Star cities continue to develop their urban centers — but why are they so empty? By controlling the curb, cities can control the future. The next leader in water management could be...Los Angeles?

Nashville is not the model boomtown: As rising star cities continue to develop thier urban cores, visitors and observers find these places are not bustling with pedestrians, but rather wide streets and empty sidewalks.

Quote of the Week

"The video, it’s talking to you. Before, you would just get numbers. Now, we know where they are crossing. We know when they are crossing. We know how many people are driving through a red light. That’s going to help us inform a lot of our work in the next few years."
