Researchers at Massachusetts Institute of Technology have found a way to figure out when you're likely to blow through that red light you're fast approaching in your car.

By analyzing a vehicle's speed, deceleration, and proximity to the stoplight, the new algorithm can predict which cars will violate the most basic of traffic laws: red means stop. The MIT research team tested their development using traffic data gathered from a busy intersection in Virginia already rigged with a bevy of sensors and cameras as part of Department of Transportation funded study.

When applying the new algorithm to … Read more

The cars of the future will use vehicle-to-vehicle (V2V) and vehicle-to-infrastructure communication for advanced safety technology that will help them avoid accidents, but what about the old clunkers sharing the road with them?

To make sure all cars have this new capability, GM is working on an aftermarket device that could work in all cars to communicate road and traffic hazards with other vehicles.

Unprotected turns, inclement weather, and road hazards are scenarios that can lead to automobile accidents. But V2V technology could help avoid these and up to 81 percent of all traffic accidents, according to a study by the National Highway Traffic Safety Administration (PDF).

Using sensors already installed on the vehicles, the system gathers information about traffic and weather and transmits this information to other vehicles, so drivers have more time to react to road obstacles. The system can also activate a vehicle's accident avoidance technologies, such as electronic stability control. … Read more

On a cloudy San Francisco day, a Ford Explorer followed two Ford Fiestas. The lead Fiesta slammed on its brakes, and before the second Fiesta reacted, warning lights went off in the Explorer, alerting the driver to the situation ahead.

The Explorer's apparent precognition was born of technology, a combination of Wi-Fi and GPS. The lead Fiesta used this technology to tell the Explorer that its driver had slammed on the brakes. The Explorer received this information before the driver of the second Fiesta in the lineup could react, and dutifully used warning lights and sounds to tell its … Read more

Beginning in August, the Department of Transportation will be running clinics to test driver acceptance of new vehicle-to-vehicle (V2V) technologies. The first clinic will be held in Brooklyn, Mich.,  with 100 drivers and 24 cars.

The following five clinics will be held in Minneapolis, Orlando, Fla., Blacksburg, Va., Dallas, and San Francisco. The DOT chose areas with a variety of conditions, from dense urban traffic to rural roads.

The cars in the trial will be equipped with Dedicated Short Range Communications (DSRC) devices and GPS, with which they can communicate their status to the other cars in the trial. … Read more

This spring Ford will be testing a fleet of cars around the country that communicate with each other. At what Ford calls "major technology hubs," it will use the vehicles to demonstrate vehicle to vehicle (V2V) communication technology designed to prevent accidents.

The concept of V2V communication is not new. Prototypes have been shown by various companies, such as Motorola, in which cars send out signals based on certain incidents, such as a breakdown or sudden, hard braking.

Ford's technology uses Wi-Fi, on a special channel designated by the FCC, that communicates specific conditions to any other … Read more

GM's booth at the 2007 Geneva auto show features a particularly featureless slot car setup. The orange and white cars racing around the track show no marque or model distinction, instead designed to represent an "everycar," just as the featureless buildings around the track represent an "everycity." This display is not intended to demonstrate GM's lack of style, but rather its vehicle-to-vehicle (V2V) communication technology. As the cars race around the track, another car pulls out of a parking garage, causing an obstruction. Both approaching cars receive a warning through their V2V hardware, and … Read more
