Cars were moving at up to 55 miles per hour in both directions, and subjects had 30 seconds to "cross the street" on a treadmill synced to the virtual reality environment.
More Careless, or More Careful?
"It could be that they are missing safe crossing opportunities that they may have recognized if they weren't talking on their cell phones," says the study's lead author Mark Neider, a post-doctoral associate. "If you want a more positive argument, it could mean they are being more conservative or are trying to be more careful" because they are talking on the phone.
That may not be a big deal in a simulated study for which 36 students were paid $8 per hour. But in real life, if you're late for work or to pick up your kid at day care, the cell phone could become a real hazard. "In these cases, any impairment in the ability of that pedestrian to recognize and act on safe crossing opportunities is likely to increase the chance of an unfavorable crossing outcome, including pedestrian-vehicle collisions," the study says.
