Passage TwoQuestions 16 to 20 are based on the following passage.This is one of two schools in Richmond where the city has installed new enforcement cameras to catch speeders. Fitz Patrick has two children at the school. She is also a traffic safety advocate for the nonprofit Greater Richmond fit4KIDS, which is why she owns a radar gun(雷达测速器).Still, Fitz Patrick has mixed feelings about the speed cameras. She would rather see the whole street redesigned to discourage speeding and protect walkers and bicyclists. But she also knows that will not happen any time soon.The number of traffic deaths has risen sharply over the past decade, and safety advocates around the country are desperately searching for anything that will get drivers to slow down. But critics say speed cameras can be a financial burden on those who are least able to pay. Still, they have earned the support of important safety advocates, including onathan Adkins, the chief executive officer of the Governors Highway Safety Association.Police departments in many places have scaled down their traffic enforcement. Adkins says, and speeding and careless driving seem to be getting worse. He says automated cameras can help fill that blank. "The question is, how do we arrange them in a fair way with the public support?" Adkins said.No one likes getting a speeding ticket. But the objections to automated traffic enforcement go deeper than that. "It is doubtful that safety is the real goal," said Jay Beecher, with the National Motorists Association, a driver advocacy group."We need to make sure that our cities have all the tools that are effective to reduce traffic deaths," said Laura Friedman, a state lawmaker in California who sponsored the state law authorizing automated cameras. "We make sure it can't be a money grab, because the money can only be used for physical speed-lowering improvements on the same streets where you're using the cameras," she said. "So it's really about changing the culture and slowing traffic down."16.
