WASHINGTON — Federal accident investigators today recommended the government set performance standards for new safety technology that allows cars and trucks to talk to each other and then require the technology be installed in all new vehicles.

The National Transportation Safety Board made the recommendation today in response to fatal school bus accidents at intersections in New Jersey and Florida last year.

Vehicles equipped with the technology can continuously communicate over wireless networks, exchanging information on location, direction and speed 10 times a second. A computer analyzes the information and issues danger warnings to drivers, often before they can see the other vehicle.

NTSB officials said the technology holds great promise to reduce deaths and injuries caused by crashes at intersections.
