The PPA reported that no-stopping violations in bus lanes dropped 51% since the program began.

Some of the city's most problematic locations saw even larger decreases, with violations falling by as much as 96%.
Among the locations highlighted by the agencies, violations at 13th and Market streets fell from 515 to 22 over the past year.
At 16th and Chestnut streets, violations dropped from 545 to 56, a 90% reduction.
Illegal parking in bus stops also declined.
According to the data, violations at bus stops fell 27% overall from June 2025 to June 2026.
SEPTA and the PPA introduced the AI technology last year to help keep buses moving through some of the city's most congested areas.
Officials say the program is changing driver behavior by increasing enforcement coverage beyond what is possible through traditional enforcement methods.

"A parking enforcement officer can only be on one corner for such an amount of time," said Corrine O'Connor, executive director of the PPA. "But now that you have cameras on the buses, then it's gonna seem to capture more vehicles that are doing that infraction. And once people realize that, that they're not really taking that chance anymore, then that's where you see that change in behavior."
Officials say the results have translated into fewer delays and faster bus service.
SEPTA said the effort helped reduce travel times by 3% to 6% on routes equipped with the camera technology.
The improvement comes as transit riders continue to experience bus speeds that remain below the national average.
The program has also expanded beyond buses.
In March, SEPTA and the PPA extended the enforcement technology to trolleys, becoming the first city in the country to use trolley-mounted cameras to enforce parking violations along trolley routes.
