A recent letter sent to ENR took issue with my story about a work site safety survey and how speed cameras are used.
“工作区中的速度相机是收入。如果没有，那么为什么我们不做像采用拉链合并的东西，并且第85次百分位数的速度限制？低速限制导致车辆之间的体面变化，促进尾随，恒定通过，迅速接近车辆，“宾夕法尼亚州普斯尼亚·斯科斯基·斯科斯·詹姆斯·斯科斯基倡导全国驾驶者协会，在阅读故事之后AGC对工作区崩溃的调查。
美国的相关总承包商，正如您所想象的，根据其调查，据说，68％的受访者在2019年工作现场至少有一个移动的车辆事故。
“我们确实有一个人在我们的工作区内加速和危险的问题，”宾夕法尼亚州AGC章为匹兹堡地区企业AGC章节的工业关系总监Jason Koss说。“驾驶和分心的驾驶确实发生了。“
AGC的数据来自200名成员承包商，该承包商进行道路和公路工作，只是该数据/
But as a reporter who's been around the block a few times, I did sympathize with Mr. Sikorski's complaint. He further elaboratesd in his letter that the state of Michigan's strategy is to put most freeway work zones behind concrete barriers, limiting crash risk from passing cars and allowing drivers to see that workers are safe.
Freeway limits are usually 70 mph in Michigan, but are sometimes reduced to 60 mph if warranted. If work areas are close to the travel lanes or there are some minor lane shifts, the basic limit drops by 10 mph. Signs tell motorists “45 Where Workers Present,” which forces drivers to look for workers who might be at risk, and slow down near them. The strategy seems to work for Michigan.
投诉速度相机的收入也非常生根。作为伊利诺伊州的居民，我知道这一切基于我完成的报告involving kickbacks to politicians to place both speed and red light cameras on roads, and how companies such as red light camera provider SafeSpeed LLC involved themselves in corrupt municipal politics.
But painting every speed camera operator as corrupt as SafeSpeed was is as wrong as saying a one-size-fits-all approach to work zone safety is effective in every state or for every department of transportation.
承包商需要与DOTS和市政当局沟通有关以保障人员安全的技术工作，并且DOTS和市政当局需要根据AGC和驾驶者群体等行业集团（如NMA）的承包商反馈和实际数据做出关于工作现场技术的决定。而不是基于政治家回扣和来自高位的命令。
There is certainly a role for technology, including speed cameras, to play in work site safety. But that role should not become a tool to take advantage of motorists. The needs of both drivers and workers can be accomplished with proper controls and transparent processes from DOTs, municipalities and, yes, local politicians.
但一个结果，驾驶者和承包商都不想要的是一个新利18备用本周介绍了涉及卡车司机，由他的手机分散注意力，他在明尼苏达州工作现场造成致命崩溃。司机于7月14日收到了三年监禁。
两组可以帮助避免这种情况type of accident if they leave the politics out and work together on solutions.
