Philadelphia - "In case you haven't been wandering around the east side of Broad Street in Center City recently, the neighborhood has been sprouting refrigerator size boxes at every signalized intersection.
They're part of a Streets Department project to digitize the traffic signals throughout the city, but thanks to the Department of Homeland Security the new system is three times the size of the old pole-mounted controls, requiring a 67-inch free-standing box.
The reason? The boxes were made bigger so they could hold the computer equipment for a future surveillance network." Inga Saffron - architecture critic for the Philadelphia Inquirer.
