A highlight of the Wellington 2014 walking year was this talk from international walk researcher Daniel Sauter. Daniel spoke about the important 4 "I's" of walking - Inspiration, Identity, Infrastructure and Institutional arrangements. He noted the joy of walking and 'being' in a place, were as important in a liveable city as moving through spaces, and had some interesting research to show how we spend our time. He commented that he particularly enjoyed the debate during his presentation - thanks to those attending.
Here is the pdf of his presentation. I recommend watching the William H Whyte video clip too.
