The policy choices made by local authorities in terms of transport present major challenges:
- Infrastructure and transport networks are powerful tools for structuring space. The circulation of goods and people is an essential factor in the human and economic development of regions.
- Accessibility for the greatest number of people to public transport services (disadvantaged social classes, young people, disabled people, etc.) is an important factor in social justice.
- The development oftransport services which offer an alternative to the roads constitutes a major environmental challenge (limiting congestion, carbon footprint, etc.).
