Below I have linked to some more information on cities from Diana Lind and TED. She is one of the authors from TED City 2.0 whose essay I did not have time to discuss on my blog from Wednesday (https://jamesperegrine.com/2015/06/03/changing-cities-and-changing-lives/) but it is well worth learning more about.
Here is a blog post via the TED website: http://blog.ted.com/cities-without-highways-a-qa-with-ted-book-essayist-diana-lind/ the post is an excellent read on why highways hurt cities and their inhabitants. Additionally, her TED talk: https://www.youtube.com/watch?v=dec_gxEGmeI . She can be found on Twitter at https://twitter.com/dianamlind?lang=en .
I hope you find her insights valuable and I would love to hear what you thought about her suggestions.
