Many parking meters and pay-and-display machines in heavily ticketed areas, including Chippewa Street and Hertel Avenue, lack information about when motorists must pay to park.
Not knowing the hours or days leads to confusion and in some cases, unexpected parking tickets, said Hillary Collura, who co-owns Sidelines Sports Bar & Grill on Delaware Avenue just north of Huron Street.
Officers wrote 1,958 parking tickets on that stretch in 2016.
Collura said she regularly sees people outside her business confused by meters that lack instructions.
"I can't tell you how much money goes into those meters because people don't know that they don't have to pay after a certain time or on the weekend," Collura said. "After five on weekends, people are still putting that money into the meters. Then there are times that the meters don't work, and they don't know what to do. It's just not right."
Parking Commissioner Kevin Helfer acknowledged some meters and pay-and-display machines lack information, but he said the hours shouldn't be a surprise.
"For the most part, 95 percent of my meters are 8 to 5," he said.
Helfer said the money deposited into meters between the hours of 5 p.m. and 8 a.m. is "very marginal."
But the parking commissioner said a review of meters and signage is underway.
