Public transport, a key factor in the attractiveness of territories

Mobility issues are closely linked to the transformations that our cities and metropolises are undergoing today. And the growth of the urban population over the past 50 years, which has been accelerating steadily, is one of the main factors driving urban change. According to the United Nations(1), it is estimated that by 2050, 7 out of every 10 people on our planet will live in urban areas. Against a backdrop of ever denser populations in our cities, what is the future for public transport? 
Public transport is a major factor in the development and attractiveness of territories, enabling fluidity of travel, while ensuring the safety and comfort of passengers. It is also a powerful lever for reducing carbon emissions and protecting the environment. In fact, public transport alone accounts for 27% of carbon emissions(2).
