如果快速执行摄像机促使驾驶员放慢脚步,那么有多少人会反对他们?事实证明,很多。他们正在使公路施工事故的挑战和安全性的挑战变得复杂,因为在此类摄像机上的禁令不排除道路工作区。由于大多数州尚未部署这样的系统或通过使用其使用的法律,反摄像机情绪可能是一个重大障碍。

根据州长公路安全协会的说法,伊利诺伊州首先允许Speed-Radar执法,限制了使用摄像机在建筑区和收费公路中违反违规行为的使用机票。2010年,研究表明,工作区摄像机将汽车和卡车速度降低了3至8 mph,减少了超速车辆的百分比并减少了致命的撞车事故。其他州遵循伊利诺伊州的领导。该州的快速执行摄像机“做得很好。他们正在发送正确的信息。”伊利诺伊州相关总承包商执行董事比尔·弗雷(Bill Frey)说。“公众没有意识到这是为了他们的安全。我们不是要得到他们。”

根据该网站上发布的数据,在过去的15年中,工作区风险管理计划的结合有助于将美国的工作区交通事故数量减少到2014年的669人,从2000年的1,026人减少到669人。workzonesafety.org。这些方法包括计划,标牌,交通管制,速度限制执法和驾驶员教育。

在这些年中,研究填补了有关危险来源的统计图。最近对明尼苏达州驾驶员的研究表明,年轻和年龄较大的驾驶员往往比中年驾驶者加​​快速度。新利18备用其他研究表明,重型卡车涉及所有工作区死亡的三分之一。上个月,在内布拉斯加州列克星敦附近的80号州际公路上发生的五人车祸中,有6人死亡,当时一名分心的卡车司机将一辆小型货车往后一辆小型货车,当地报纸描述为“正面”跨界建筑区。据称,该驾驶员被指控犯有许多违规行为,进入了一个9英里长的工作区,该区域的速度限制从75英里 /小时降至65英里 /小时。

在14个州被禁止

Automated highway radar-camera systems would seem to be a logical step. But 14 states have banned them, although some of those states make exceptions for work zones and schools.

倡导驾驶员及其权利的协会对相机有不好的话要说。他们声称这些摄像机最终是政府币牛,产生虚假的读数,容易出错,剥夺驾驶员的基本权利,实际上可以使高速公路和道路更加危险。马里兰州驾驶员联盟的评估是,安全福利是混合的,引用英国的研究表明,该联盟声称“速度摄像机并没有降低高速公路工作区的事故率”。新利18备用联盟在其网站上索赔一般而言,雷达相机系统丰富了提供设备的供应商和承新利18备用包商。

司机团体说,更好的策略是雇用更多的州警察观看工作区。然而,在工作区域中的巡逻车可能受到建筑的性质的限制,仅坐在某些地方,并且可能没有驾驶员的空间。

Whether the cameras help is not a purely academic question for the driving public. Roughly 85% of the victims of work-zone accidents are drivers and passengers.

的7个州允许radar-camera系统s in work zones—Colorado, Illinois, Louisiana, Maryland, Oregon, Tennessee and Washington—not all have put cameras to use. Fines differ, too. Washington state collects $137 for a first violation. In Illinois, an initial violation will earn a $375 penalty, according to presentations by state officials.

在宾夕法尼亚州,两名州参议员提出了一项为期五年的试点计划。其中一位戴维·G·阿格尔(David G. Argall)(R)在一封电子邮件声明中说,几名高速公路建筑工人及其家人要求在工作区中寻求更强大的安全激励措施。

Simply increasing work-zone length or lowering speed limits won’t do the job, says James Baron, a spokesman for the American Traffic Safety Services Association, a Fredericksburg, Va.-based association of road-safety-related manufacturers and service providers. Because work zones come in so many different types and move with the work progress, stretching out the zone and further lowering speed limits isn’t a good idea, he says.

人性也带来障碍。联邦高速公路管理局的工作区管理计划经理Jawad Paracha解释说,驾驶员倾向于忽略迹象和警告,并以他们感到自在的驾驶速度进行速度。

A better approach would be to install intelligent systems that connect to message boards and change as sensors feed in new data about weather, time of day, traffic conditions and new surroundings, Baron says.

Research Backs Camera Use

马里兰州的SafeZones倡议是最具争议的摄像机速度执法计划之一,2009年在头六周发行了近8,800张门票。

In a document on the Maryland State Highway Administration’s website, the department claims that SafeZones cut by 80% the number of cars exceeding the speed limit by 12 mph in work zones. It also states that, of almost 1 million citations issued by SafeZones cameras, only two tickets were refunded because they were issued in error.

State officials claim the cameras have a 95% rate of capturing legible photos of speeder license plates, but that wasn’t always the case. A state audit in 2012 found that SafeZones cameras failed to capture clear enough photos of speeders’ license plates, so only 44% of cars caught speeding by the cameras received tickets. The office estimated that the lost revenue from those uncalibrated cameras was at least $850,000.

该州的原始提案要求安装摄像头和收取罚款所需的摄像机,这些摄像头可以在95%的时间内捕获车牌的清晰照片。该数字减少到90%,而纽约州则认为合同安装摄像头并收取罚款。

2月,州参议员建议废除使用相机的权利。现在,该计划的命运仍然不确定。

在大多数情况下,研究支持在工作区中使用相机。2010年的一项俄勒冈州的一新利18备用项研究发现,照片雷达执法“对减少建筑工作区的超速车辆数量有重大影响,”导致速度平均降低了23.7%。拆除相机后,驾驶员恢复了通常的速度,标牌和工人的存在“对超速行动没有明显的影响。”

Similar studies in North Carolina and Arizona found decreases in crashes and average speed from both mobile-camera enforcement and fixed-camera enforcement. The 2009 Arizona study showed that crashes during non-peak traffic periods decreased by 44% to 54% and average speed decreased by 9 mph.

Using a driving simulator and eye-tracking glasses, a 2016 experiment in Minnesota examined whether “Your Speed Is”-type signs—often used in tandem with cameras—distracted drivers. The experiment found that the speed display signage was not a significant distraction.

尽管进行了支持,但在速度相机方面,州议员可能会谨慎行事。

When Indiana considered a camera speed-enforcement bill last year, opponents worried whether the absence of real-time police review of the camera footage would violate due process and whether camera vendors would receive income per ticket issued. One thing seems certain: Radar speed- enforcement systems will need champions who can make the case that work-zone cameras aren’t a new kind of speed trap but are a vital protection to drivers themselves.
