New technology will have a dramatic impact on cars and highways in the 21st century.
With the aid of advanced technology, smart cars will be so designed that they can help eliminate traffic accidents, determine their own precise locations and warn of traffic jams.
GPS and “telematics” will make it possible to build smart highways, which will benefit us in more than one way.

Global Positioning System (GPS)
GPS is a satellite-based navigation system made up of a network of 24 satellites placed into orbit (轨 道)by the U.S. Department of Defense (国防部).
applications, but in the 1980s, the government made the system available for civilian use (民用). GPS works in any weather conditions, anywhere in the world, 24 hours a day.
