With urban sprawl, the demand for mobility is increasing, resulting in congestion, pollution, and degradation of the quality of life in cities, which is becoming a public policy issue. Mass transportation is one of the solutions to decrease the excessive use of cars. The Covid-19 pandemic and repeated lockdowns have had a positive effect, roads have been emptied and people have rediscovered walking and cycling. This reduction in cars on the road has led to a sharp reduction in pollution. With the return of cars and the lack of appropriate infrastructure, cycling in the city may seem unsafe especially with the dominance of cars' presence on the roads. However, this first experience of cycling has been memorable and appears to have been deeply appreciated.

With this in mind, this seminar is being held to exchange and present the necessary recommendations so that effective solutions and countermeasures can be proposed, taking into account the specificities of each city: financial, logistic, existing networks, strategies already in place, etc.
