Ever since cars became the most dominant form of transportation in the world, cities have been transformed drastically to accommodate travel demands. Since then, the demand for additional vehicular capacity has been increasing steadily. However, since 2005, demand has been decreasing. This has baffled engineers, who have had to focus on more sustainable solutions.

Ricky Angueria, a graduate student from Puerto Rico, will discuss changes in the design of cities to accommodate the demand for more environmentally friendly routes of transportation.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
