The Long Beach Press Telegram reported on an interesting event that occurred on the 110 Freeway last week. According to the story, three big rigs navigated traffic along the freeway without the assistance of a driver. The Volvo big rigs could communicate with each other, which is one of the key factors that experts hope will increase the safety of commercial transportation in addition to reducing pollution and increasing energy efficiency. The project, a partnership between Volvo Group of North America and UC Berkeley Partners for Advanced Transportation, is sponsored by the U.S. Department of Transportation and Caltrans. The vehicles travel together so that they can respond to their surroundings and each other.
