It wasn’t just random residents ignoring the safety of the neighborhood. Popke captured a local police officer and a public transportation bus ignoring the sign as well. He uploaded an edited clip of his hour and a half of recording to Facebook and YouTube.
Officials quickly took notice.
"If you document something and show people the breadth of the problem, they will take action," Popke said.
Two days after his video was posted, the city removed trees that were obscuring the stop sign, and moved the signs to more visible positions, adding “stop sign ahead” signs to warn drivers.
A Jersey City police officer was stationed at the intersection on Monday, handing out tickets.
