In this short video, Dr. Natalia Barbour introduces the challenges that are present in achieving sustainable transportation, namely in substituting car travel for other modes of transport, as well as making sure that remaining personal vehicle trips are powered by renewable energy. The topic will be discussed in more depth during a guest interview in the next section.

Key takeaways:

1. It is a great challenge to convince the general population to consider to switch from personal cars to other modes of transport in urban areas.
2. When traveling long distances, there are not many alternatives.
3. There has been a large amount of research to explore how socio-demographic factors influence travel behavior and mode choice.
