx. 30 short-stay terminals connected
Rio de Janeiro: 30% reduction in response time when an incident is detected
In order to improve traffic flow in Rio (the world’s fourth most congested city) and improve road safety, ENGIE has designed a vast smart and automated network for urban traffic flow management, using a single interface that centralizes and controls data from multiple sources (radios, cameras, alarms, etc.). ENGIE has also installed more than 650 cameras throughout the city to collect real-time data on road traffic flow and improve response time in the event of an incident. The Maestro system incorporates cameras, radars, radio links, control of traffic signals and street lights and real-time message display. It captures data in real time and feeds the city’s operations center to optimize road traffic.
Key figures:
- Over 650 cameras
30% reduction in response time when an emergency is detected.
