It had been a fairly smooth drive so far.
Junior civil engineering major Maria Martello glanced down at her lap as another text message flashed across her cell phone screen. At first, Martello was careful to keep one eye on the car in front of her as she typed out her response, but before she knew it her eyes had fixed themselves onto her keyboard for just a few seconds too long.
By the time she glanced back up, it was too late — the car ahead had stopped two seconds earlier and she did not brake in time.
Flustered, Martello tried to regain her composure and continue on with her drive as her phone buzzed once more. Still somewhat confident in her ability to multitask, Martello scrambled to type out another message only to look up and see she had missed seeing the brake lights ahead yet again.
And again. And again. And again.
“I’m sorry, I’m probably killing everyone!” a flustered Martello cried from her seat in front of the computer screen in the Maryland Day tent.
Martello was one of many students and other visitors who stopped by the “Reaction Time Delay from Texting While Driving” exhibit outside the engineering building on Saturday. Presented by the students of ENEE 133: Engineering in Medicine, the experiment simulated the experience of texting while driving as students recorded people’s reaction time to brake lights appearing in front of them.
“We’re really here to share knowledge and collect data on a current issue,” engineering professor Mel Gomez said. “We try to make it as close to the actual experience as possible.”
Here is how the experiment works: participants would sit in front of a model car with working brake lights on a small tripod, and every time the brake lights came on the participants had to press a handheld switch in their lap. At the same time, they would be texted questions, starting with easy “yes or no” questions and progressing to messages that required them to use an app on their phone.
Gomez said the average reaction time for most participants that day was five seconds — which at 65 mph, roughly equates to the distance between the engineering building and the “M” traffic circle. Some even had their eyes on their phone for 15 consecutive seconds.
And for Martello and many of the other visitors that day, it was a definite wake-up call.
“A lot of the time as students we feel like we’re invincible, like ‘Oh no, nothing will happen, it’s okay,’” she said, but added jokingly, “I’m sorry for killing everyone. … I’m a valid test subject because I text and drive a lot, but if it’s really this
dangerous, I might kill someone.”
