3号地区是英格兰高速公路的第二大网络,载有该国整体交通流量的10%。它包括M27,M3,M4,A3,A303和Hindhead隧道,并在南部的几个主要城镇和城市之间提供了几个主要城镇和城市之间的主要链接路线,以及南部的伯恩茅斯,南安普敦和南部的伯恩茅斯。

大型区域最近进行了升级,以设计,更换和安装道路标牌,以使道路上的渐变更清晰可见。需要进行地形调查以捕获设计的功能。大规模项目需要对车道和边缘进行详细的地形调查,每个调查测量长600米capturing:

  • Carriageway extents
  • Road markings
  • Crash barriers
  • 频道
  • 路缘和遏制堰
  • 沟渠
  • 边缘水平
  • 铁工程框架
  • 标志位置
  • 交通循环
  • 高架电缆
  • Electrical boxes
  • Railings
  • Fences
  • Steps
  • Bridge soffit levels
  • Pier positions

Sun Hill Surveying and Engineering Ltd., a specialist land surveying and engineering firm, was commissioned by Kier to survey 119 sites on behalf of Highways England Area 3.


From months to day

With more than 30 years’ experience focusing on the civil engineering sector throughout the United Kingdom, Sun Hill brought a modern approach to surveying the large project with itsLeica Pegasus:两个移动映射平台。

传统上,使用激光扫描仪,总站和GPS进行调查,是每天收集数千个数据点的漫长而长期的操作。亚博5分钟快三通常,这将使测量师大约每个站点大约在现场完成。此外,要调查这许多站点,将需要119个单独的交通管理装置。
有了这样的项目,与所有相关人员相关的健康和安全风险都有很大的健康和安全风险,在白天和黑夜的所有时间内都在车道和边缘。在Pegasus中发现了一种更安全,更具成本效益的方法:两个可以按时和预算运送该项目。

With mobile mapping, access to all sites was left clear with no road closures as the Pegasus:Two acts in the same way as any other public vehicle when collecting the 3D geospatial data. In total, the surveyors travelledmore than 6,000 kmusing the mobile mapping platform to collect millions of points per second. There wasno disruption to the network由于不需要流量管理,因此流量流量正常继续。

通过移动映射,调查人员的安全性也大大提高了,因为在道路上不需要测量人员或交通管理人员,因为所有数据都是从车辆的安全性中捕获的。测量师能够从点云创建传统的地形调查。

“Mobile mapping provided a rapid data capture solution for us,"Sun Hill移动映射专家Peter Bouchard说。With the Pegasus:Two, we saved time, reduced safety risk and maximised value by reducing a six-plus-month project to 12 days."


移动映射投资回报

由于使用Pegasus:两个,所有119个地点均已在only 12 days,没有交通管理,可以从办公室环境的安全中进行处理和提取。此外,对所有119个地点进行了调查并将其交付给Kiera week before the final deadline

Sun Hill was able to deliver this project绝对精度少于20毫米。然后,调查在交错的计划中进行,使站点可以优先考虑,并使某些站点能够比其他站点更早地进行。

“At Kier we aim to be at the forefront of technology,"said Chris Fuller, Kier Roads Value Stream manager.The Pegasus:Two is one of the most accurate mobile mapping units on the market. It has helped deliver significant cost savings as well as meaning we could eliminate traffic management completely from the project and all 119 surveys were delivered before the final deadline."
