Google has been testing driverless cars on open roads

Internet search giant Google has revealed that, in an effort to help prevent traffic accidents, free up people’s time and reduce carbon emissions by fundamentally changing car use, it has developed technology for cars that can drive themselves.

Internet search giant 1691 Google has revealed that, in an effort to help prevent traffic accidents, free up people’s time and reduce carbon emissions by fundamentally changing car use, it has developed technology for cars that can drive themselves. Not only that, the company has clocked up 225,000km in testing.

According to Sebastian Thrun, software engineer behind the project and who was also behind Google’s Street View mapping system in which users can virtually travel down streets, “Our automated cars, manned by trained operators, just drove from our Mountain View campus to our 622 Santa Monica office and on to Hollywood Boulevard. They’ve driven down Lombard Street, crossed the Golden Gate bridge, navigated the Pacific Coast Highway, and even made it all the way around Lake Tahoe. All in all, our self-driving cars have logged over 225,000km. We think this is a first in robotics research.”

Google’s test cars are six 1686 Toyota Priuses and an 2125 Audi TT which use video cameras, radar sensors and a laser range finder to ‘see’ other traffic, as well as detailed maps to navigate the road ahead. Safety has been the company’s first priority in the project. The cars always have a trained safety driver behind the wheel who can take over as easily as one disengages cruise control. A trained software operator rides in the passenger seat to monitor the software. Any test begins by sending out a driver in a conventionally driven car to map the route and road conditions.

Thrun points to 1819 World Health Organisation figures that more than 1.2 million lives are lost every year in road traffic accidents. “We believe our technology has the potential to cut that number, perhaps by as much as half. We’re also confident that self-driving cars will transform car sharing, significantly reducing car usage, as well as help create the new ‘highway trains of tomorrow’. These highway trains should cut energy consumption while also increasing the number of people that can be transported on our major roads. In terms of time efficiency, the 324 US Department of Transportation estimates that people spend on average 52 minutes each working day commuting. Imagine being able to spend that time more productively?” Thrun asks.

”We’ve always been optimistic about technology’s ability to advance society, which is why we have pushed so hard to improve the capabilities of self-driving cars beyond where they are today. While this project is very much in the experimental stage, it provides a glimpse of what transportation might look like in the future thanks to advanced computer science. And that future is very exciting,” says Thrun.

    Update on autonomous cars: mastering city street driving
    In a recent blog post, Google’s director of their self-driving car project, Chris Urmson has given an update on the technology that he says is better than the human eye. Google’s autonomous vehicles have logged nearly 700,000 miles on the streets of the company’s hometown, Mountain View, California. Urmson says a mile of city driving is much more complex than a mile of freeway driving, with hundreds of different objects moving according to different rules of the road in a small area. He claims that

    California’s Autonomous Vehicle Testing Regulations require every manufacturer authorised to test autonomous vehicles (AV) on public roads to submit an annual report summarising the disengagements, or deactivation of the autonomous mode, of the technology during testing. Eleven manufacturers are currently testing autonomous vehicles on the state’s roads, seven of which (VW/Audi, Mercedes Benz, Google, Delphi Automotive, Tesla Motors, Bosch, and Nissan) were required to submit their first disengagement re

Huw Williams investigates Google’s strategy and David Crawford discovers what two principal rivals are doing to keep pace. In the first weeks of 2012 one company staked two divergent claims on the future of transport. One is the science fiction of only a decade ago, turned into reality: the driverless car. The other seems more prosaic, yet in its own way is just as significant a marker of the futur

    Driverless vehicles just around the corner?
    umors that self-driving taxis are about to hit the streets of Las Vegas have turned out to be untrue… but the age of the driverless vehicle is only just around the corner, as Pete Goldin finds out. From Herbie the Love Bug to Knight Rider to the cast of the Pixar film Cars, the autono­mous auto has long been a beloved icon in the entertainment industry. But how close is the fiction to fact? The general public might be surprised to find out just how soon autonomous vehicles could be driving on our roadways.
