Public transport in the Lille metropolitan area

An extended network for a healthier, more pleasant urban area

In 2019, the European Metropolis of Lille (MEL) has adopted a master plan for transport infrastructure, which provides for a major increase in collective mobility in order to improve accessibility, attractiveness and air quality in the conurbation.

As part of the TELIO consortium, Artelia is assisting the MEL with the management of two key projects in this urban development programme, the creation of 75 km of tramway lines and high service level buses.


Through its new transport infrastructure master plan, the Lille European Metropolis intends to strengthen sustainable mobility by offering new combinations of reliable, high-frequency public transport. At the heart of the project is the creation of 50 km of tramway lines and 25 km of Bus Rapid Transit (BRT) lines to complement the existing network. Combined with various public space redevelopments, these mobility projects are part of the Metropole’s policy to protect the environment and tackle climate change. By strengthening public transport and associated active mobility, MEL aims to reduce emissions and concentrations of atmospheric pollutants from road traffic.

In partnership with Transamo, as part of the TELIO consortium, Artelia has committed to helping MEL manage the entire programme over a 10-year period, covering all the necessary aspects (administrative, technical and financial), from the development of the programmes to the completion of the works. A wide range of expertise is being mobilised to provide this assistance: steering of studies and implementation, assistance with grant applications and land acquisitions, support with transport systems, the choice of rolling stock and station furniture, the creation of maintenance and storage centres, etc.

Bordeaux Métropole’s climate policy has been structured around three main questions: What are the impacts of climate change on the region (worsening heatwaves, river and sea risks, availability of water resources, etc.)? What are the levers that the Metropolis can use to address these issues and improve the region’s resilience? How and when should these levers be activated with local partners?

To support the local authority in its approach, our teams carried out a vulnerability assessment, evaluating the area’s exposure to different climatic hazards and studying its sensitivity from several angles (urban areas, buildings, water resources, biodiversity, public health, etc.). They then organised and led a strategy seminar with the city’s departments to prioritise the issues and draw up an adaptation strategy for the area. They then worked with the Metropole’s technical departments and partners to define a comprehensive action programme, incorporating current projects (such as the flood prevention plan).
