Changes to our urban landscape can seem daunting at times. But reader thm points us to this TED talk in which New York City Department of Transportation Commissioner Janette Sadik-Khan shows how New York quickly and cheaply changed its streets, sometimes with only some paint, to improve the experience for all users.

Some of these changes we already have here, such as bike sharing and parking-protected bike lanes. Others, like BRT, are in the planning stages. But are there places in the DC area that could benefit from conversion into a pedestrian plaza?
