The European Metropolis of Lille is committed to taking concrete measures to reduce greenhouse gas emissions and fight climate change. For many years, it has implemented many concrete actions, such as the establishment of cycle paths, the promotion of eco-mobility, or the implementation of awareness campaigns among residents to reduce the share of gas emissions on its territory. The main objectives of the project are to: - limit air pollution and greenhouse gas emissions, - encourage the use of the most virtuous means of transport for commuting: public transport, carpooling, cycling, etc... - relieve the main saturation points of the agglomeration of a few percent of their traffic volumes during peak hours in order to move from a saturated to a dense situation, sufficient to contribute to a clear and visible improvement in the level of service of the targeted infrastructures. -improve the reliability of journey times of road transport infrastructure users.
