Ed Bacon competition examines Philly with driver-less cars

What would life in Philadelphia look like if cars, buses, taxis and other vehicles drove themselves around the city, communicating with each other and with the people who summon them to get to work or play?
This was the question tackled by 15 student teams competing in the Better Philadelphia Challenge – the student competition portion of the Bacon Awards, presented annually by the Philadelphia Center for Architecture. (140 teams from 80 schools and 35 countries registered for the competition, with just 15 producing and submitting a project for judging).
