Brooklyn buses and routes have been named among the city and borough's worst by the New York Public Interest Research Group.

The group's Straphangers Campaign annually "awards" poor bus service with the "Pokey" for the slowest route and the "Schleppie" for the most unreliable.

The most unreliable bus route in Brooklyn is the B12, which the report found to "bunch" more often than others. Bunching occurs when two ore more buses arrive at the same stop at the same time, meaning they're not operating on schedule. More than 20 percent of buses on the B12 route were prone to bunching. The B63 route also won a Schleppie.

In Brooklyn, the Schleppie went to the B63, which was found to travel at an average speed of 4.7 mph. The citywide Pokie went to Manhattan's M42 bus, which the campaign says is slower than a running chicken.

The S48 was the fastest bus citywide, with an average speed of 7.3 mph.

"Improving bus service is the focus of the first major reform plan Transit President Andy Byford announced since starting the job this year," an MTA spokesperson said in a statement. "His comprehensive Bus Plan prioritizes completely redesigning the entire bus network in collaboration with NYCDOT and the NYPD."

The MTA says nearly 2 million people use its buses on an average weekday, contributing to an annual total of more than 600 million bus rides a year.
