Audis will count down time until light turns green
San Francisco — You’re stuck at a red light. It’s taking forever.
How much time until the light turns green? Ten seconds? Twenty seconds? A minute and a half?
Would you be more patient if you knew exactly how long it will take?
Audi is betting yes. The German luxury carmaker says several cars in its 2017 lineup will be available with a cloud-computer-connected countdown timer for red lights, displayed on the instrument panel and heads-up display.
The service is scheduled to roll out city by city, starting this year in Las Vegas; Washington, D.C.; Seattle; Portland, Ore.; and possibly others.
Government agencies already collect information from traffic signals and road sensors to help manage traffic flow. Now, participating agencies will contract with companies to sift that software and predict when lights will change from red to green.
Audi will pass along that information to drivers who subscribe to its broadband data plans.
How do drivers benefit? Audi believes they will feel less stressed in heavy traffic if they know how long they’ll have to wait for a green light.
“If you’ve got 45 seconds, you can take care of the kid in the back seat,” said Anuparm Malhotra, general manager of connectivity for Audi. “It’s a more relaxed form of driving.”
City air, theoretically, could benefit, too. Vehicles equipped with start-stop engines, like hybrids, could be programmed to shut down at a red light, saving fuel and wear and tear. That won’t be immediately available on the Audis, but it could be in the future.
Such systems might also be used to time a string of green lights and recommend a speed to help the driver make them all, or integrate with mapping systems to give advance warning of traffic tie-ups and suggest alternative routes.
The countdown clock is more than a gimmick. It’s an early indicator of dramatic changes in automobile transport as more connected cars hit the road.
“Traffic engineers will do their jobs better. Vehicles and drivers will make better decisions,” said Kevin Balke, research engineer at the Texas A&M Transportation Institute.
With technology at the point where it’s cheap enough and pervasive enough for cars to begin communicating with each other and with traffic management systems, new applications are beginning to flood in, Balke said.
Audi said the feature is not a smartphone app; it is integrated into the automaker’s communication system.
