Like it or not, autonomous vehicles are on the way, and much is being done to study their integration into the world's transportation networks. As part of its own development of driver assistance systems, General Motors has begun to look driver behavior behind the wheels of self-driving vehicles; innovations like Cadillac semi-autonomous Super Cruise are designed to "ease the driver's workload" on the highway, but it will be good to know what drivers plan on doing to occupy their time.

The main finding so far is that "Staying aware [is] considered key to autonomous vehicle operation," which would seem to make the most basic kind of sense, but the additional assessment is that "driver attentiveness can be improved through advanced driver assistance and safety features." Basically, the more your car does for you, the more it will need to be able to do in order to ensure everyone's safety.

The driver aids that will be available on the 2013 Cadillac ATS this year and the 2014 XTS next year continue the march toward self-driving cars, which some predict might come as soon as this decade.

GM Studying Operator Behavior in Self-Driving Vehicles
Staying aware considered key to autonomous vehicle operation

DETROIT (2012-06-20) – How would driver behavior change in the self-driving vehicles that could be available by mid-decade?

General Motors and its research partners recently tried to find out by studying how non-driving activities influence driver behavior in self-steering, semi-autonomous vehicles. One key finding is that driver attentiveness can be improved through advanced driver assistance and safety features.

"Drivers are already engaging in risky behavior, and are likely to continue doing so given the prevalence of smartphones and other portable electronics, so why not make it safer for them and the people around them," said Dr. Eddy Llaneras, principal investigator at Virginia Tech Transportation Institute on the study. "Offering some form of vehicle automation with the proper safeguards might be better than what is happening on our roads today."

More than one in three drivers surveyed in the AAA Foundation's 2011 Traffic Safety Culture Index, admitted to texting or emailing while driving, despite the vast majority of those surveyed agreeing such behind-the-wheel activities are unacceptable.

The GM study examined the demands on the driver's visual attention in hands-on steering and automated steering, both with full-speed range adaptive cruise control engaged. The studies took place in a driving simulator at Indiana University-Purdue University in Indianapolis and with VTTI on a GM test track in Michigan.

When engaging in non-driving activities, drivers tend to split their visual attention between the roadway and secondary tasks by making relatively frequent, but brief off-road glances. The study showed that advanced driver monitoring and assistance features, such as Forward Collision Alert, increases drivers' focus on the road ahead by 126 percent when automated steering is in operation, which increases detection and response to roadway events.

"People have dreamed of having self-driving cars for decades, but having that capability will be a major adjustment for people when it is first introduced," said John Capp, GM director of Global Active Safety Electronics and Innovation. "This study is helping GM and its research partners determine the best methods for keeping drivers engaged."

The foundation for these future systems is the Driver Assist Package that will be available in November on the all-new 2013 Cadillac XTS and ATS sedans. The package includes features such as full-speed range adaptive cruise control and automatic emergency braking, which are designed to help prevent collisions caused by human error. The human factors research underway is helping GM and its suppliers identify what new technologies will be needed to ensure safe operation of future autonomous systems.

When asked, some study participants expressed strong interest in having a vehicle that could drive itself, particularly for long trips when lane centering and full-speed range adaptive cruise control could help lighten the driver's workload.

The Federal Highway Administration helped pay for the study but does not necessarily endorse all its findings.

GM, its partners and others are continuing to study the effectiveness of the driver monitoring systems, new ways drivers interact with their vehicles, and other active safety technologies that are key enablers for autonomous vehicles. These technologies are expected to ease drivers' workload when traffic and road conditions allow, but they are not intended for drivers to completely "tune out."

"At GM, we recognize that autonomous vehicles will require robust safeguards," Capp said. "By studying driver behavior in automated driving scenarios we are better able to identify the types of driver assistance and safety features that automated cars will need."

General Motors Co. (NYSE:GM, TSX: GMM) and its partners produce vehicles in 30 countries, and the company has leadership positions in the world's largest and fastest-growing automotive markets. GM's brands include Chevrolet and Cadillac, as well as Baojun, Buick, GMC, Holden, Isuzu, Jiefang, Opel, Vauxhall and Wuling.

      The best way to not have fun driving a car! You still have to pay attention, but you don't have to act. If you yanked out your E-reader, you'd be ticketed. Maybe someday. The line between telecommuting and actually commuting will get really blurry. Guess what? Your boss will get two extra hours out of you everyday! For the same pay! Yahoo!

      I would think that the more a car does, the less a driver will monitor it. It'll be a boon to those that would normally drink-and-drive, text-and-drive, etc...

      i honestly am waiting for autonomous cars; they will rid the roads of all the idiots who drive distracted and who hate to drive as well. i'll enjoy zipping around the old fashioned way, rowing my own cogs, and going as fast as i want because there will be little or no need to enforce speed limits.

        The Insurance companies are extremely interested in this feature. Google's autonomous vehicle engineers have told me that the insurance companies they have been working with are excited by the future of autonomous driving technology with respect to lowering their costs. Even the more skeptical insurance companies I've talked with said that they would change pemiums on autonomous vehicles until the actuary data comes in. If the vehicles are safer, they will lower they rates. If they are less safe they will raise them. European Insurance companies already give significant insurance breaks for Volvo's City Safety collision avoidance feature:

        I'll be straight ,as a car enthusiast I hate this tech. But, on your point I disagree. If the tech is good it will be proven to be safer and I bet you will find the opposite to be true. Just like some insurance companies won't insure certain sports cars now, insurance companies will refuse to insure drivers of cars without this system because they will be an increased liability.

      Lexus has a form of this already in the flagship LS. Its called the advanced pre-collision system. It has a steering wheel mounted camera that watches the driver and stereo-nightvision cameras with radar sensors built into the front end. You have to hold pressure on the wheel for it to stay engagd but it will actually torque the steering wheel to somewhat steer for you. Benz, BMW and infiniti are also close behind using the rear brakes to help pull the car back into the center of the lane and vibrations in the wheel. I dont think cadillac even offers active cruise at this point?

      I don't think it's real in the near future. This may be possible in few conditions like road surface, marking, traffic etc. This is far way from reality in some states or countries. It needs to be equaled to one level and moved all together forward. 8-10 years for it to happen. It's my opinion.

      It's interesting that scientists tell us we are intelligent beings capable of learning and adapting,but when it comes to driving it's like they're saying:"It's impossible!!!No matter how smart one person is,it CANNOT drive.We weren't made to drive.If God did create us,he didn't want us to drive".Unfortunately,this appears to be the automotive future.

      If it's autonomous, why should I pay any freakin' attention at all?

        In fact, I believe autonomous tech ought to make drinking and driving legal.

      Just one more thing to make American drivers even more vapid than they already are.

      Not like anyone will read this or pay attention to it, but my few cents are as follows: 1. Why get a license? Seriously, people who have no interest in driving should not. This autonomous driving crap is for people who just want to pay money to have their car drive them to the destination with out having to pay attention to the road and just arrive . GET OFF THE ROAD. YOU DONT DESERVE TO DRIVE. GET ON A TRAIN OR CALL A CAB. 2.Automakers are developing this in conjunction with the potential to market it as the next big automotive advancement. Next thing we know, the grey haired (over paid bags of crap that are elected with a popular vote via money that know no limit to a greased palm ) congressional people are like, ya, lets do this if we can create jobs(votes) and put this technology on the road to create a safer road going experience (votes) .. blah blah blah 3. Who is at fault for an accident involving an autonomous car in the event of a malfunction? Enjoy the litigation everyone. Trust a black box? Trust a lawyer for a corporation or an insurance company? I dont think so. The roads are not for cars to be driven by computers and I dont give a crap about anyone who says it is the wave of the future, I will gladly run one off the road and see how it reacts.
