"There's a lot of jaywalking going on, and a lot of people speeding through here," he said. "It's a combination of people not watching where they're going and people speeding through here."

Day, who represents a district that encompasses part of the bar area, said the idea has been considered but would be "extremely difficult" because a detour would route traffic through neighborhoods.

"I don't think that's the best answer, but I don't think it has been taken off the table completely," he said.

Melissa Lam, who was a student at the university before she became manager at Plato's Diner, said the road has become so dangerous that she no longer rides her bicycle to work. She said the various stakeholders, including students and residents, need to work together.

"I think we look too much at this issue of whose fault it is instead of looking at a solution," Lam said.

After Pacanins' death, officials from College Park, the university, police and SHA created a public relations campaign called "Walk Smart College Park!"

Loh said he's visited U.S. 1 late on weekend nights to see dangerous pedestrian and driver behavior for himself. He's seen students near a bar on one side of the street spot friends across the street and dart across, even though they are far away from a crosswalk.

"There are literally scores of young people crossing in the middle of the street after midnight. It's not just one or two," Loh said.

Loh said students also need to take responsibility for their actions, and the university has reached out to fraternities and sororities to spread the word. But, he said, that's not enough.

"When you have hundreds of people crossing at any given time because there are thousands in these bars, just pleading with them is not sufficient. Just issuing tickets isn't going to do it," he said.

During the spring semester, Loh said, campus police ramped up their efforts. On weekends, they parked cruisers in intersections, conducted foot patrols and set up temporary barriers with police tape along the sidewalks — all in hopes of funneling pedestrians toward crosswalks and out of the road, Loh said. None of those practices were in place this past weekend when Oni was killed because of the smaller summertime crowds.

"It breaks my heart she just graduated from college. … She did not deserve to come here and be killed," Loh said.

Kayleigh Poulsen, a May graduate and server at Cornerstone, said she knew Hubbard, who was killed in January. Something more needs to be done, she said.

"It's terrifying," Poulsen said. "You want to feel safe walking around. You want to feel like people are being smart, especially when they leave our businesses. … At the end of the day, it's a lot of people; it's the busiest road in College Park. It's scary."
