The escalator has been a staple of American culture since it was first introduced in 1901, and it has become the most common way to travel through American cities.

But a new study suggests that, in the United States, it’s a poor choice, even for people who have trouble getting around in public.

The study by researchers at the University of Michigan and the University at Buffalo found that Americans who don’t use escalators are more likely to get stuck in traffic jams.

The researchers also found that people who don’ t have the mobility to get around the city using a car, bike or bus are at a greater risk of getting stuck in the city.

“If you don’t have the ability to drive yourself, or to walk or ride a bike, then the chances of getting into an accident are higher,” said Jennifer Smith, a researcher at the Michigan Transportation Research Institute (MTRI).

“If we have a lot of people who can’t get around and they don’t get on a vehicle, the odds are they’re going to get into an incident.

So it seems like a good idea to put them in the car, and if you’re driving, that will keep them out of an accident.”

The researchers analysed data from a nationwide study of traffic accidents in the U.S. from 2004 to 2014.

They found that nearly a third of all car-related traffic accidents were related to escalator accidents, and that more than two-thirds of the accidents involved pedestrians or cyclists.

The data showed that when people didn’t have access to public transportation, they were less likely to be involved in traffic accidents, the researchers found.

The number of escalator crashes increased by more than 1,000 percent in urban areas.

The most common reason for getting into accidents was a driver who didn’t want to pay a fare or didn’t know where the escalator was located, the study found.

More than 80 percent of escalators were located in inner cities, and the majority of escalaters were in high-density urban areas, where the average person had to get to work by foot.

People in those areas were more likely than those in other parts of the country to get involved in escalator incidents.

Smith and her colleagues compared the data from 2004-2014 to the data on escalator injuries from the National Center for Injury Prevention and Control, a nonprofit health research organization.

They compared the two datasets to see how many escalator fatalities occurred in each year.

“People were more at risk of accidents than people in other areas of the United Kingdom and Australia,” Smith said.

“But they were much less likely than people elsewhere.”

The study also looked at the impact of public transportation on escalators and found that it had little effect on accidents.

There were only 1,721 escalator-related fatalities in the study, but there were only 546 escalator collisions in the year before the study began.

The increase in escalators in the urban areas that were most likely to have escalator problems was the result of people using public transportation instead of driving or walking, Smith said, adding that the study also found no relationship between escalator safety and the number of public transit riders in a city.

The researchers suggest that people don’t need to get up early to get the most out of the escalators.

“They can use the escalates and get up as early as they want, and they can get to their destination,” Smith told the AP.

“So it doesn’t really matter if people have to climb up a ladder or if they have to walk across a street or whatever.”
