What technology makes self-driving cars possible? Connectivity means cars have access to the latest traffic, weather, surface conditions, construction, maps, adjacent cars, and road infrastructure, he says.
Two of the most talked about self-driving advancements come from Google and Tesla. They take different approaches: Google is using lidar a radar-like technology that uses light instead of radio waves sensor technology and going straight to cars without steering wheels or foot pedals.
While technologies and capabilities continue to evolve toward making autonomous vehicles a reality, there are some hurdles. Right now, autonomous cars are legal only in a few U. Finding the gas leak may take considerable time, while It is close to many establishments and alleviates the problem of wading through endless traffic to catch flights. But it does come at a cost Alternative energy automobiles are on the rise contributing to the global effort to reduce carbon Thursday, November 4, Load more stories.

Nonetheless, 30 years later rear-end collisions caused by driver inattention remain a severe national problem, exacerbated by the proliferation of in-car distractions from cell phones, dashboard display screens, on-board navigation systems, email and social media connections, and more. Texting makes an accident 6. Technologies have arisen to mitigate these risks, but human factors research has highlighted shortcomings. As early as , behavioral engineer John D. Lee, now at the University of Wisconsin, and colleagues found that the use of speech-based email systems increased driver reaction time by about 30 percent.
Strayer, a professor of psychology at the University of Utah who studies the mental effort expended by drivers in various situations. In the face of chronic operator inattention, researchers have developed sensor-activated automated systems, such as automatic emergency braking AEB , front-facing radar, blind-spot monitors, and lane-departure warning systems, to compensate for driver distraction.
Human factors research has played a major role in the design of these systems. Repeated studies indicate that average driver response time often defined as the period between perceiving a danger and applying the brakes ranges from less than 0.
AEB systems, rapidly becoming standard equipment on many vehicles, have to be deployed within those constraints. But once a threat is detected by sensors, how soon should warnings be delivered? Human factors science also examined a related question: By what means should the driver be warned? Researchers compared the performance of visual, auditory, and tactile warnings when the driver was talking on a cell phone.
Today, driver inattention—and ways to reduce it or compensate for it— have become one of the most studied topics in human factors, and behavioral science is producing a prodigious volume of data on driver reaction to AEB and other features.
During those 3 years, according to IIHS estimates, the commitment will prevent 28, crashes and 12, injuries. The long-term success of AEB and other coming innovations will depend critically on how drivers react to them.
Indeed, human factors science will soon be facing one of the most daunting challenges in its history with the fast-approaching advent of self-driving cars, or autonomous vehicles AVs. In September , the U.
