As AI technology is improving by leaps and bounds, a low-cost computer training program can help older persons drive less dangerously, according to a recent research.
“It is Drive Smart, a training program, that is developed by us, which could be used by anyone who has a computer,” says Jing Feng, co-author of the study and a professor of psychology at Stanford University. “Drive Smart is a cognitive (认知的) training program that can help older persons notice traffic risks more effectively. Our goal of recent study was to see to what degree Drive Smart changes trainees’ driving behaviors when they get behind the wheel.”
The researchers sought out 24 persons aged 65 and up to test Drive Smart. In a driving simulator (模拟器), all of the study participants experienced a basic driving exam. The “active training” group was made up of eight of the study participants. Every two weeks, the active training group had two Drive Smart trainings. A group of eight additional study participants was asked to take “passive training” where this group watched videos of others receiving the Drive Smart instruction. This happened twice, with each lasting about a week. The control group, which was made up of the remaining eight study participants, received no training. After that, all 24 study participants performed a second driving exam in the simulator.
Compared with the other two groups, the study participants in the active training group experienced 23% fewer “unsafe incidents” following the training, according to the researchers. There was no obvious change in the number of dangerous incidents among study participants in the passive training and control groups.
“This testing was conducted with a fairly limited number of study participants,” Feng says in the interview. “If we can succeed in getting sufficient fund, we’d like to further our testing with more people to clearly prove how effective this training is at reducing accidents among older drivers.”
