Here’s a TED talk from Janette Sadik-Khan, the New York City Transportation Commissioner, on how they’ve transformed New York City streets over the past several years.
I love the Citi Bike program (especially the data), which she helped introduce, so it is interesting to hear her talk about how and why the program was started. There is also an interesting article on Sadik-Khan on the TED blog which provides some additional insight into her and the various programs she’s helped develop.
