Applied sciences can assist drivers keep the two-second rule to enhance highway security and site visitors circulation

The 2-second rule, taught in driver’s ed lessons throughout the nation, is a rule of thumb that helps drivers keep a secure distance from the automotive forward at any pace. Adhering to the two-second rule may be tough. A group of engineers led by Dan Work, affiliate professor of civil and environmental engineering, has developed an assistive expertise to assist drivers keep this steering to clean out site visitors jams and enhance security.

A preprint of the article, “CAN Coach: Vehicular Management by way of Human Cyber-Bodily Techniques,” was revealed by arXiv on April 8, and the paper was introduced on the ACM/IEEE Worldwide Convention on Cyber-Bodily Techniques throughout 2021 CPS-IOT Week Could 18–21. Researchers on the undertaking embody Matthew Good, a present graduate pupil, and Jonathan Sprinkle, PhD’03, one of many College of Engineering’s latest professors of pc science.

Work’s group launched a controller space community coach to automobiles—a system that provides real-time suggestions to drivers utilizing radar knowledge containing pace and place relative to the automotive forward. Their aim was to see if they may use sensors already accessible inside automobiles on the highway to efficiently assist drivers keep a secure distance—in essence to drive in a means no human can do alone, mentioned Work, who is also a 2021 Chancellor School Fellow.

The expertise was profitable. By evaluating six drivers with and with out the CAN coach, the engineers decided that drivers with the assistive expertise got here nearer to and maintained the two-second rule. Drivers utilizing the coach lowered the common time-gap error by 73 % and improved consistency, decreasing the usual deviation of the time-gap error by 53 %.

“This experiment offers us each indication that when drivers are given suggestions by the automotive, they’ll accomplish advanced driving duties,” Work mentioned. “We at the moment are exploring how coached human drivers could finally assist enhance site visitors circumstances total.” Work’s group intends to broaden the experiments to bigger cohorts of drivers and is trying into creating techniques that ship personalised suggestions that improves efficiency and minimizes intervention.
