Some Bay Ridge parents say they're worried about their children's safety due to the amount of speeding cars outside their school.

They say drivers zoom past P.S. 30 on Fourth Avenue during rush hour.

According to a recent study by the transit group Transportation Alternatives, 92 percent of drivers exceed the speed limit there. The group says drivers outside P.S. 30 were the worst offenders of the six schools monitored nationwide. No. 2 on the list are speeders outside P.S. 97 in Gravesend.

The speeding study is aimed at pushing the state Senate to expand its speed camera program from 50 to 140 school zones. Parents say they think the cameras would deter speeding in those areas.

Speeding is down by nearly two-thirds and pedestrian crash injuries decreased by 23 percent in places where speed cameras have been installed, according to the city Department of Transportation.
