In the future your car's brakes will know when to stop; the traffic lights will know when you're coming; and your cell phone will let just about everyone know how fast your car is moving.

Those views of the future were shared in Augusta this week as more than 100 users, suppliers and designers of transportation technologies assembled for the 10th annual meeting of the Intelligent Transportation Society of Georgia, held at the Augusta Marriott Hotel & Suites on 10th Street.

The meeting, which concluded Tuesday, was a forum for the major players in transportation technology to come together and share developing technologies for everything traffic related, said Marvin Woodward, president of ITS Georgia.

"It's just a chance for us to learn from one another," Mr. Woodward said.

Smart technology, including early collision-warning systems that automatically apply pressure to the brakes and weather alerts that appear in the car's windshield or dash, are under development by major car manufacturers and were highlighted during the meeting, Mr. Woodward said. He expects that drivers will begin to see some of the technology appear on showroom floors within the next five to 10 years, while others are already here.

"You're starting to see a little of that technology starting to occur," he said, citing the 2007 Lexus LS460, which can parallel park and back itself into spaces.

Bill Wells, the director of communication for ITS Georgia, said cars that "talk" to one another and to major transportation-management centers are on the horizon. He said the technology would curb congestion on highways by giving drivers early warning of accidents or other problems.

But not all of the technologies participants heard about were years away. Several changes are already used in Georgia, he said.

In Cobb County, traffic signals that detect the number of cars on the road and communicate with other signals in the area are being tested, he said. The signals would adapt to the traffic flow and use more green or red lights accordingly. Current signals use a computer to set a fixed time for green and red lights, depending on the time of day, with sensors that might be tripped by cars.

"This is even more adaptive than that system," Mr. Wells said.

Testing also is under way in Macon and Atlanta on a system that would provide real-time speed and travel times based on drivers' cell phone signals, Mr. Woodward said.

Developed by the Atlanta-based AirSage company, wireless signal extraction, or WiSE, technology, would take anonymous signals provided by phone companies and create a map for motorists. It would also allow transportation planners to get more current data on roads that are difficult to track or not as heavily traveled as major highways, he said.

"The same thing could occur here in Augusta," Mr. Woodward said. "We could provide a map with traffic information in almost real-time."
