More state transportation agencies are using aerial drones, and overall commercial use of the devices is expected to continue to climb, though not as dramatically as predicted in 2017, recent reports say.
Results of an American Association of State Highway and Transportation Officials study, released on March 27, show that 20 state departments of transportation have made use of unmanned aerial systems (UAS), as drones are more formally known. AASHTO said another 15 DOTs are studying how they might employ the aerial technology.
Those figures are up from the numbers state DOTs reported to AASHTO in 2016. That earlier survey showed that 17 agencies had studied or used drones and another 16 were either examining them, helping to develop drone policies or supporting research on the technology.
今年的AASHTO无人机报告基于44个州的回答，他说，将无人机合并到工作中的所有20个机构都使用它们拍摄公路建设项目的照片和视频。18luck官网
Fourteen of the 20 say they use them for surveying, 12 for public education and outreach and 10 to inspect bridges.
In addition, eight DOTs use UASs for emergency response, six to inspect pavement, five to conduct scientific research, two to control and monitor traffic and one to inspect high-mast light poles.
此外，有27个国家表示，他们正在增加全职员工来运行和维护其无人机舰队。
雇用UASS的20个州机构是阿拉斯加，亚利桑那州，科罗拉多州，特拉华州，佐治亚州，爱荷华州，缅因州，密西西比州，蒙大拿州，内布拉斯加州，内布拉斯加州，内华达州，新泽西州，新泽西州，北卡罗来纳州，俄亥俄州，俄克拉荷马州，俄克拉荷马州，俄克拉荷马州，俄勒冈州，俄勒冈州，俄勒冈州，宾夕法尼亚州，宾夕法尼亚州，田纳西州，田纳西州，犹他州，犹他州，犹他州和西弗吉尼亚州。
无人机研究阶段的15个国家点是阿拉巴马州，康涅狄格州，爱达荷州新利luck，伊利诺伊州，印第安纳州，堪萨斯州，肯塔基州，肯塔基州，路易斯安那州，马萨诸塞州，密歇根州，密歇根州，明尼苏达州，新罕布什尔州，新罕布什尔州，南卡罗来纳州，德克萨斯州，德克萨斯州和弗吉尼亚州
Bud Wright, AASHTO executive director, said in a statement, “Drones are being used to significantly cut the time it takes to gather data, which is leading to major time and cost savings.”
The Federal Aviation Administration’s latest annual aerospace forecast, released on March 15, says that the number of non-hobbyist drones—which for the most part have commercial applications—is expected to rise to at least 451,800 in 2022, a 184% increase from 2018. By comparison, in 2017, a FAA “base” forecast showed 422,000 non-hobby drones in 2021, an increase of 291% over five years.
FAA的新“高”预测设想了五年内717,895个商业UASS。去年对五年级的高度预测是160万的看涨。
