Book excerpt: The research presented in this book highlights the relevance of centrality in travel behaviour and in more sustainable travel choices. Different operational forms of the centrality concept are revealed as important: it is shown that more sustainable travel can be influenced by several urban structure factors and that no particular combination is required as long as a certain level of centrality is provided. Finally, the book concludes that urban structure can, on one hand, constrain, and, on the other, influence travel choice.
