Want to get there faster? Turn off the traffic report and trust a computer to figure out your route. Researchers at MIT have designed the CarTel system, a small cell-phone sized computer that connects to a Web server and collects data about your speed and path from one place to another. It tells drivers where the traffic congestion is the worst, as well as alerts them to any maintenance troubles their car is developing. When data from many cars is compiled and compared, the computer crunches the numbers to decide which way to go. The system has already helped its creators cut their commute time by 25% -– not too shabby, considering Boston has some of the worst traffic in the country. Though a similar product called Dash already exists, the CarTel will improve on historical data and use better algorithms to help guide you through your urban jungle.
