DIJON, FUTURE MÉTROPOLE OF INNOVATIONThe first smart city à la française

5 min


Construction is helping this city in Burgundy to become smarter and more connected. Two keys to attracting businesses and serving its citizens better. The future is already here!
By Isabelle Godar


Making people’s lives easier, improving their living conditions, and supporting the community in its digital transition are the aims of OnDijon, the project for a smart and connected city that Dijon Métropole launched in 2015. Bouygues Energies & Services, a Bouygues Construction subsidiary, along with consortium partners Citelum, Suez, and Capgemini, has been contracted to design and set up a connected control center to supervise the urban equipment of 24 municipalities in the region and to operate and maintain it for 12 years. It has also been tasked with modernizing the public lighting, with a guarantee of a 65% reduction in energy consumption by the end of this €105-million contract. The first smart city project on this scale in France, it is bringing the introduction of organizational, technological, and economic innovations.

The first installation, which will become operational in the first half of 2019, is a new control center for the remote management of all urban equipment such as traffic signals, streetlights, and video surveillance systems. It will replace the six control centers in operation today, thus enabling the various municipal departments to work more efficiently with one another.

The project has been designed to get community members more involved in the life of their region. Soon, via their smartphone, they will be able to report problems they notice in the street – a street light that’s not working, graffiti on a wall, a garbage bag on the sidewalk... Comments Denis Hameau, a Dijon Métropole municipal councilor and a representative on the Higher Education and Innovation board: “The OnDijon project responds to our desire to promote participative democracy. With open data, we have the possibility of offering new digital services and giving citizens a large role in the decision-making process.”

The OnDijon project will put a single supervisor in charge of the remote management of all urban equipment in the 24 municipalities of Dijon Métropole. The data collected will be open data shared to create new, useful services for residents.

The large quantities of data generated in the management of public services represent opportunities for economic growth in the region. By adopting an open data approach, OnDijon enables companies in the digital sector to imagine new applications that will be useful to the city and its citizens in areas like connected mobility, smart services, information sharing, and many others. Bouygues Energies & Services is thus helping the municipalities in the metropolitan area to develop and encourage initiatives like the Fab Lab, Living Lab, and incubators, from which innovations for startups will come. “Innovation competitions will be held periodically by the community to give a boost to these initiatives,” explains Étienne Dumas, director of the OnDijon project at Bouygues Energies & Services. The experience gained in data management will make Dijon Métropole a model internationally. And the city is eager to share what it is learning with other regions and the academic world. Adds Hameau: “Several engineering schools will be coming to Dijon and offering courses related to these developments,” thus turning the city into a laboratory to explore what smart cities can be.

The Dijon Métropole project is totally unprecedented in scope...

It covers a very large range of services – mobility, security, lighting, streets, and interactive communication with users – all on the scale of 24 municipalities and over 250,000 inhabitants.


We are an infrastructure and urban equipment operator, and we don’t claim to be doing it all by ourselves,” says Mickael Suchanek, head of Urban Services at Bouygues Energies & Services. That’s why to position itself in relation to new smart city players in the energy, telecom, and IT sectors, it is relying on its capacity to choose good partners. At Dijon, it is teamed up with the EDF subsidiary Citelum, a specialist in urban lighting, along with Capgemini and Suez.

Two of the Group’s subsidiaries are also taking part in the project: C2S, for IT systems security, and Axione, which is installing 140 kilometers of optical fiber cable. “This is the first smart city project of this scale in France, and all communities are paying very close attention to it,” adds Suchanek. Bouygues Construction’s objective is to reproduce this model elsewhere in France and other countries, each time adapting it to the local context.
