A city is easier to live in when it's easy to get around. But getting around is hard in many cities, especially for people who rely on public transit.

Take buses, for example. They may not run when you need them. They might take too long. Or they might not even get to your neighborhood at all.

Transit operators, city officials and people in the federal government all hope that big data will help them change public transportation to get transit where it will be most used.

Back in 2012, something unusual got started in an alleyway in an already tightly developed part of northeast Washington, D.C.

On an 11th-of-an-acre lot next to a cemetery, behind a block of row houses, tiny houses started to go up. And not just one little house in backyard, like you might see in many places. The builders billed this as an urban tiny house community.

It takes anchors to keep neighborhoods lively — key restaurants and stores that draw people from far and wide. Walters Clothing in downtown Atlanta is a mom-and-pop shop that has that kind of magnetic attraction.

Washington, D.C., moved a big step closer this week toward building its own "bridge to the future." Two well-known design firms — OMA and OLIN — were selected as the winners of a competition to conceptualize the 11th Street Bridge Park.
